3Technical 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)
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

Important recommendations for connecting the
boiler to the heating circuit
Between the boiler and the safety valves there must be no
complete or partial closing device.
France: DTU - 65.11, § 4.22 - NF P 52-203
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 43-011 standard.
Before connecting the heating circuit hydraulic connections, it is
essential to rinse the heating circuits to remove any particles which
might damage certain components (safety valve, pumps, valves...).
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.
4.4.2Hydraulic connection of the heating circuit
1. Heating flow
2. Heating return
3. Drain cock (connection for 14 mm interior diameter pipe)
Insulate the heating flow and return pipes only outside the
casing.
The drainage device can be connected with a flexible hose.
4.4.3Hydraulic connection of the water circuit for domestic use
See: Domestic hot water calorifier instructions.

7.1.7Checking the downdraught 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).
Check that the anti-overflow system is working correctly on
commissioning for the first time and during annual servicing of the
boiler.
Checking procedure
Only 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 heater
to 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 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.
