CLEANING AND MAINTENANCE
WARNING: Turn off heater and let cool before cleaning
CAUTION: you must keep control areas, burner, and circulating air passageways of heater clean. Do not close this zone. Inspect these areas of heater before each use. Have heater inspected yearly by a qualified serv- ice person. Heater may need more frequent cleaning due to excessive lint from carpet- ing, bedding material, pet hair, etc.
ODS/PILOT AND BURNER
•Use a vacuum cleaner, pressurized air, or small, soft bristled brush to clean.
CLEANING BURNER PILOT AIR INLET
The primary air inlet holes allow the proper amount of air to mix with the gas. This pro- vides 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 reccommend that you clean the unit every three months dur- ing operation and have heater inspected year- ly by a qualified service person.
We also reccommend than you keep the burn- er tube and pilot assembly clean and free of dust and dirt. To clean these parts we recom- mend using compressed air no greater than 30 PSI. Your local computer store, hardware store, or home center may carry composition. 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 for dust and dirt.
3.Blow air through the ports/slots and holes in the burner.
4.Never insert objects into the pilot tube.
Clean the pilot assembly also. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly (see figure 14). With the
unit off, lightly blow air through the air inlet. You may blow through a drinking straw if compressed air is not available.
