SAFETY WARNINGS The following symbol is used in this Manual whenever it is necessary to draw the operator s attention on a safety issue. Safety rules for users or operators of the equipment and for nearby workers. This section contains safety rules to be followed for installation room and ventilation opening. 2.1 Fuel The heater must be matched to a suitable burner, using the fuel chosen for the equipment. The burner shall use the type of fuel it is set for, which is specified on the equipment plate and in technical specifications in burner s Manual. If the burner is fuelled with gas, gas supply pressure shall not exceed the range specified in the accompanying Manual. Before starting the burner/heater, check that: Gas supply specifications match those written on the rating plate; The grid of combustion air intake system is free from debris, leaves, etc.; The gas seal of the feeding system has been tested and approved in compliance with the law. The heater's fuel is the one specified for the unit; The unit is correctly sized to match required flow rate and includes all safety and control devices required by the law; Gas pipes and air distribution ducts for ducted heaters have been properly cleaned; Fuel rate of flow matches heater's rated input; Gas feeding pressure matches values on rating plate. 2.2 Gas leaks If you smell gas: Do not operate electrical switches, the telephone or any other object or device that can cause sparks. Immediately open doors and windows to ventilate the room. Close gas valves. Call for qualified personnel. 7 code HG GB ed.c-1509 rev.05

8 2.3 Power Supply The heater shall be correctly wired to an efficient grounding system, complying with existing regulations (CEI 64-8). WARNING: Check the grounding system or have it checked by qualified personnel, if necessary. Make sure network wire gauge suits the unit rated input shown on rating plate and in this Manual. The heater can be plugged into mains using a plug-socket only if the latter prevents any mixing up of phase and neutral wires. The system wire gauge in general, and cable section in particular, must suit the unit rated input shown on equipment data plate and in this Manual. Do not pull electrical wires and keep them far from heat sources. NOTE. A multipole switch with fuses and contact opening greater than 3 mm should be installed before the supply cable. The switch must be in a visible and accessible position and within a 3-meter radius from the control board. Any operations involving electrical components shall be performed by specifically trained and certified personnel. 2.4 Use Children and inexperienced people shall not be allowed to use any electrical appliance. The following precautions shall be adopted: Do not touch the unit with wet or damp parts of the body and/or barefoot; Do not leave the unit exposed to adverse weather conditions (rain, sunshine, etc.) unless the unit has been expressly designed to; Do not use gas pipes to ground electrical devices; Do not wet the unit either with water or other liquids; Do not put any objects on the unit; Do not touch moving parts of the heater while it is working. Avoid contact with hot heater surfaces. Such surfaces, generally located near the flame, overheat during operation and remain hot for some time after the burner has stopped. When use of the unit is to be discontinued, open the electric switch and close the manual valve on burner fuel piping. When the unit is to be finally decommissioned, ask professionally qualified personnel to do the following: disconnect supply cable from mains; shut manual valve on burner fuel supply and lock or remove its control hand wheel. 2.5 Venting Openings The room where a gas fuelled heater is installed must comply with relevant regulations as to the number and dimensions of venting openings, in order to guarantee optimum combustion and safety. Number, dimensions, and position of these openings vary according to national regulations. Please check with your installer. The heater, if not built for outdoor installation, shall be sheltered from rain, snow, and frost. If air is pulled from outdoor, the inlet must be protected by a rain deflector or similar device that prevents water from spilling into the heater. The room where the heater-burner group is installed must be clean and deprived of volatile substances that can be drawn by the fan and obstruct burner inner hoses or combustion head. Dust itself can be a problem if it is left depositing on fan blades, thus reducing fan flow rate and making combustion polluting. Moreover dust can deposit on the back of flame stability disk in combustion head, degrading air-fuel mixing ratio. 2.6 Maintenance Before running any servicing or cleaning, disconnect power and gas supply by means of main ON/OFF switch and/or appropriate detection devices. In case of failure and/or insufficient running standards, switch off the heater and do not attempt to repair it directly. Contact the authorized Service Centre. Use only original spare parts for repairs. Failure to follow above instructions could compromise the unit safety and shall void the warranty. 2.7 Transport and Handling The heater includes supports and lifting rings. Unload the heater from truck and move it to the installation place using a convenient system, suited to the weight of the load. Any lifting and transport operations must be accomplished by skilled personnel, adequately trained on working procedures and safety rules. Instructions in this Manual shall have to be followed when handling the exchanger. Based on their weight and dimensions, heaters can be lifted with lift trucks or wheel-mounted crane. In the first case, use fork extensions as long as heater width. Pay attention to dampers, in installed on the heater. 8 code HG GB ed.c-1509 rev.05

10 3. TECHNICAL FEATURES 3.1 Main Components Warm air heaters include: stainless steel heat exchanger frame and body centrifugal fan and electrical motor control panel and settings safety controls Stainless steel heat exchanger The leading-edge design of furnace and heat exchanger and their wide surface guarantee optimum efficiency and durability. Furnace and flue collectors are entirely built with stainless steel (AISI 430), while contact surfaces (tube bundle) are made of steel with low carbon content (AISI 441), thus guaranteeing higher resistance to corrosion. Tube bundle design is patented (# MI94U00260, April 8, 1994). Characteristics of steel types used The following table shows naming correspondence and chemical composition of steel types used in exchanger manufacturing: USA -AISI EN - N Composition AISI X6 Cr17 AISI X2 CrTiNb 18 The heat exchanger can be used also in presence of condensation. In this case, suitable accessories must be provided and the coupled burner can only burn gaseous fuel. Frame and body The frame consists of solid anodised aluminum bars. The frame is a multi-piece assembly and can be fully disassembled, if required. Body panels are formed by: - On the exchanger side: double-layered panels with inner galvanized steel sheet, high-density glass fiber insulation, external painted galvanized steel sheet. The three layers are riveted to allow safe removal or the panel during maintenance. - On the fan side: painted galvanized steel sheet with inner layer for thermal and sound isolation, securely fastened to steel panel. All panels are gasketed to ensure perfect sealing. Centrifugal Fan Standard centrifugal fans installed are made of galvanized steel sheet with forward curved blades and low noise of operation. Fans rotate on autoaligned sealed ball bearings, isolated in rubber buffers. Two types of fan are used: Fans for rectangular duct: driven by means of fixed diameter pulleys and belts, three-phase motor, models up to PKE250N-P00. Fans for square duct: same as previous, they are used on heaters from PKE320N-P00 upward. No lubrication is required on standard fans. For special fans, check specific requirements. Running Temperatures: - belt drive -20 C +85 C The following fans are available on demand: backward curved blades plug fan, directly driven by the motor and controlled through inverter fans for temperatures lower than -20 C Electrical motor All motors used have the following characteristics: Supply 400Vac - 3-phase - 50 Hz Structure B3 - with terminal board above Protection degree IP55 Isolation level cl.f Efficiency IE2 For more model-related information on motors, see further in this Manual.

17 4. USER S INSTRUCTIONS IMPORTANT: Read Safety Warning on pages 3-4 to discover useful information on how to safely use your equipment. User's operations on the heater are limited to regulating controls on room thermostat (optional). Installation of a room thermostat on a heating system is mandatory. A scheduler can be included in room thermostat. Control Panel The following controls and/or alerts are available on control panel: IG C1 L1 L2 L3 Door lock - On Ø (zero), the whole unit is powered off. Summer/0/Winter switch - It allows choosing the running mode you want. Green lamp - If lit, the control panel is powered. Red lamp - Safety thermostat or fire damper, if installed, has triggered. The user has to manually reset devices. Yellow lamp - The electrical protector of the motor has triggered. The user has to open the control panel and manually reset the device. This feature is installed (but not used) on heaters with single phase supply. Thermostats Heaters include a double thermostat formed by: STB Safety thermostat - When activated, it immediately stops the burner and issues an alert (red light on control panel). Reset is manual (see figure). TW: The thermostat TW is located in the thermostat series of the burner and intervenes, on switching off the burner, when the temperature inside the generator exceeds the calibration value. The thermostat TW is similar to a safety device and must not be used as a regulation thermostat. TR: Fan ON/OFF thermostat - It delays starting the fan with respect to burner start up, thus avoiding blowing cold air into the room. When turning the system off, the fan is stopped after the burner, so it can cool down the exchanger. OPERATION MODES Summer In Summer mode, only the fan works to ventilate the room. The user must start up and turn off the burner manually. Winter In Winter mode, the burner and the fan are started, to blow warm air into the room. Room thermostat makes the burner start and, when the temperature set on TR thermostat is reached, fans are started. Standard contactor for fan motor control is self-holding. This prevents that during start-up, cold air flows cool down TR thermostat and keep stopping the fan. Whet set room temperature is reached, the room thermostat stops the burner. The fan keeps working until room temperature lowers below TR (FAN) thermostat value. During cooling, the fan may be re-started if air temperature inside the heater increases because of the exchanger temperature. The burner restarts when a heat request is issued by room thermostat. If C1 switch is turned on 0 (zero), the heater continues to be powered and fans keep cooling the exchanger, provided that TR thermostat is closed. In these conditions, DO NOT execute any maintenance nor other operation on the heater since fans can restart when the heater is powered. STB SAFETY THERMOSTAT DO NOT power off the heater while it is running because this would prevent the heat exchanger from being cooled down, thereby reducing its life and jeopardising its efficiency. The STB safety thermostat triggers to stop the heater when abnormal overheat occurs. In order to reset it, push RESET command. This thermostat triggers in exceptional conditions, thus revealing a fault. This may be caused by several reasons: a surplus of heat input because the burner has been wrongly set up, insufficient air flow because air grids and filters are clogged, wrong pipe sizing, or wrong fan rotation. If, after multiple reset attempts, the problem continues, turn IG switch to 0 (OFF) and contact APEN Group s Service Center. REMARK: Heaters working in air domes must guarantee continuous ventilation. See pages for wiring instructions. RESET COMMAND PRESS TO UN- LOCK LIMIT THERMOSTAT (STB) 17 code HG GB ed.c-1509 rev.05

Only specifically trained personnel can service the unit. If any abnormal noise is heard during operation, contact your Service Centre. At the end of any repairing or maintenance call by technical service, a dated and signed report shall be issued. The report shall be filed with other documents concerning the equipment. If the system is left unused for a long period, turn IG main switch IG on 0 (OFF) and shut fuel supply valve. If a failure and/or ill functioning occurs, switch off the heater and do not attempt to repair it yourselves. Contact your Service Center. Any repair shall be executed by trained personnel, approved by burner s manufacturer. Failure to follow above instructions could compromise the safety of burner and heater. 18 code HG GB ed.c-1509 rev.05

19 5. INSTRUCTIONS TO THE INSTALLER 5.1 Where to install the heater The place of installation shall be chosen by the project manager or by an expert, considering technical and regulatory requirements in the country the unit is installed. Generally, specific authorizations are required. Therefore, before installing the heater, check that all authorizations are available or have them issued. Install the heater on a flat surface that can firmly and safely bear the weight. Minimum safety distance for correct air circulation shall be kept all around the unit. This will also ease maintenance and control operations. Fuel and power supplies shall be easily accessible. Any wiring and assembling tasks shall be executed by adequately trained and qualified personnel. The heater SHALL NOT be modified in ANY part without the manufacturer s written authorization. Connecting Air Ductwork Ducts for air delivery and intake shall be sized based on aeraulic performance of the unit (shown in Technical Data section of this Manual). A vibration damping joint should be installed on air delivery duct so as to prevent vibration transmission from the heater to ductwork. Special attention should be paid to comply with noise level standards. If required, a sound absorber shall be installed in air delivery ductwork. Connecting Fuel Supply Fuel connection shall be performed by qualified personnel only. Follow instructions in User Manual of the burner installed on the heater and comply with existing regulations. Proper installation requires that a net or another device is installed to avoid reduction of the canal size during operation. HG0150 C code HG GB ed.c-1509 rev.05

20 5.2 Power Wiring Warm air heaters come with a main switch with door lock (IG) shown in the figure. Wire power supply directly to that switch. Supply of all PK-SPORT heaters is 3-phase 400V +N. Wiring is as follows: CABLES Use flexible, flame-retardant, double-coating cables for the wiring. Cable section must be suited to heater absorption and to the distance between heater and connection point. Threephase 400V+N Wire three phases to T1, T2, and T3 terminals and Neutral to N terminal FOR both types ground wire is mandatory. Connect it to relevant terminal. Note: In order to access terminals, unscrew white cover on the upper part of the switch. When finished, reinstall protection cover. Electrical Protections Model PKE Rated current In Breakaway starting current Is/In Wire diameter mm 2 100/ x / x /320* x * x * x Notes: Determine cable section in compliance with EN and IEC /20001 specifications; PVC insulation; room temperature 30 C; surface temperature <70 C; length below 20m. Rated current: current absorbed by gas or gas oil burner. Add ground cable to the number of cables. * Models with soft starter: Breakaway starting current depends on soft starter settings. A protection CHECKS All APEN GROUP heaters undergo severe electrical and safety tests. At first start up of three-phase models, the following checks are mandatory: - Fan rotation sense. If two fans are installed, both have to be checked. - Actual absorption of each motor. It must be lower than rated absorption (see values in Technical Data section). - Adjust trigger threshold of thermal relay to the absorption measured. Increase value by 5-10% over measured value. Never exceed motor rated value. N T1 T2 T3 IMPORTANT: A main switch must be installed before the control panel of the heater. This switch must include a protection (fuses or automatic) and must comply with existing regulations. Fuse type, if used, must be rapid. If automatic switch are used, the characteristic curve for their triggering must be of type "K" or D" or "C". Automatic switches with "A" or "B" trigger curve are not allowed since they are not suitable for electrical motor protection. 20 code HG GB ed.c-1509 rev.05

21 5.3 Electrical Wiring All control panels of PK-SPORT heaters include a wiring electronic card that allows to easily and safely connect common components such as: Fire Damper Room thermostat, timer, and high/low flame control of the burner, if installed. Fire Damper Wire microswitch (NC contact with activated damper) to terminals 51 and 52 of CN6 connector on the heater control card. If microswitch triggers, the burner stops while the fan keeps working to cool down the exchanger. Heat in excess will be dispersed through a discharge shutter. When the heater is installed outdoor and no shutter is installed, and if the fan needs to be stopped, install a relay that powers off fan motor. High/Low Flame Control Wire this control to terminals 43, 44, and 45 of CN7 connector of heater control card. Timer Wire timer contact in series with room thermostat to terminals 41 and 42 of CN7 connector of heater control card. The timer starts the burner at scheduled time intervals. Room Thermostat Wire room thermostat to terminals 41 and 42 of CN7 connector on the heater control card. This thermostat starts the burner only when room temperature lowers under set value. KG0100 C TIMER ROOM THERMOSTAT HIGH/LOW REGULATOR SRV Expulsion damper servomotor FIREPROOF DAMPER LOW HI HG0150 C2 007 Important: If no fire damper is installed, create a jumper on terminals 51, 52 of CN6 connector. The installation of a room thermostat is mandatory. The burner works only if terminals 41 & 42 are closed. High/low flame wiring is required only if a two-stage burner is installed. If you have no two-stage regulator but do have a two-stage burner, create a jumper on 43, 44 terminals of CN7 connector. 21 code HG GB ed.c-1509 rev.05

22 5.4 Wiring the Burner A specific connector (CN2) on wiring card is dedicated to connecting the burner. CN2 connector shows standard numbering for one- or two-stage burners. You only need to wire the burner respecting numbering. If burner terminal board is not standard, do the wiring as follows: Line - 230V Thermostat series Lock signal Operation burner* High/low flame From terminals L1, N From terminals T1 and T2 To terminal S3 To terminal B4 To terminals T6 (common), T7 (low flame), T8 (high flame) * If no connection is provided for burner operation, the selfholding function of the fan is not enabled. Therefore, at start-up or when room air is cold, the fan could repeat multiple ON/ OFF cycles. Three-phase Burner On control panels of models from PKA/E 250N onward, an automatic switch is installed that controls 3-phase burner power supply. 3-phase burners always have two supplies: - 400V Three-phase for electrical motor - 230V single-phase for the control section. With 3-phase motors, remember to verify that rotation sense of burner motor is correct. Connection point of 3-phase motors is under the switch. The installed switch has the following characteristics: Magnetic protection 6,3 A Unlatch current 78 A Breaking capacity 100 KVA X3 X7 X4 Legend of burner plug X7 7-pole plug for burner connection: L1 supply (230V); T ground; N neutral; T1,T2 series of thermostats; S3 lock signal; B4 ON signal; X4 4 pole plus for high/low flame connection: B5 High flame lit signal; T6,T7,T8 high/low flame thermostat.

23 5.5 Continuous ventilation In the case of combining generators with pressure switch structures which require continuous ventilation to support the structure it is necessary to bridge terminals 7-8 of the terminal block CN5 on the wiring board contained in the electrical panel. Bridging these contacts inhibits the FAN function of the thermostats TR (see thermostat connections page 41) 5.6 Emergency. In the case of combing the generators with plants that require the use of UPS systems it is possible to use contacts available on the KM1 remote switch inside the electrical panel to sustain the structure. When the thermal protection of the KM1 is triggered the contact between the terminals (NO) closes while the contact between the terminals (NC) opens.

26 FIRE DAMPER KIT The fire damper kits can be installed at the inlet or delivery since the dimensions of its sections are identical. The fire dampers consist of a galvanised iron plate structure, partition blade and seal and the blade closure device. All the fire dampers have the following characteristics: - Reaction to fire EI120S - thermal breaker with fuse calibrated to 72 C; - microswitch, IP55, supplied as a standard component and installed on the damper - the dampers are supplied with certificate. HG0150 C3 005 HG0150 C3 005 The dampers which are 800 mm high have a single blade (PKE ), while those more than 800 mm in height have a double blade (PKE420/550). The damper, when open, is as deep as the blade is high: dampers higher than 510 protrude from both sides by an amount equal to the height minus the depth (510 mm for all models) divided by two. In the single blade dampers of height 800 mm the blade protrudes from both sides by 145 mm, and for 1,070 double blade dampers the blade protrudes 25 mm on each side. Fire damper kits, when necessary, are supplied complete with spacer bar (length L) to allow installation between the fire damper and generator or shutter. The geometry of the round square fitting kit always makes it possible to install the latter downstream from the fire damper while for all other types of installation and spacer bar of length "L" is required downstream from the fire damper in order to allow the blade to rotate completely.

INSTALLATION OF THE FIRE DAMPER ON A RIGID WALL HG0150_C3_ make a hole in the wall having a base and height 85 mm larger than the nominal measurements of the damper; for walls constructed in concrete blocks or bricks it is advisable to insert a reinforcing lintel above the opening; 2. insert the damper in the opening so that the anchoring flange rests on the surface of the wall; 3. anchor the damper to the wall using the holes in the anchoring flange using self-threading screws or expansion bolts of diameter 6 mm; For further information see the manual enclosed with the dampers. 26 code HG GB ed.c-1509 rev.05

27 USE OF THE FIRE DAMPER To set the damper turn the control lever anticlockwise. To release the damper press the button shown in the figure. IMPORTANT: make sure that you do not turn the lever energetically in the wrong direction as this could break the closure device. IMPORTANT: After installation check that there are no obstructions to the correct rotation of the blade. FUME EXPULSION DAMPER KIT The fume expulsion dampers are used in combination with the fire damper kit and make it possible to expel fumes outside the generator. The wings, connected to each other by internal levers are held in the closed position by a servomotor powered electrically from the wiring board (see electrical connections on page 24). In the case that the fire damper is triggered the servomotor forces the wings to open the damper rapidly. The frame and wings are made of extruded aluminium.

28 SERVOCOMMANDS FOR AIR DAMPERS The air damper supplied can be motorized but comes with no control. The following control kits are available: - Manual control - Servomotor for ON/OFF control(230v) - Servocontrol for modulating control 0-10 Vdc (24V) If a motor-assisted control is installed, a control is needed in addition to servomotor. This control can be of the following types: ON-OFF - You can control ON-OFF models using a simple switch that opens or closes the shutter. Mechanical stops can be used to reduce the range. Modulating - Modulating controls need a controller that regulates the shutter based on the output (0-10 Vdc signal) from a value such as temperature, humidity, air flow rate, and so on. As an alternative, you can also use a potentiometer (0-10 Vdc), to manually set the shutter based on your needs. Modulating servomotors require 24V supply while ON/OFF servomotors need 230V supply. Servomotor: This picture is for reference only. Brand and model of supplied device can change without notice.

29 INVERTER Special applications that require variable air flow rates can also be met by supplying heaters with fan control through inverter. Using an inverter requires an understanding of its control system. Available control types are the following: A B C Speed selector: from 2 to 8 default speeds that can be selected through an electrical switch or a potentiometer. Modulation control using an external signal (generally 0-10V or 4-20 ma). Control of a variable (air pressure, temperature or other) A - Control through a speed selector It s the easiest. It is manually operated by the user and/or electrically operated through free contacts of a relay or other device. Default speeds can be modified by the user. Another option is to use a resistive potentiometer: the shift is within a minimum and a maximum set values. B - Modulation control Before the inverter, a controller sends an analogue signal to the inverter based on the value to be monitored (pressure, temperature, other). The inverter varies its speed according to the input received within max and min values set. C - Control of a variable Almost identical to B. The only difference is that the inverter can directly regulate the monitored variable: its values, its max and min values can be directly programmed and managed through the inverter. For this configuration, a sensor is required to monitor the variable. Inverters can be useful for the following applications: - Installations where pressure drop is unknown or difficult to calculate. During installation it is possible to fine tune air flow rate. - Buildings where set temperature should be rapidly reached, in order to reduce speed and minimize noise. - Variable air flow rate: multi-area air distribution systems where each area has its own temperature setting. - Air supported structures and domes: this method maintains optimum pressure value within the dome (supported by a wind speed sensor) and consistently reduces electrical consumption. NOTES: - With standard motors, minimum speed must be higher than 22 Hz to guarantee cooling down motor coil. If this threshold is too high, special motors are available and can be requested to APEN GROUP Technical Support. - The main switch protecting the heater through an inverter must have a residual current to the ground of 0,3A (300 milliampere). Switches with residual current of 0.03A (30 milliampere) are not suitable. Note: If motors including an inverter are used, it is mandatory to install a two-stage or modulating burner with flame mode control depending on fan speed. Inverter: This picture is for reference only. Brand and model of supplied device can change without notice. 29 code HG GB ed.c-1509 rev.05

30 SOFT STARTER APEN supplies soft starters as a standard for motors with an output equal or higher than 5.5 kw. Soft starter has the following advantages: - In installations where air distribution ducts are made of textiles (or similar), it prevents the initial splash effect and guarantees longer life to ducts. - It balances motor breakaway starting current - It helps reducing belt wear and extending the life of motor and fan bearings. A soft starter for 3-phase motors with capacity below 5.5 kw is also available. G soft starter for motors up to 2.2 kw G soft starter for motors up to 4.0 kw Power ON lamp End of cycle lamp Start up time Default=C Start-up voltage Default=C Room Thermostat Setting ON/OFF G11280 G11280 kit includes an electronic room thermostat equipped with NTC temperature sensor.

31 TEMPERATURE SETTING G09921 A digital electronic regulator is available to control air temperature. The regulator is delivered already wired and tested on front of control panel. It includes a room sensor or a duct probe, based on installation. This regulator can only be used matched to a two-stage burner. Both delivery and intake room temperatures can be checked. Modifying Set Point To change set point 1 (Default =20 C): Press SET key: the screen displays ST1, then the current value of ST1; Press UP and DOWN keys to modify the value; Press SET again to confirm new ST1 value. The following sensors or probes can be matched to the regulator: Code Features Temperature range G07202 NTC - Room sensor -10 C to 60 C G07203 NTC - Duct probe -10 C to 90 C G17675 NTC - Wire probe -50 C to 105 C G16170 PT100 - Ø6x C to 450 C G16195 PT100 - Ø6x C to 450 C Settings: The following parameters must be set: ST1 (set point) and P1 (tolerance). The regulator operates 1st stage (ON-OFF Burner) or 2nd stage (high/low flame burner) depending on how far set point is. Example: ST1=20 C P1=2 C Cold room to be heated: up to 19 C burner is ON with high flame, between 19 C and 20 C burner is ON with low flame, over 20 C burner is OFF. Warm room cooling down: below 19 C burner turns ON with low flame, below 18 C burner turns to high flame. You can get the operation you need by changing ST1 and P1 values. If probe is on delivery, set ST1= C and P1=3-5 C. ST2 set point and P2 range are not used. Process plant installations can require fine tuning P1 range asymmetrically with reference to set point. In such case, contact APEN GROUP Technical Support.

37 ACCESSORIES FOR CONDENSATE HANDLING If a heater with modulating and/or two-stage burner is installed, high air flow rates and low heat drop can result in condensate production. It is necessary to drain this condensate from the exchanger using a suitable system. All PKE-N-SPORT heaters include a kit for condensate drain. No condensate should form into front manifold because the gaskets installed are not waterproof. In order to avoid this, burner heat input should be adjusted to a value at least equal to heater minimum heat input (see table with technical data). If condensation is not drained from the exchanger, it could seriously damage it. The warranty of the exchanger does not cover damages caused by condensate. The picture below shows examples of horizontal and vertical installation. In both cases, it is better to install the exchanger with a slight inclination in order to ease the drain. Standard installation of condensate drain has its outlet on chimney side. Materials to be used for condensate drain Any plastics should be avoided for condensate drain system since flue temperature is too high. Suitable materials are stainless steel and aluminum (only outside the heater). Galvanized steel is not recommended since it can be corroded by acid condensate. This kit is identified by code G00740-xxx-V Replace xxx with heater size code. REMARK: in PKE-K heaters, front condensate drain is built-in. IF AN OIL BURNER IS MATCHED, IT IS MANDATORY TO PREVENT ANY CONDENSATE. VERTICAL CONDENSATE DRAIN ON THE BACK Draining using a Siphon [G14551] If the heater is installed indoor and a condensate drain system is provided, the siphon must be smoke proof. The siphon includes a float that prevents any flue leaks, even when the siphon is empty. Fill manually the siphon with water at first start-up. KIT G14303 Apen can supply a kit for deacidifying acid condensate. This kit is suitable for heaters of any size. 37 code HG GB ed.c-1509 rev.05

40 THERMOSTAT WIRING - CONNECTOR CN5 The PKE-P00 is fitted with two thermostat units: the triple thermostat TR+TW+STB, located in the top part of the generator inside the burner cavity, and the dual thermostat TW + TR in the delivery. STB: The STB thermostat or Limit switch, (safety thermostat with manual reset) stops the burner if an excessively high temperature for the heat exchanger is reached; if the STB is triggered it is necessary to reset the thermostat manually following the procedures explained in the user section of this manual. The thermostat acts on the KAS relay of the wiring board cutting off the voltage to the burner. TW: The TW thermostat is located in the series of burner thermostats (T1 - T2) and acts by switching off the burner when the inside the generator exceeds the calibration value. The TW thermostat is similar to a safety device and must not be used as a regulation thermostat. TR: The TR thermostat allows the fan to start only when the air reaches the temperature set. When the burner is switched off it allows the exchanger to cool down. The three thermostats installed inside the box are calibrated to the following temperature values: the TR is set to 40 C; the TW is set to 90 C; the STB is set permanently to 100 C. To adjust the settings of the TR and TW thermostats turn the relative screws. STB + TW + TR TW + TR THERMOSTATS ON DELIVERY HG0150_C3_012 The dual thermostat TW+TR located in the delivery line of the generator can be adjusted by opening the box that contains the thermostats and turning the screw with a screwdriver. The TW thermostat is set to 65 C and, being connected in series with the TW thermostat of the triple thermostat, acts by switching off the burner to prevent triggering the fire damper.

44 6.2 Burner Matching The burner nosepiece must penetrate for a length not exceeding min and max values of X. Important. Nosepiece length must be greater than "X" min value. Shorter nosepieces could damage the exchanger and void the guarantee. The value of ØT indicates maximum nosepiece diameter for a specific heater. If the installed nosepiece is larger, the exchanger will have to be changed at an extra cost. Contact Apen Group Customer Service if you need to use a low NOx rate burner with flue gas recirculation outside the combustion head. Standard heaters supplied include standard burner plates sized as shown in the table below. If standard burner plate is not suitable for the burner to be installed, a plate with custom holes can be ordered (specify burner brand and model).

45 6.3 Gasoil Burners If a gasoil burner is used, its heat output depends on: Nozzle size Burner pump pressure. The table below shows the nozzles and pressures allowed for each heater model. For each nozzle, heat output (kw) and consumption (kg/h) values are reported with reference to pressure. To calculate consumption in litre/hour, just multiply the kg/h value * 1.14 [density = 0.87 kg/l]. If a two-stage burner is used, the sum of the two nozzles is reported in the table. First stage nozzle cannot be smaller than the nozzle listed in first column. This is to avoid condensate in flue. Condensate in flue is not allowed for oil burner. The use of nozzles with spray angle of 60 or 80 is mandatory. It is forbidden to use nozzles with an angle of 45 both on first and second stage. Table for nozzle-heater matching.

47 6.5 Burner Matching Tables In the following pages burner matching between PK-SPORT heaters and gas burners by main European manufacturers are listed. Please remember that any burner must be accompanied by an EC certificate valid for the Country it is destined to; it must be certified for the gas type that is going to be used and accompanied by localized documentation. Oil burners are listed in APEN GROUP column. Some burner models are undersized if compared to maximum heat input of matching exchanger. Please, always check data supplied by burner manufacturer. Remember that burner nosepiece length must always be the one indicated in table on page 51, and that the heat output set must be lower than heater maximum heat input.

49 7. MAINTENANCE 7.1 Controls at First Start Up Before / during first start-up, the following items need to be checked: Electrical Checks Supply voltage Fan rotation direction Motor absorption and air flow rate Combustion Checks Length of burner nosepiece Fuel capacity of the burner Combustion parameters Safety Checks Check if STB+TG or LIMIT safety thermostat triggers Microswitch for fires dampers (if installed) Room thermostat TR or FAN thermostat Electrical Controls Before powering the unit on, make sure actual voltage matches the rated voltage specified. In 3-phase units it is mandatory to check fan rotation direction. If the heater has two fans, check both rotate in the required direction. Verify each motor s absorption with a suitable amperometric analyzer. The table on page 26 shows maximum absorption values for each heater. The table on page 59 shows absorption values for each motor. An absorption rate lower (<15%) than max value means that air flow rate is lower than rated. If necessary, restore air flow rate by changing one of the pulleys to increase number of fan revs or by reducing pressure drops in air distribution system. A higher absorption than rated value means that aeraulic circuit resistance is lower than expected. To restore rated value, local pressure drops should be created to reduce electrical absorption by the motors. Combustion Check We recommend checking that burner nosepiece is suitable for use (see relevant paragraph) A fuel capacity check must be performed: - At the meter, in case of a gas burner - By comparing nozzle capacity/pressure with values in specific tables, in case of a oil burner. When fuel capacity cannot be measured, adjust the burner by checking combustion parameters. Reference values for CO 2 content and therefore for O 2 excess air for different fuels are listed below: Flue temperature is to be measured to set thermal output after combustion has been adjusted. Nominal heat output is reached when net flue temperature ranges from 392 to 428 F (200 to 220 C); maximum output is reached when net flue temperature ranges from 518 to 554 F (270 to 290 C); and minimum output is reached when net flue temperature ranges from 248 to 284 F (120 to 140 C). During first start up, the following checks are recommended: If combustion efficiency is known and CO 2 content is included in the above range, check in charts on page 9 the useful heat "set" for the heater. Checks on Safety Controls All heaters and their safety devices have been electrically tested before delivery. However, their correct operation depends on how they are actually wired and installed. When first starting the appliance, the following controls must be performed: STB + TW Safety thermostat Lower the value of TW until the burner is switched off then reset the value of TW. To verify the action of the STB it is necessary to disconnect the thermostat electrically and check that the burner switches off and the red light comes on. After testing make sure that the thermostat is reconnected correctly. Fire Dampers If fire dampers are installed, you need to check that its closure actually stops the burner. A red lamp indicates that the damper has triggered. Room Thermostat Check that room thermostat and/or the timer turn off ONLY the burner, not the cooling fan. The fan shall stop only when the exchanger has cooled down. TR or FAN Thermostat Make sure the thermostat starts the fan on time, before the safety thermostat triggers, and that it prevents blowing cold air from louvers at turn off. Control on delivered air temperature. Make sure that temperature of delivered air does not exceed 65 C and that there is no danger that safety devices trigger while the heating is normally operating. Natural gas CO 2 content 9.7% ± 0.2 L.P.G CO 2 content 10.2% ± 0.2 Fuel oil CO 2 content 12.5% ± 0.3 CO 2 values shown can surely be improved without producing unburnt products. However a high quantity of excess air should be maintained in order to balance possible working variations in time. 49 code HG GB ed.c-1509 rev.05

50 7.2 Routine Maintenance We recommend execute maintenance operations using the following schedule: Air Filter Belts Electrical motor Fan Combustion Analysis Safety Thermostat Fire Damper Cleaning the Exchanger Clean it every 30 days After 8 hours from first start-up. Then, every 60 days. Check electrical absorption every 90 days Check cleaning every 90 days Once per season At the beginning of each season At the beginning of each season See paragraph By using a pressure regulator for the filters, an air flow switch or similar controls, you can check air filter and belts every 90 days. Checking Transmission Belts About 7 8 hours after first start up, check tension and state of belts between motor and fan. If belts are loose, stretch them. To check correct belt tensioning, verify that in the central area between pulleys, belt oscillation does not exceed 20 30mm. To tension belts and align pulleys, adjust belt tightener screws. Turn clockwise to tighten and counter-clockwise to loose. During this operation, verify if pulleys are aligned using a rod long enough to join the pulleys. Checking the Cleanliness of the Exchanger Correct operation and long life of the exchanger depend on its design but also on proper maintenance. The following checks must be performed at regular intervals: - Check of burner combustion - Check of safety device operation - Visual inspection of the exchanger - Check that heat exchanger is clean Controlling burner combustion values Check at least once a year burner combustion values. Parameters to check are CO2 content, flue temperature and C0 value. Note these values at first start up and at every subsequent maintenance check. If consistent changes occur, investigate on the causes. For oil and LPG burners, also smoke density must be analyzed. The test should return a value below 2 on Bacharach scale. An increase in smoke density value would require cleaning the exchanger. Checking Safety Device Status Check every year that safety devices are working properly. See procedures to follow in the page next to "Safety Controls section. Inspecting the exchanger Inspect every year the exchanger to make sure no component is overheated and/or damaged. If you see any overheated areas, investigate on possible causes: - Insufficient or badly distributed ventilation - Dirty air filters - Partially closed dampers - Burner capacity higher than exchanger specifications If any of the exchanger parts is damaged, it should be replaced and the cause of the damage removed. KG0100 C3 030 Cleaning the Exchanger It s hard to specify the period after which the exchanger must be cleaned. A safe method is to note the pressure value in the furnace at first start up, after completing all burner settings. Near the peep-hole, a tapping point is available to make this measure. The resulting value already includes pressure drops in the chimney, if any. Repeat this measure every year during combustion check and compare the result with the initial value: if they differ by more than 35%, the exchanger is to be cleaned. Generally, if natural gas burners are installed, cleaning is not required for 5-6 years. If burners are fuelled with oil and/or LPG, the cleaning should occur every 3 years. 50 code HG GB ed.c-1509 rev.05
