Thanks for using JustAnswer!
I need to know if your boiler is gas or oil.
Is there a switch attached to the door? Is it a sealed combustion chamber? Are there openings in the cabinet?
hmmmmmm...no switch attached to the door, I don't think... It's not technically a door. To open the 'door', I lift it up and pull it out. As soon as I lift the door up and pull it out, the ignition kicks in, it goes through the process of restarting, then the pilot lights and it restarts.
Sealed, combustion chamber... or openings in the cabinet... I don't know what those are.
Once you take the 'door' off, everything within the boiler is in sight and accessible.
The boiler is about 5-6 years old.
I can see open flames, yes. They are blue and orange color. The flames look as I would expect, but then again I don't know anything about boilers...
In the sheet metal covering ('door) there are vents... vents on the top and vents at the bottom. Plus the two holes for lifting it up.
Thank you for your help. I appreciate it.
We had the boiler serviced about 3 years ago, so it's probably due for routine servicing again. I'd prefer the professionals do the adjusting of anything that has to do with flames, as I have no idea what I'm doing.
