MAINTENANCE
WARNING: Turn off heater and let cool before cleaning.
CAUTION: You must keep control areas, burners, and circulating air passageways of heater clean. In- spect these areas of heater before each use. Have heater inspected yearly by a qualified service person. Heater may need more frequent cleaning due to exces- sive lint from carpeting, pet hair, bedding material, etc.

CLEANING BURNER INJECTOR HOLDERS AND PILOT AIR INLET HOLES
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, lint, and pet hair. 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.
We also recommend that you keep the burner tubes 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 com- pressed air in a can. You can use a vacuum cleaner in the blow position. If using compressed air in a can, please follow the direc- tions 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 burners, pilot, and primary air inlet holes on injector holder for dust and dirt (see Figures 41 or 42).
3.Blow air through the ports/slots and holes in the burners.
4.Check the injector holders located at the end of the burner tubes 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 holes on the injector holders.
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 43). With the unit off, lightly blow air through the air inlet hole. The access hole for propane/LP pilot is on the front of the burner carriange as shown in Figure 43. The access hole for natural pilot is behind the pilot bracket on the top of burner carriage (see Figure 43). You may blow through a drinking straw if compressed air is not available.
