I have got a very old gas fire - its a Radiation Super Saver. Called British Gas out to service and cos it wasn't igniting properley It needs a new part, but BG cant get it, so i will have to light with a match, as it does still work and is safe!! The part i need is the Spark Ignition Electrode?? The fitter said that if i can find the part he will fit it for me. Any ideas where i could get one please. Thankyou
