recommend that you keep the burner
tube and pilot assembly clean and free
of dust and dirt. To clean these parts
we recommend using compressed
air no greater than 30 PSl.Your local
computer store, hardware store, or
home center may carry compressed
air in a can. You can use a vacuum
cleaner in the blow position. If using
compressed air in a can, please follow
the directions on the can. If you don't
follow directions on the can, you could
damage the pilot assembly.

Also clean the pilot assembly. A
yellow tip on the pilot flame
cates dust and dirt in the pilot
assembly. There is a small pilot air
inlet hole about two inches from
where the pilot flame comes out of
the pilot assembly (see Figure 25).
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.
