3 Technical description

3.1 General description

Boilers in the DTG 130 Eco.NOx range have the followingcharacteristics:- Cast iron floor-standing gas boiler.

- Connecting to a chimney.

- Atmospheric burner with total premixing and very low pollutantemission.

- Heating body in cast iron with overlapping studs making it possibleto obtain extremely high efficiency. Also, the baffling in the smokecircuits limits the natural chimney effect and gives highperformance yields.

- Efficient insulation of the entire boiler unit for very low losses to theambient air.

- Flue gas anti-overflow safety system. The downdraught thermostatlocated in the draught diverter cuts off the gas supply and puts theboiler into safety shutdown in the event of flue gas blow back.

- Electronic control panel:- B: Basic control panel- Diematic 3 (D): Control panel with top of the range regulation

The control panel gives priority to producing domestic hot water.The figure given after DTG 130 indicates the number ofsections which make up the boiler.For example: DTG 130-5 Eco.NOx: 5 section boilers

3.4 Operating principle

577 DBC safety box

Operating principleThe ignition and burner surveillance sequences are ensured by thesafety box.

Normal operating cycle

If heating is required, the boiler thermostat TCH closes the contact.The ignition transformer TA integrated into the safety control box andthe ignition burner valve VBA (supply to the ignition burner) areswitched on.Gas from the ignition burner is ignited by the ignition electrode andwithin the time interval ts; a minimum current of 0.3 µA appears onthe ionization sensor SF and the gas valve regulation flap (supplyingthe principal burner) opens.

Operating cycle on safety (start up without flame signal)

If a flame is not detected before the safety time ts, the box makes 2more ignition attempts. If, at the end of the last attempt, there is stillno flame signal, the box goes into safety and the safety indicatorcomes on. To restart the heater, press the reset button on the safetybox.If there is a loss of flame in normal operation, the box automaticallyrepeats the start up sequence.

ResettingThe box is reset after going into safety by pressing the reset button.If the reset button does not work, wait at least 15 seconds beforetrying a second time.

The box may be on safety on its first start up. Press the resettingbutton of the burner.

If the reset button is pressed in normal operation, the gas valvesclose and the box starts a new ignition sequence.

7.1.4 Checking pressure to the nozzle

- Unscrew the screw inside the nozzle pressure socket a few turns.- Connect a manometer to the pressure outlet. Check that the

pressure is correct.

- Tighten the pressure socket screw.

Carry out a gas tightness check.

7.1.5 Checking burner safety

Close the gas valve. Check the reaction of the safety system. (Safety box on safetybecause of ionization fault).

7.1.6 Checking the safety thermostat

Place the Summer/Winter switch on to cut the heatingaccelerator to prevent the temperature rising in the installation.Place the 3 position switch " - AUTO - TEST STB" on the TESTSTB position. The burner starts regardless of the setting. Keep theswitch in this position until the safety thermostat cuts (110ºC).

To restart the heater, press the safety thermostat reset button andrepeat the starting operations.

7.1.7 Checking the downdraught thermostat

In the event of smoke release by the anti-blowback device, the anti-release safety device switches off the burner with the safety box onstandby for 15 minutes (this is indicated by an alarm indicatorflashing).Check that the anti-overflow system is working correctly oncommissioning for the first time and during annual servicing of theboiler.

Checking procedureOnly a qualified professional may carry out the check.

Ensure correct ventilation in the premises during the check.

- Turn of the heater and take out the smoke duct linking the heaterto the chimney. Block the boiler flue gas nozzle using a metal plate(or other heat-resistant material).

- On start up, combustion products are evacuated to the back of theheater by the anti-blowback device opening inside.

- The anti-blowback thermostat triggers for a few seconds, cuts theburner and starts the safety box timer (alarm indicator flashing).

- After checking, re-assemble the smoke duct connecting the heaterto the chimney. Wait for about 5 minutes (thermostat cooling time)the cut and reconnect the current using the Start/Stop switch. Theboiler restarts.
