Bought a used forced air/ salamander heater

[diesel lover]

I don't recall ever seeing one of these run properly on #2 FO or diesel. IMO, red dye means 'wrong stuff'. Further comments on this? btw: A simple touch-up I learned to keep odor down and output high is cleaning a little gizmo I can't picture at the moment. IIRC it's a collar or shroud near/around the fuel nozzle and cakes up a bit with dust or whatever, reducing airflow just beyond it and creating a dirtier burn with less O2 going into the swirl. Only needs blown out with compressed air and minimal fuss to reach it, but is a quick fix in a pinch. That said, it's no substitute for a thorough preseason checkup.

Heaters that are designed to burn no 2 fuel oil/ diesel burn it really well! Just as clean as kerosene especially the newer ones.

Mine is designed for no 1 fuel oil but it made me really sick with the red dyed fuel in it. Simply said if it's designed for kerosene only run kerosene !! That's my opinion though.

Once my fuel was changed it burns as clean as a natural gas/ propane heater for the most part !! I just love it perfect price like new
