I have a newyorker rg170 3 closed loop standing pilot boiler in my basement.didnt use it for the first year , tried to fire it up last season and had to replace a gas valve,thermalcouple,and pilot it worked for all of two hours and the pilot went out. called service guy again he adjusted flame, installed a shield, still the same thing. the company said that they don't have any info says its to old, any help would be greatly appreciated. was wondering if it could be the main burner itself,thats about the only thing that didn't get replaced
So a shield was left out of place ? Or it got blown off ?
If the pilot is not positioned properly then the burner can fill the chamber with gas , then when it does ignite the explosion can blow the flame out. The pilot flame also has to be heating the thermocouple when the Fan is running or not. If the fan affects the pilot then the fan may be creating a draft.
If you have Exchanger problems, you can look at the flame when the fan is running, to make sure the fan is not pushing air into the burn chamber. If it does then the heat exchanger has holes in it, and can be hazardous to your health.
The color of the flame should tell you if your Burner is burning properly.
Be careful playing with Gas.
