my boiler was not working ,its was the fan but now the fan is working .its lighting up and there is sparkle,just there no gas commin through .i m wandering if there switch for the gas to come through .any help would be appreciated .i dont have hot water since 2 months.
if the electordes are sparking, the problem lies with the gas valve (or valve solenoids) you should not interfer with these yourself unless qualified and with the correct tools to set and test them........
