3 Technical description

3.1 General description

Boilers in the DTG 130 Eco.NOx range have the following
characteristics:

- Cast iron floor-standing gas boiler.

- Connecting to a chimney.

- Atmospheric burner with total premixing and very low pollutant
emission.

- Heating body in cast iron with overlapping studs making it possible
to obtain extremely high efficiency. Also, the baffling in the smoke
circuits limits the natural chimney effect and gives high
performance yields.

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

- Flue gas anti-overflow safety system. The downdraught thermostat
located in the draught diverter cuts off the gas supply and puts the
boiler 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 of
sections which make up the boiler.
For example: DTG 130-5 Eco.NOx: 5 section boilers

3.4 Operating principle

577 DBC safety box



Operating principle

The ignition and burner surveillance sequences are ensured by the
safety 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 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 ionization sensor SF and the gas valve regulation flap (supplying
the 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 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.



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



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

 Operating cycle with the downdraught thermostat

cut off

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). The 15 minute timed period can only be interrupted by a
sector cut.

To restart the boiler:

Wait for around 5 minutes (thermostat cooling time) and press the
reset button on the safety control box. If interruptions of this kind
happen repeatedly, contact your fitter.
