CLEANING AND
MAINTENANCE
WARNING: Turn off heater and let cool before cleaning.
CAUTION: You must keep control areas, burner, and cir- culating air passageways of heater clean. Inspect these ar- eas of heater before each use. Have heater inspected yearly by a qualified service person. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding mate- rial, pet hair, etc.
WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.
ODS/PILOT AND BURNER
•Use a vacuum cleaner, pressurized air, or small, soft bristled brush to clean.
BURNER PILOT AIR INLET
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.
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 com- pressed air no greater than 30 PSI. Your local com- puter 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 com- pressed 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 as- sembly. There is a small pilot air inlet 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. You may blow through a drinking straw if compressed air is not available.
