CLEANING BURNER PILOT AIR INLET HOLE
The primary air inlet holes allow the proper amount of air to mix with
the gas. This provides a clean burning flame. Keep these holes clear
of dust, dirt, and lint. Clean these air inlet holes prior to each heating
season. Blocked air holes will create soot. We recommend that you
clean the unit every three months during operation and have heater
inspected yearly by a qualified service person.

clean the unit every three months during operation and have heater

We also recommend that you keep the burner tube and pilot
assembly clean and free of dust, dirt, lint and pet hair. To clean these
parts we recommend using compressed air no greater than 30 PSI.
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.

2.
Inspect burner, pilot for dust and dirt.
3.
Blow air through the ports/slots and holes in the burner.
Clean the pilot assembly also. A yellow tip on the pilot flame
indicates 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 30). 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.
