The quest to debug problems with my mates gas fire goes on. We sorted the power flue (the fuse in it was a fast blow and not a time delayed variety as it should have been).
However once that worked (and the fire now lit) we found the fire itself was making a loud ticking sound (nothing to do with the flue), and the maximum flame level was lower than expected.
So we had a tame neighbour (who works for BG) look at it, pulled the whole fire apart and found that somehow water had got into the back of the fire, and in the process somewhat corroded the solenoid on the main gas valve. Alas said BG man was unable to source a replacement.
So does anyone know where to get a Maclaren Products (or Johnson Controls)[1] SM474-0700-VA01 CLA 230V 360mbar gas valve? In fact just a replacement coil may be good enough - the valve body itself may be ok.
[1] tried emailing the makers - no response as yet.
