Soot

2018 Thor Palazzo 33.2, Have soot on outside of coach by furnace vent. What might be wrong?

Running too rich. Air intake needs to be adjusted. Check your furnace manual.

Could also be the propane regulator providing too much pressure.

Thank you very much.

Mud daubers? I had a whole lot of soot in mine and eventually the heat exchanger cracked and filled my coach with fumes. I had to replace my furnace.



I installed a screen over the exhaust of my new unit to keep these insects out.
