Clean the pilot assembly also. A yellow tip on the
pilot flame indicates dust and dirt in the pilot as-
sembly. There is a small pilot air inlet hole about
2" from where the pilot flame comes out of the
pilot assembly (see Figure 36). 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.
