When fault finding on these appliances you may need to check the resistance of the gas valve solenoids, two types of gas valves maybe fitted to these appliances resistance readings below.

Sit gas valve resistance of 400 ohms for the top solenoid and 180 ohms bottom solenoid.

Other gas valve 140-180 ohms for the top and bottom solenoid.

Both gas valves work on 34v DC
