It seems that after sitting for a long while I fired up the furnace to blow out the dust and it seems to work very well. However after using it a few days ago - before this odd 70 degree weather appeared - there is black soot on the outside exhaust of the coach. Time to clean the burners?

I believe I'd look for something impeding the burner airflow. Cobwebs in the air slide, etc. Soot indicates a rich propane/air mixture. Doesn't take much to imbalance it.
