seasonal gas boiler maintenance

Hi there,

I searched back a few years and want to post this again.

I have a GE gas boiler. If it's as old as the house, it's 60 years old. I think the last service tag on the system is from '99. Everything is working fine. Each fall I vacuum out the burners before lighting the pilot and oil the circulator pump. I also have a carbon monoxide detector close by just in case. I don't think my heating bill is especially high either.

That said, if I called a professional for boiler maintenance before the season started, what would he do that I'm not aware of, or can't do myself?

It may vary by dealers. When I was in the field, these are the things I've done on boiler.
  • Remove and clean burners.
  • Brush out the heat exchanger from top to bottom.
  • Remove, inspect, clean, and secure flue pipes.
  • Replace thermocouple.
  • Clean pilot light assembly.
  • Oil pumps (If any), check couplings.
  • Fire off boiler, and check for clean burning flames.
  • Check boiler preassure valve.
  • Check water preassure.
  • Bleed air out of system.
  • Check t-stat and clean if needed.
  • Check baseboard fines to be sure they are clean, clean if needed.
