Need help on a Peerless gas boiler

Chris_102Chris_102 Posts: 18Member
I have a Peerless gas boiler with a vent damper and a Honeywell Aquastat....the boiler was not firing everyrime and when I went there to troublshoot I found the problem with the vent damper...so I locked the damper open and had no issues until last night...the vent damper was locked open, there was a call for heat and the pilot was lit, but the boiler didn’t fire and the temp in the boiler was 120 degrees. Any thoughts on what the problem could be? Could it be an aquastat problem? I don’t think it’s the gas valve because the pilot was lit. Thanks in advance for the help.

    yes you may have 'multiple problem syndrome', if you're handy with a multi-meter you may be able to figure it out. It may be better to call the pro on this though.

    jump the vent damper till you can replace it, its part of the sequence and needs to have voltage through it

    Run a zip-screw into the pipe, so there is no way the damper can close, also.
