Hi guys,

Went to have a look at a Baxi Bermuda 50/5 inset fire today. customer saying it wont light,

when i got there he had no MI,

what was happening was when i pressed the ignition button the solenoid opened and let gas through to the pilot (the solenoid made a right noise but apparently its always done it) the spark electrode began its sequence of about 20 sparks but no ignition,

i put a naked flame to the pilot (thinking the spark wasnt strong enough) but the gas was coming from the pilot with some speed and just blowing the flame out, the pilot didnt even come close to lighting,

there was definatley gas coming from the pilot and the customer was sure that no gas work had been done at the property so that ruled out un purged gas pipe.

my thoughts are its either a faulty gas valve/solenoid (opening to much and letting to much gas flow to the pilot) or the pilot is faulty/unrestricted.

i am not familiar with these fires but i couldnt see anywhere for the pilots gas flow to be altered which swayed me towards the gas valve,

i ended up having to walk away because i wasnt 100% sure

do any of you fellas know what it could have been or have you come accross this before?

thanks all

James

Could be to do with the pilot & sensing tube, if not clear & set up right will make pilot lift off [ oxy-pilot].

did you check presser from meter might be over gas ,or i am with you gas valve!!!

agree with aggis,first check gas pressures at inlet,then check the oxysafe hole in the pilot assembly for blockages,the ignition leads can sometimes touch the body and arc out dont worry about the solenoid they are noisy on purpose they are a designed to make a noise so you know its trying to light i would not be looking at a gas valve more a ignition/oxysafe assembly issue

faulty lead, check the black one for volts.
