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

Mounted on the gas block to ensure and check ignition sequences, plus burner operation and extinguishing sequences.

2.Gas regulation block:

It has a progressive opening, regulation valve and safety valve in series which is controlled by the boiler adjustment dial.

3.Gas inlet

4.Burner

5.Flame inspection window

6.Ignition electrode:

This ensures ignition burner ignition using a high voltage spark.

7.Ionization probe:

This detects the presence of a burner ignition flame through ionization.

8.Ignition burner

9.Ignition burner gas supply pipe

10.Downdraught thermostat (located on the rear wall of the antiblowback device)

In the event of smoke release, the burner is cut and the boiler goes into standby for 15 minutes. It must not be switched off or moved at any time.The boiler restarts normally after this thermostat has cooled and the 15 minutes has finished (indicated by an alarm indicator flashing on the control panel).

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.

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.
