What it is
This is the Potterton injector, 7.2 mm diameter, listed as INJECTOR - 7.2MM (DUNGS VALVE) under part number 666718. It is a natural gas (NGAS) injector rated for a 60 kW input and is used in the gas train of Potterton Commercial appliances equipped with a Dungs valve assembly. Its function is to meter and direct the gas flow into the burner to produce the correct flame at the pilot or main burner.

- Flame that lifts, flickers excessively or burns yellow rather than a steady blue
- Repeated ignition lockouts or failure to establish flame
- Sooting or discolouration around the injector or burner head
- Visible blockage, debris or damage to the injector orifice
Before you order
