Hi I have a British gas 50 F2 whichor I believe to be a potterton profile 50e. Having.firing issues. Fan spinning. New air pressure switch but does not fire up. If I suck on the clear pipe it springs into life. It stays on for about 1 to
2 minutes and flame goes out. Strachan my head at this one now. Any help would be appreciated- posted
