the ventilator is working properly and no flammable materials are still next to/in/on the
heater. Also perform a gas leakage test.
Repairs must only be performed by qualified people. Never open the heater yourself!
Make sure that only original parts are used; that definitely applies to the gas hose and
the pressure regulator!
The heater must be inspected at least once a year by a qualified person.
Gas supply circuit
1. Connection nut for gas supply
2. Electromagnetic valve
3. Gas nozzle
4. Thermocouple
5. Burner head
6. Spark plug
7. Overheating protection
Operating principle:
When the heater is connected to the
gas supply, the gas passes in
sequence through the following parts:
1. Gas supply opening (1)
2. Electromagnetic valve (2)
3. Gas nozzle (3)
4. burner head (5), where it is ignited by a spark in the spark plug (6)
5. thermocouple (4), that is heated by the heat of the burnt gas
6. overheating protection (7) that controls the electromagnetic valve in the gas valve
