CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE

The primary air inlet opening allow the proper amount of air to mix with the gas. This provides a clean burning ﬂame. Keep these holes clear of dust, dirt, lint, and pet hair. Clean these air inlet opening prior to each heating season. Blocked air opening 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.

We also 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 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.

1.Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.

2.Inspect burner, pilot, and primary air inlet opening on injector holder for dust and dirt (see Figure 26).

3.Blow air through the ports/slots and holes in the burner.

4.Check the injector holder located at the end of the burner tube again. Remove any large particles of dust, dirt, lint, or pet hair with a soft cloth or vacuum cleaner nozzle.

5.Blow air into the primary air opening on the injector holder.

6.In case any large clumps of dust have now been pushed into the burner repeat steps 3 and 4.

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 27). 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.
