Does anyone have experience of this particular gas fire
and its faults?

Thermocouple failure is most likely. Bad gas valve a lot less likely.
ISTR paying around £6 for the last thermocouple.

Most probably the thermocouple (not thermostat), a component costing
less than a fiver but replacement cost will be mainly labour.

The pilot light heats up the thermocouple which in turns enables the gas
value to be turned on to provide gas to the pilot when you release the
manual lever/switch.

To the OP - try manually holding the pilot light on for 60 seconds
before releasing the lever/switch. You may be able to just see the tip
of the thermcouple in the pilot flame. It should be glowing red from the
heat of the pilot light.

The pilot flame may not be large enough or has been directed away from
the thermocouple as a result of a small piece of crude partially
blocking the pilot jet.





I'd be surprised if it is a thermocouple rather than one of those
devices where a liquid is vapourised because there is no electrical
supply to the gas fire other than the 1.5V cell used for the igniter;
the few mV from a thermocouple being IMHO too feeble to operate
a mechanical valve.

But thanks for your comment.
