pushed into the burner repeat steps 3 and 4,

Clean the pilot assembly also. A yellow tip on the

sembly. There is a small pilot air inlet hole about
two inches from where the pilot flame comes out
of the pilot assembly (see Figure 39). With the
unit off, lightly blow air through the air inlet hole.
You may blow through a drinking straw if com-
pressed air is not available.
