Clean the pilot assembly also. A yellow tip on the pilot flame indicates dust and
dirt in the pilot assembly. There is a small air inlet hole about two inches from
where the pilot flame comes out of the pilot assembly (see Figure 31). With
the unit off, lightly blow air through the air inlet hole. You may blow through a
drinking straw if compressed air is not available.
MAIN BURNER
Periodically inspect all burner flame holes with the heater running. All slotted
burner flame holes should be open with yellow flame present. All round burner
flame holes should be open with a small blue flame present. Some burner
flame holes may become blocked by debris or rust, with no flame present.
If so, turn off heater and let cool. Either remove blockage or replace burner.
Blocked burner flame holes will create soot.
