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

I had exactly these symptoms on mine, coming home late one night.
Had it in bits, but couldn't get it working, gave up and went to bed.
In the morning, went outside and found a bird had jammed itself in
the flue terminal. Pulled out bird, and it all sprung back into life.

Look for anything blocking the flue or any of the fanned air pathways.
Check through the viewing window that flames are entirely blue, with
no white luminous showing.
