4 Security instructions Installation regulation A B C D E F The exhaust fumes must be conducted into the open through a chimney or flue approved for oil or gas heating appliances and in acoordance with all applicable standards. The chimney can be in masonry or metal The opening of the chimney must clear the roof by at least 1 m, and the roof ridge by at least 0,5 m. It must be expo-sed to the free wind conditions. The opening of the chimney must not be in the vicinity of a window or a balcony. Temperature of exhaust fumes When setting into operation and adjusting, set temperature of exhaust fumes for at least 160 C. Installation of flue pipes A catch elbow must be connected to the flue connector for rain-water condesation Horizontally installed flue pipes (max.1/3 of total flue pipe length) must have a continuous gradient of 2cm per metre. Flue pipes must be interconnected in the direction of the draft. Installation or the pipe system Pay attention to the maximum pressure. If this exceeded, the air volume of the fan will fall and both the flue gas and warm air temperature will rise. Ventilation Sufficient air for combustion must be available (avoid low pressure in the installation room). This is assured when: e.g. the volume of the room in m³ is a minimum of 10 times the rated heat load in kw of all the heating appliances in the room. Normal circulation is to be guaranteed via windows and doors. If low pressure or dust in the room air are not avoidable, the burner must be encased and the air supply taken from outside the room. Warning The space heater is only to be installed on combustible floor. An area of 1 m around the heater is to be kept clear to ensure an unobstructed flow of air to and from the heater. Do not switch off electrical supply and main switch until the space heater has cooled down. Non-compliance invalidates the factory guarantee. 4

5 Whe run with gas, the flue pipe must be put into the flue outlet by means of an adapter pipe. 5

6 Description Warm air heaters, type S, are direct-fired and highly variable units. In contrary to other heating systems they can be installed inside the room. The devices are made exclusively for industrial use in halls and large capacities of each kind, especially in locations where heat is immediately needed. The warm air heaters (S) are made of high-quality material and are manufactured clean cut. Thus they guarantee trouble-free operation and durability. Special attention is given to a simple and quick installation and ease of servicing. The case is constructed as solid galvanized framework. The double-shelly screwed panel consists of 1 mm galvanized steel sheet - inside and outside. Due to the framework construction and the removable panels, the warm air heaters can be dismounted. Radiator: The combustion chamber is made of chrome-alloyed, high-heat resistance stainless steel. The tubular heat exchanger is made of standard steel with baffle. Combustion chamber and heat exchanger a re screwed via a flanged joint. Thus the whole unit can easily be decomposed in two pieces. Therefore it can be set up quickly in small rooms, replaced or partly-renewed without any problems. Upon request the heat exchanger can be delivered in stainless steel with condensate nozzle (extra price). Fan : In the bottom part, silent tangential fans and maintenance-free ball bearing are mounted. Driving is made via a three-phase standard motor with V-belt-drive. All units are standard equipped with a switch box and a fan-burner and a safety thermostat. The plenums are open to three sides with horizontal air conduction lamellas. Upon request and extra price, further plenum solutions or a ductwork can be delivered. General information: As to the installation of the units, the respective security specifications and directives of each country have to be respected. The decrees for carrying out the Immissions Security Regulation and according to this the enacted legal decrees have to be observed as described in your country. Only tested oil burners in warm air heater-type or gas burners may be used. In case of ex factory delivered units incl. oil- or gas burner the separately additional working instructions have to be observed. Pay special attention: - To the list guidelines of warm air heaters - To the general safety-relevant requirements - To set up and operate according to your countries regulations - Fuel supply according to your countries regulations - Technical rules for gas installation according to your countries regulations - the VDE - regulations - Warm air heaters are as fire places in principle permission and indicate requiring. - consider the rules for the prevention of accidents and other safety-relevant regulations and guidelines 6

7 Installation notices Suction of combustion air As to the installation of the units, the respective security specifications and directives of each country have to be respected. Place of installation Before installation the following requirements have to be proved: a) fire protection b) function (e.g. room heating, with plenum or duct system, negative or overpressure...) c) specific requirements as heat demand, air delivery, ambient or outer air demand, room temperature, air diffusion, space capacities) d) connection to the chimney e) installation, repair and maintenance possibilities f) relation room volume - rated heating power, especially in naturally ventilated rooms. A sufficient natural air delivery, necessary for the combustion, means e.g. that the room volume in m ³ is equivalent to the tenfold rated heat load in kw of all heating units in the room and that windows and doors assure a natural ventilation. Good and natural ventilation means e.g. 1. the room volume in m ³ is equivalent to the 30fold rated heat load of all heating units in the room and windows and doors assure natural ventilation 2. the room offers openings near floor and ceilings which cannot be locked-up, corresponding to 0,003 fold rated heat load in kw of all units in the room. Suction of combustion air The combustion air should be free of each kind of pollutants. - If - due to production conditions - pollutants (e.g. chloride, CKW, FKCW etc.) comes to the warm air heater, the combustion air for the burner should be taken from outside and a burner casing (see accessories) has to be used. The influx of enough combustion air is guaranteed when suction from: - installation room, if this meets the requirements to the volume-rated heating efficiency ratio of the construction supervision ( 4 m 3 / kw ); installation room, if this is heated by the warm air heater outside air- or secondary air-driven with guaranteed outside air rate; a fixed room power ratio is not necessary; - installation room, with not lock up openings outwards, according to the requirements of the construction supervision; - outwards, through a pipe connected with the burner/heater or its housing whose profile is big enough it must be adapted to the available free air capacity of the burner/heater and the line resistance (including the suction protective grating), that an efficient combustion is guaranteed. 7

8 Assembly indications / Starting up For installation of the apparatus you have to follow the regulations and decrees of each country. The apparatus are suitable for the use of suck in- and blow out-attachments. It has to be guaranteed, that the fan power (nominal pressure) is adapted according to each air-side resistance (test rated current) The apparatus are not suitable fort he excluding use as induction system. - The apparatus have to be installed steadfast. - Pallet or wooden frame have to be removed before installation. - In case of installation on the ground the apparatus should better be installed on a separate foundation free of tension and secure. - The suction of air may only occur according to the suction port. When the bottom of the apparatus is not designed as suction variant it has to be closed to avoid infiltrated air suction. - If heavily pollution of the air in the installation room is eventually expected you have to conduct the return air suction through appropriate filter (apparatus accessories). In this connection you have to observe the suck-side resistance and according to this you have to suit the fan power. - You have to guarantee the admission of combustion air. In case of eventually super pressure or low pressure or heavily pollution in the installation room you have to install a burner-fresh-air-suction. Pay attention to a free air suction- and air blow-out possibility. Exhaust connection An exhaust system has to be guaranteed according to the rules. The construction must be according to DIN part 1(construction and mounting of chimneys), the measuring according to DIN 4705 part 1 or part 2 (firing technological calculation of chimney dimension) The exhaust connection must be carried out workmanlike/professional after the valid regulations. Caution: The exhaust connection may only occur on chimneys which are approved before. The chimney draft may maximum amount 0,2 mbar (appropriate:. 20 Pa, 0,2 h Pa), otherwise damages of the radiator will be possible. Pay attention to extreme weather conditions, roof shapes, settings, etc. In doubtful case you have to use a draft regulator. Electric installation The electric instrument connection has to be done by authorised experts after DIN EN and VDE On apparatus with nominal heating efficiency over 50 kw you have to apply an emergency switch on good accessible place outside the installation room. It must be save towards unauthorised operation. The room thermostat (accessories) has to be attached at advantageous place for temperature regulation. The thermostat sensor may not directly be exposed to extremely cold or hot air stream. To install an automatic day/ night temperature regulation you have to operate as described before. The connection of a day/ night temperature regulation or of a room thermostat takes place at the connecting strip inside the control box (watch the circuit diagram inside the control box). Connection of fan motor The apparatus are wired completely in the factory. In case of changes or exchange of motors you have to care about the right motor connection. Doing this you always have to follow the separate attached valid circuit diagram, lying in the switch box. The start of the motors is factory adjusted till 3,0 kw directly in the Y, above 3,0 kw by a Y/ circuit. 8

9 Setting into operation The space heater and burner are controlled by the selector switch and by means of a room thermostat or via control for week program Power connection The electric connection of the machine must be done by authorized personnel according to DINEN (VDE0116-1:2005-3) and DINEN (VDE0700-1).

24 Warm air heater - electric accessories Kroll day/night automatic control (electronic two-point controller) Instruction manual General description: The temperature controller IST with sensor RF-0 is used to control the temperature for general purpose. The operating range is C. The temperature in C can be regulated with two separate adjusting knobs, that are indicated by day and night. At which time periods the ranges day and night should apply, can be programmed by a weekly timer. This timer has got a reserve power of approx. 150 hours. The function of the temperature controller corresponds to a two-point controller. The switching hysteresis can be set between 0,2K and 1,2K. The trimmer P3 is accessible after opening the front cover and removing the front plate. The setting is to be executed by qualified electrical service personnel while the controller is voltage-free. The temperature controller IST is an electric sensor control unit and an independent control unit for assembly and fixed wiring, type X. There is no limitation of operating times. The operating mode is automatic with micro switch-off, type 1. B without sensor-failure-switch-off. With a sensor type RF-o, the controller works in a range of 0 up to 35 C, at a temperature variation speed of approx. 4 K/h and a (low) set switching hysteresis of approx. 0,2 K. The temperature variation speed depends on the characteristics of the other parts of the controlled system like heating load, cooling load, overload of the heater etc. The controller may be operated in polluted areas (IP 54). Putting into operation: Before putting the unit into operation, correct wiring and fixings of the wires are to be examined. By switching on the mains, e.g. by activating the fuse, the controller starts to operate. The switching hysteresis can be set between approx. 0,2 K and 1,2 K. The trimmer P3 is accessible after opening the front cover and removing the front plate. A description of the timer is enclosed. All indications concerning type EM/1 digi 16 without relay output are valid. The timer documentation informs about the setting on time and about how to program the switch-off (page 31 to 38). The information on page 34, paragraph 7, about the accumulator are valid accordingly, since there is one inserted in the controller. Operation: Corresponding to the programmed timer, the temperature is controlled according to the selected temperature set value day or night. Both set values can be selected separately within the limitation from 0 to 35 C The red control light indicates the operating mode of the controller. If it is switched on, the controller has demanded heating, which means that phase L is connected through to output L1 resp. the temperature set value is higher than the actual temperature as measured. Connection: The electric connections of IST are under the cover at the front side of the unit. Note! The unit is to be connected by a registered electrical specialist only. The instructions of the electricity supplier and the specific unit instructions are to be observed. 24

25 Warm air heater - electric accessories The sensor is linked with terminals 17 and 18. Mains and sensor leads are always to be separated by using different case openings. The sensor leads are laid through the outer right opening. They may be extended up to 50 m. In order to do this, a screened cable type LiYCY 2 x 0,5 is to be used. The screen must be put under terminal 18 on one side.

27 Burner - assembly type 140 S 360 S 430 S 730 S C = at least 150 mm 210 mm The burner will be mounted on the front side of the unit with 4 flange screws. In each case the operating manual for the burner has to be respected! Concerning burners of other suppliers: installation is to be made corresponding to suppliers directives. The combustion chamber should not be over- or under loaded. Waste gas temperature should not be under 160 Kelvin over room temperature (condensate). In order to avoid condensates with 2-phase burners they should only be driven in under load during start. The instrument block of the burner is loosely enclosed ad has to be assembled on the site. Installation, gas connection and initial operation have to be made exclusively by specialists. The combustible flow should correspond to the heating power as ordered. The burner has to be adjusted in a way that the combustion chambers load is steady. The flame ends should not touch the back wall! Recommended die approach angle for oil burners is 60. The length of the fire tube X must at least achieve the dimensions C of the following table. It is recommended that the fire tube sticks into the combustion unit about mm. If necessary a fire tube extension is to be used. 27

28 Burner assembly Burner plate The bore for burner fixing are made in the middle of the burner plate and are predrilled corresponding to the following table. Other measures for diameter B and F only upon special request. Mea sure (mm) Type 140S- 360S 430S - 730S A B Ø F Ø M M8 M 10 Electric connection of the burner Kroll Warm air heaters are designed in a way that usually every tested burner brand can be used. It is connected via a rapid assembly plug-and-socket connection (230 V 7-polar) which is attached to the warm air heater. A permanent wiring is made from 3~ 400 V burners on. If burner is provided by customer, the connector plug (enclosed with each burner) for 230 V and for 400 V has to be installed according to circuit diagram. If burner is provided by customer always indicate if it is with 230 V a.c. or with 400 V three-phasemotor and send valid circuit diagram. A fixed wiring takes place from burner type 3 ~ 400 V. Fuel oil connection A sufficient fuel supply has to be guaranteed. The installation of the fuel oil supply has to be done by authorised experts according to the regulations for oil warm air heaters in your country. You must specially pay attention that the cross section of the line will be designed for the complete line resistance, the suction height and an increased viscosity in case of lower temperatures. If necessary a oil feeding aggregate has to be used. The suction pipe has to be supplied with a foot valve in the tank head. Attention! If external temperature is low, enough free-flowing oil has to be at burners disposal. Gas connection Corresponding to the units requirements, the necessary gas quantity and gas pressure always have to be obeyed. The installation of the gas connection has to be done by authorised experts after DIN 4756 or after DVGW-working sheet G 600 for gas fired warm air heaters, as well as the TRF for liquid gas. Gas pressure regulation apparatus and stop cocks has to be prepared on the part of the builder. The power cross section is designed on the base of gas connection, performance resistance and pre-pressure. Before initial operation gas lines have to be cleaned and checked. Exhaust of combustion gas The units have to be connected to an own chimney, steel or bricked. The chimney type has to be according to DIN part 1, the chimney measures according to DIN 4705 part 1 or part 2. For the optimum function of the fire place, the chimneys should be installed near the ridge and overlap this by minimum 0,5 meters. If amming velocity heads (e.g. by katabatic winds or because of buildings in the neighbourhood) are expected. In this case the dimension of the chimney should be correspond to this. Chimneys out of steel will normally be approved as exceptional case, if there are no fire protection considerations. The DIN 1298 is valid for the exhaust gas tube connectors between apparatus and chimney. The connectors should not be longer than 2 meters. The exhaust gas connection has generally to be installed on approved chimneys. The chimneys can be bricked or made of metal. 28

29 Setting into operation fan motor 1.Checking the drive Check fan direction of rotation, watch directional marker at fan box. Check priming of driving belt. Check if fixing bolts of complete drive are screwed up. 2. rated current measure current consumption To avoid incorrect measures, all provided suction- or blind sheets have to be mounted on apparatus and the grille screens in the air channel and in the blowing out hood have to be opened. The existing system voltage has to be checked. a) Direct start The measured rated current (ampere) may not exceed the value given on the motor type plate. Thermally adjust overload relay according to rated current of motor. b) Y/ - start The measured rated current (ampere) may not exceed the value given on the motor type plate. Multiply rated current of motor with factor 0,58 and the thermally adjust overload relay according to calculated value. To avoid errors of measurement, each phase should be measured separately. 3. Thermally overload relay By removing a safety fuse the function of the overload relay or is control value can be checked. In orderly function resp. adjustment the relay should release after about 30 seconds. 4. When charging current consumption is too high If the motor takes up too much current although the electrical connection is done orderly and the voltage supply is sufficient, the thermally over current release must not no account be set higher and it must not be bridged. For remedy the air suction and the air outlet (eventually duct compression) have to be checked. Remedial measures have to be taken. First starting The first starting of the unit and its blowpipe have to be done by the manufacturer or by another expert who is authorised by the manufacturer. Doing this the function and the correct adjustment of all control, regulating- and safety devices have to be checked. - Check all screws and nuts of the fan- and burner fastening are jammed tight. - Check voltage of driving belt.. - If need be, open the out-blow grating and adjust it according to the requirement. - Check the adjustments on triple combination regulator (burner 75 C, fan 45 C) - Switch on the build-laterally main switch/ fuse - Check fan direction of rotation (operating switch in position: ventilation ) - Adjust room thermostats higher than actual room temperature. - Open fuel supply - Operating switch in position heating. CAUTION! After the first 40 running hours in heating operation the screws of the cleaning cover at the radiator as well as the screws of the connecting flange between the combustion chamber and the heat exchanger have to be checked and, if need be, tighten up. Therefor the case cleaning cover above the burner has to be opened. This control has also be done at each regular service. 29

30 Setting into operation fan motor The fuel oil resp. the gas throughput (of a unit) has to be adjusted according to the thermal stress of the unit (watch unit type plate). The burner has to be adjusted according to the producer s data to optimum values, but minimum to those of the Bundes-Immissionsschutzgesetzes BImSchG. The chimney draft has to be measured in cold and warm condition (watch also page 9). To avoid (the danger of) falling below of the point condensation and (out of this) the resulting corrosion in the heat exchanger, the exhaust gas temperature-difference ( /t ) from 160 Kelvin must not be fallen below. The first start up must only be done by authorised personal. A measuring report has to be done and handed over to the operator for keeping! The operator has to be intimated with the unit! Heating - Switch on the build-laterally main switch/ fuse - Open fuel supply - Set operating switch in position heating. - Adjust room thermostats on wished room temperature. In case of heat requirement, the blowpipe switches on itself automatically. The supply air fan won t be switched on until desired temperature has been reached. Doing this you avoid the out blow of cold air. Now the unit works fully automatic according to the desired room temperature. Ventilation Set operating switch in position: ventilation Unit works as permanence ventilation. A thermostatic regulation is not possible Turning off Set operating switch in position: 0 The supply air fan keeps running for cooling the heat exchanger. Until final turning off it can start up several times. Never switch off the unit at the main- or emergency switch before the whole operating sequence of the re-cool phase (except in an emergency). In case of a longer lasting interruption of operation, the build-laterally main switch resp. the fuse should be switched off after the turning off and the fuel supply should be shut off. 30
