Customer Question

I have a peerless pinnacle boiler that has ignition, but will not fire. The homeowner tells me it has been lighting very hard lately. I removed the ignitor, cleaned it and set the gap at 1/4 inch and it made no difference. I checked and do have fuel. Do you have any suggestions?                &n bsp;                                                                    Thanks, Craig

Hi,

 

I would check the flue and the burner first.

 

Thanks

Mark,
I have checked the flue and burner.Both check out fine. Could it be a fuel/air mix problem?

Hi,

 

Yes it can be, are you pulling the combustion air from outside ?

Hi,

 

If all above items are good and your air is coming from outdoors then the only real cause left is the gas control valve.

 

Thanks

Turns out the problem was a melted plastic spreader plate located after the gas valve.I had to reprogram the boiler to have a longer postpurge so it will not melt the new spreader.
