Has anyone seen this before? I couldn’t find another thread for it.
5 year old Lennox sealed combustion furnace with a melted sight-glass at combustion chamber.
Called it out for Specialist Inspection & Service.
I would think that there would be a risk of CO leakage, especially if it completely melted away, not to mention that some overheating situation must have caused it. ???
By the way, I can’t express enough how much help this Board has been since I started “Inspecting” 6 years ago! Thanks, Guys!
