MAINTENANCE
Continued
6.In case any large clumps of dust have now been pushed into the burner repeat steps 3 and 4, page 21.
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 38). 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.
