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

OK, is the vent damper open? is the sight glass more than half full?

Customer: replied 1 year ago.
Don't know where the vent damper is located and the sight is at halfway
Expert:  Rick replied 1 year ago.

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

Customer: replied 1 year ago.
Vent is open yes

Do you have electronic ignition or a standing pilot (lit all the time)?

Customer: replied 1 year ago.
Electronic
Expert:  Rick replied 1 year ago.

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?

Customer: replied 1 year ago.

Expert:  Rick replied 1 year ago.

Sounds like maybe a problem with the low water cut off. What brand and model do you have? But the damper did open?

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

Customer: replied 1 year ago.
I got nothing
Expert:  Rick replied 1 year ago.

What does that mean? you pushed it an nothing happened or you can't find it?

Customer: replied 1 year ago.
I pushed the button and I didn't get anything
Expert:  Rick replied 1 year ago.

Ok, you need a multi-meter to check voltage to troubleshoot this further. Do you have a meter?

Customer: replied 1 year ago.
No I don't have meter.
Expert:  Rick replied 1 year ago.

Then there's nothing else you can do to troubleshoot this. You've done all you can without a meter.

Thank you Rick
