6 Description 1 Introduction The ELITEC DTG 1300 Eco.NOx/V boiler is a floor-standing cast iron gas-fired boiler with an atmospheric burner with very low pollutant emission with integrated domestic hot water production. The boiler must only be connected to a chimney. The design of the cast iron heater body with interleaved spurs gives very high performance. Also, the baffling in the smoke circuits limits the natural chimney effect and gives high performance yields. The boilers are equipped with an anti smoke release safety device ; they may therefore be installed in inhabited areas. It consists of a thermostat located in the anti-blowback which causes the burner to stop for 15 minutes. This is indicated by an alarm light flashing on the control panel. The boiler automatically restarts after 15 minutes if the cause of the cut off has been removed. The tightly packed insulation of the boiler equipment reduces losses into the atmosphere to very low levels. 2 Composition of the range Heating and domestic hot water - DTG 1300 Eco.NOx/V or H Panel B: Boiler with (110 ou 130 l) domestic hot water tank and electronic command panel - DTG 1300 Eco.NOx/V or H Panel E: Boiler with (110 ou 130 l) domestic hot water tank and electronic command panel with extractable or built-in Easymatic regulator - DTG 1300 Eco.NOx/V or H Panel D: Heater with (110 ou 130 l) domestic hot water tank and DIEMATIC 3 electronic command panel The command panel gives priority to producing domestic hot water. 3 Certifications 3.1 Introduction 97/23/CE Directive Gas and oil boilers with a maximum operating temperature of 110 C and hot water tanks with a maximum operating pressure of 10 bar pertain to article 3.3 of the directive, and therefore, cannot be CEmarked to certify compliance with the directive 97/23 EC.

10 Installation 1 Implementation The boiler can be installed : - in the kitchen, - in the cellar, - in the boiler house. It is necessary to have in every case : - 5 cm on one of the boiler sides, - 70 cm minimum in front, - and 5 at the rear. Also have the required space for installing the expansion reservoir and the heating circulator. 5 cm from the w 5 cm to the left or right Furniture 1.1 Ventilation The ventilation section, obligatory in the location where the heater is installed where there is a direct air inlet must conform with the DTU 61.1 (P45-204) standard and in particular with the instruction on general management (Book 1764, April 1982). In order to avoid damage to the boilers, it is necessary to prevent the contamination of combustion air by chlorine and/or fluoride compounds, which are particularly corrosive. These compounds are present, for example, in aerosol sprays, paints, solvents, cleaning products, washing products, detergents, glues, snow clearing salts, etc. Therefore : - Do not suck in air evacuated from premises using such products: hairdressing salons, dry cleaners, industrial premises (solvents), premises containing refrigeration systems (risk of refrigerant leakage), etc. - Do not stock such products close to the boilers. If the boiler and/or peripheral equipment are corroded by such chloride or fluoride compounds, the contractual guarantee cannot be applied. 10 DTG 1300 Eco.NOx/V 23/06/ B

16 Connecting the furnace 1 Hydraulic connections Installation must be carried out in accordance with the prevailing regulations, the codes of practice and the recommendations in these instructions. 1.1 Important recommendations for connecting the boiler to the heating circuit There must be no total or partial closing mechanism between the boiler and the safety valves (France: DTU , NF P ). Heating installations must be designed and implemented to prevent heating circuit water and products contained in it returning to the drinking water system (article 16-7 Departmental Health Regulations). A CB disconnector (area disconnector for different uncontrollable pressures)must be installed for filling the heating circuit according to the NF P standard. Prior connecting the heating circuit hydraulic connections, it is vital that the heating circuits are rinsed to prevent articles that may damage certain parts from being introduced (safety valves, pumps, non return valve...). 1.2 Hydraulic connection of the water circuit for domestic use Please see the document delivered with the domestic hot water preparer. 2 Connecting the gas channel Each time, a blocking tap will be located as near as possible to the heater. Pipe diameters must be defined in accordance with ATG's (Association Technique de Gaz) B171 specifications. The load loss between the meter and heater must be lower than 1 mbar (heater operating). Equipment pressure supply values : - Natural gas H/E (G20) : 20 mbar - Natural gas L/LL (G25) : 25 mbar - Propane (G31) : 37 mbar The boilers leave the factory operating with H/E natural gas. For operating with natural gas L or propane, carry out the actions described in the chapter "Adapting to another gas". In the event where the burner is located at the highest point in the installation, a dry running or water pressure control device my be fitted. Take care to ensure the hydraulic isolation of the primary and secondary circuits using stop valves in order to facilitate maintenance operations on the calorifier. These are used to carry out maintenance on the tank and its systems without draining the entire installation. These valves are also used to isolate the calorifier when conducting a pressurised check on the leak tightness of the installation if the test pressure for the calorifier is greater than the admissible operating pressure. IN ORDER TO FACILITATE BLEEDING, the installation must be filled via the drainage/filling valve 16 DTG 1300 Eco.NOx/V 23/06/ B

17 3 Connecting to a chimneye The equipment must be installed following the codes of practice using sealed stainless steel, aluminium or internally meshed tubing capable of withstanding hot combustion gases and any likely acid condensation. The pipe must be laid out to allow any likely condensation to drain. It must be in accordance with existing regulations for pipes used for this purpose. Standard meshed connection pipes are to be avoided. The pipe connecting the outlet conduit must also be as short as possible and without a reduced diameter. The vertical section of the draught diverter outlet must be a minimum length 3x the diameter of the nozzle before an elbow joint is fitted. The pipe must have a diameter not less than the heater's nozzle diameter along its whole length. This pipe must be able to be easily disassembled and must not have a sudden change in diameter. The outlet conduit must be maintained in a good condition, checked and cleaned at least once a year. Boiler Good Boiler Poor 4 Electrical connections Connections must be made by a qualified technician. Connections inside the command panel must not be modifed in any way. Keep to the polarity shown on the terminals : phase (L), neutral (N) and earth. 23/06/ B DTG 1300 Eco.NOx/V 17

18 . Adapting to another gas Operations to be carried out to allow the change from H/E natural gas to L/LL natural gas or to propane and vice versa.

20 Commissionning 1 Refilling the installation Firstly, fill the tank with domestic hot water. Domestic hot water circuit - Fill the calorifier via the cold water input pipe. If necessary, rinse the domestic circuit (particularly when commissioning), allowing the water to flow for a certain amount of time. - Bleed the domestic circuit (tank and distribution network); to do this: - Completely fill the calorifier with water, leaving the hot water valve open; close this valve only when the flow is regular and there is no noise in the pipes. - Then successively degas all the hot water pipes by opening the corresponding valves in order to prevent the noise caused by air movement when drawing off water. - Check the safety devices (particularly the valve or safety unit), referring to the instructions provided with these components. When reheating domestic hot water, a certain amount of water may escape via the valve or the safety unit because of the expansion of the water in the calorifier. There is no cause for concern at this absolutely normal phenomenon, which must in no event be hindered. Heating circuit Unstick the load pump in necessary: to do this, unscrew the protection cap in front of the pump and insert a screwdriver into the slit (V) on the pump center line. Turn several times to the right and left. - Cold run the pump for a few minutes to enable priming. - The heating circuit must be bled from the highest point of the installation using a suitable bleeding device (not provided). Automatic bleed valve The heating circuit (boiler and tank exchanger) must be filled using the drainage tap to the rear of the tank. When filling the heating circuit, correctly bleed the exchanger on the domestic water calorifier as follows:: Dhw pump V Unscrew the cap on the automatic bleed valve by a few turns Ensure that the non-return angle valve is in the automatic position Ensure that the drainage tap is in the open position Fill the low flow heating circuit using the drainage tap in order to favor the bleed After filling the installation, close the drainage tap Automatic position 2 Final checks before commissioning Check the following points before starting the heater : - Check that the equipment is properly set for the type of gas used. The boilers leave the factory operating with H/E natural gas. - Check the gas pressure upstream from the boiler. - Check the seals on the gas and water connections. 20 DTG 1300 Eco.NOx/V 23/06/ B

21 3 Commissionning The first start-up is to be performed by your installation engineer. - Open the gas blocking tap. - Check that the safety thermostat has not triggered. Remove the safety thermostat hood and press the reset button with a screwdriver. - Place the stop/start switch on On. - Create a requirement for heat. Please consult the document delivered with the command panel before carrying out any action with it. - The safety box carries out its ignition cycle. Switching off : Place the start/stop switch on Off. 4 Furnace operation equipped with safety box 577 DBC Operating principle Operating cycle on safety (start up without flame signal) The ignition and burner surveillance sequences are ensured by the safety box. Normal operating cycle Required input signals Box output signals Contact closed The box closes the TCH contact when there is a requirement for heat. The ignition transformer TA integrated into the safety control box and the ignition burner valve VBA (supply to the ignition burner) are switched on. Gas from the ignition burner is ignited by the ignition electrode and within the time interval ts; a minimum current of 0.3 µa appears on the ionisation sensor SF and the gas valve regulation flap (supplying the principal burner) opens. - If a flame is not detected before the safety time ts, the box makes 2 more ignition attempts. If, at the end of the last attempt, there is still no flame signal, the box goes into safety and the safety indicator comes on. To restart the heater, press the reset button on the safety box. - If there is a loss of flame in normal operation, the box automatically repeats the start up sequence. Resetting : The box is reset after going into safety by pressing the reset button. If the reset button does not work, wait at least 15 seconds before trying a second time. Required input signals Box output signals Contact closed The box may be on safety on its first start up : press the reset button to release it. If the reset button is pressed in normal operation, the gas valves close and the box starts a new ignition sequence. 23/06/ B DTG 1300 Eco.NOx/V 21

23 Checking the anti-smoke release thermostat In the event of smoke release by the anti-blowback device, the antirelease safety device switches off the burner with the safety box on standby for 15 minutes (this is indicated by an alarm indicator flashing). Checking procedure : Turn of the heater and take out the smoke duct linking the heater to the chimney. Close off the smoke duct to the heater using a metal sheet (or other heat proof material). On start up, combustion products are evacuated to the back of the heater by the anti-blowback device opening inside. The anti-blowback thermostat triggers for a few seconds, cuts the burner and starts the safety box timer (alarm indicator flashing). After checking, re-assemble the smoke duct connecting the heater to the chimney. Wait for about 5 minutes (thermostat cooling time) the cut and reconnect the current using the Start/Stop switch. The boiler restarts. 23/06/ B DTG 1300 Eco.NOx/V 23

24 Maintenance 1 Cleaning main burner and ignition burner The main burner and the ignition burner injector with its filter must be regularly cleaned to ensure good performance. Il est conseillé de le faire au moins 1 fois par an. 1 Ionisation probe 2 Ignition electrode 3 Flame diffuser 4 Earth electrode Main burner Switch off the boiler electrical power supply Cut the gas supply. Open the heater door Disconnect the burner connector under the command panel Unscrew the union joint on the gas inlet pipe Unscrew the screws Take out the burner earth wire Disassemble the burner drawer Clean the burner with a brush, a vacuum cleaner or a blower Do not use a metal brush! - Re-assemble the burner earth wire Ignition burner Unscrew the connecting screw, then pull the gas supply pipe towards you Take out the injector and the filter Remove ionisation probe 1 and the earth electrode 4 deposits (for example using sand paper) - Re-attach the supply tube (14 spanner), - Check the position of the ionisation probe 1, the ignition electrode gap 2 and the position of the flame diffuser 3 in terms of the sizes indicated on the drawing (required in the event of heater malfunction).

25 2 Cleaning heater body Sweep the heater. Take out the burner drawer from the heater body. Do not block the gas ramp openings. With the burner out : Take out the column head fixed by 2 screws and toothed washers Take out the insulation Open the sweeping trap by unscrewing the 2 screws Clean the heater body with the special brush delivered with the product. To re-assemble, perform the above actions in reverse order. 3 Maintenance Maintenance and cleaning of the heater must be carried out at least once a year by a qualified technician. Water level Ice Stages We advise you against draining the system unless it is absolutely necessary (For example : Several months' absence with the risk of ice in the building). 4 Periodic checks on the domestic hot water tank Actions Regularly check the level of water in the system and top up if required, taking care that cold water is not added suddenly into the boiler when it is hot. This operation must be carried out several times per season ; if not, look for the probable leak and immediately fix it. In the event that the heating stops during winter, increasing the risk of ice (holiday home for example), it is recommended that sufficient anti-freeze is used to stop the heating water from freezing. As a default, completely empty the installation (check with your installation engineer). It is recommended that you take out a maintenance contract with a qualified installation engineer. In the event that this is not possible, sign a maintenance contract with an after-sales service company recommended by your installation engineer or De Dietrich. Sweeping the smoke conduct and the purge tank must be carried out at least once a year during boiler maintenance. Titane anode No maintenance operations The panel must be switched on to ensure that the anode is working Magnesium anode The titanium anode can be replaced by a magnesium anode. The magnesium anodes must be checked at least every 2, years. After the first check, determine the frequency of future checks on the basis of anode wear. The anodes can be checked by two methods: - Inspection: the anode must be replaced if its diameter is less than 15 mm (original diameter = 33 mm) - Function test: - disconnect the earth wire from the anode 23/06/ B DTG 1300 Eco.NOx/V 25

26 - measure the strength of the current between the tank and the anode ; if the current measured is less than 0.1 ma, the anode should be replaced. Valve or safety unit The safety unit must be periodically manoeuvred (at least once a month). To do this, put the safety unit in the drainage position. This manoeuvre evacuates any desposits which may in time block the safety unit valve. Failure to comply with this maintenance rule may cause damage to the tank structure. Descaling In hard water regions, we recommend descaling the tank annually in order to maintain its performance. - Remove limescale deposits in the form of sludge or strips in the bottom of the tank. On the other hand, do not touch limescale adhering to the walls of the tank as it provides effective protection against corrosion and improves the insulation of the DHW tank. - The exchanger will have to be descaled, if need be, in order to maintain optimum performance. 4.1 Operations to be carried out to check or replace the anode and descale the installation The TAS titanium anode (standard) The magnesium anode (optional) 1. Fit a new watertight seal to the calorifier flange 2. Cut the power supply to the boiler 3. Cut off the cold water supply and drain the DHW tank. To drain though the safety unit, turn the unit to drain and turn on a hot water tap (or a bleed valve) to allow air to enter. 4. Remove the front panel and the sensors. 5. Remove the cover (13 mm spanner). 6. Check the anode and replace it if necessary. 7. When reassembling, replace the watertight seal; to do this: - Replace the lip seal and position it in the visit opening, making sure that you place its lug outside the DHW tank. - Position the retainer ring around the seal, making sure you place the lug above the retainer ring. - Fix the cover to the flange using *1 screws, tightening them uniformly in a cross pattern. 8. Proceed with filling according to the instruction in the chapter "Commissioning". Check the seal and the safety devices on the calorifier after reassembly. The flange mounting bolts must not be excessively tight: 6N.m± : use a torque wrench. Nota: Approximately 6 Nm is obtained by holding the box spanner by the small lever. 26 DTG 1300 Eco.NOx/V 23/06/ B
