Gas supply circuit
1. Connection nut for gas supply
2. Gas valve
3. Electromagnetic valve
4. Thermocouple
5. Burner head
6. Spark plug
7. Overheating protection
8. Gasnozzle
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. Gas valve (2)
3. Electromagnetic valve (3)
4. Gas nozzle (8)
5. Burner head (5), where it is ignited by a
spark in the spark plug (6)
6. thermocouple (4), that is heated by the
heat of the burnt gas
7. overheating protection (7) that controls
the electromagnetic valve in the gas
valve
