I have a Empire wall furnace (faw40-1-ssp) that keeps blowing the pilot out when the main burners ignite..It seems to build up a small amount of gas before ignition.
I've had a couple different service calls on it, and even contacted Empire,
( not much help ) Not sure what else to check..
Any other ideas?
It's been cleaned, gas co, has check gas pressure, and pilot adjusted..
