My house currently has a Weil-McLain boiler, model CGM-6-PI. It has an automatic vent damper that was installed in 1991, but that is sticking in the closed position (I can get it to open by giving it a little jiggle or tap, but it's not a sustainable situation). Think I need to replace the automatic vent damper, but am trying to figure our what models are compatible. If anyone has any suggestions and information, I would appreciate it. Also, can this be a DIY job for someone moderately handy? Though I generally don't mess at all where gas and the boiler are involved, provided I have the right part and wiring harness, this doesn't look like it ought to be overly difficult.
Thanks in advance.
