Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.That's not a BUrnham model number I need the actual model number on the rating tag on the boiler. It may be inside the burner compartment so you might have to remove the front panel first
I have been called away. I'll respond when I get back
I'm just leaving. I'll need that model number before I can answer any of your questions.
OK, is the vent damper open? is the sight glass more than half full?
Vent damper is on top of the boiler. The exhaust vent is connected to it. If it's open the flat shaft on the motor will be vertical
Do you have electronic ignition or a standing pilot (lit all the time)?
OK, try this, turn the power off at the boiler wait a minute then turn it back on and tell me what happens. Like do you hear the pilot electrode clicking/ticking once the damper opens?
Sounds like maybe a problem with the low water cut off. What brand and model do you have? But the damper did open?
That's the boiler model I need the model of the low water cut off (the device with the water level light)
Is the green light on the LWCO lit?
Ok, there is a safety switch on the side of the draft diverter (the open sheet metal box below the damper. It has 2 wires connected and a small button between the wires. Try pushing the button. If it clicks you have reset it and the boiler will fire up with any luck
What does that mean? you pushed it an nothing happened or you can't find it?
Ok, you need a multi-meter to check voltage to troubleshoot this further. Do you have a meter?
Then there's nothing else you can do to troubleshoot this. You've done all you can without a meter.
