settings" (Page: 25).
1.3.2 Directive 97/23/EC
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.
De Dietrich boilers and DHW tanks conform to the regulations in
article 3.3 of the 97/23/CEE Directive and is backed by the CE mark
for the 90/396/CEE, 92/42/CEE, 2006/95/EC and 2004/108/EC
directives.

the appliance.
If you smell gas, do not use a naked flame, do not smoke,
do not operate electrical contacts or switches (doorbell,
lights, motor, lift, etc.).
1. Isolate the gas supply
2. Open the windows
3. Extinguish all flames
4. Evacuate the premises
5. Contact a qualified professional
6. Inform the gas supplier
Risk of intoxication
Do not obstruct the air inlets in the room (even partially).
If you smell flue gases
1. Switch the appliance off
2. Open the windows
3. Evacuate the premises
4. Contact a qualified professional
2.2 Recommendations
Risk of being burnt
Avoid direct contact with the flame viewport.
Depending on the settings of the appliance:
- The temperature of the flue gas conduits may exceed 60°C
- The temperature of the radiators may reach 95°C
- The temperature of the domestic hot water may reach 65°C
Risk of damage
Do not stock chloride or fluoride compounds close to the
appliance.
Install the appliance in frost-free premises.
Do not neglect to service the appliance: Contact a qualified
professional or take out a maintenance contract for the annual
servicing of the appliance.
Only qualified professionals are authorised to work on the
appliance and the instalation.
Before any work, switch off the mains supply to the
appliance.
Check regularly that the installation contains water and is
pressurised.
Keep the appliance accessible at all times.

DTG 130 Eco.NOx 01/02/11 - 300002915-001-E
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)
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
: Control panel with top of the range regulation

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 anti-
blowback 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).
11. Sensor tube

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.
12
If the reset button is pressed in normal operation, the gas valves
close and the box starts a new ignition sequence.
