Something similar happened to me. A piece of cardboard packing material fell in to the furnace when they were installing it, and it just sat on top of the heat exchanger slowly carbonizing until one day it decided to start smoking. The firefighters spotted the source right away with an IR camera and extinguished it with a shot of CO2, then the furnace guy came and got it out. |
