10. CARE AND MAINTENANCE
WARNING: Turn off heater and let cool before servicing
CAUTION: You must keep control areas, burner, and circulating air passageways of the heater clean.
Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service
technician. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding
material, pet hair, etc.
ODS/PILOT AND BURNER
Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean.
CLEANING BURNER PILOT AIR INLET HOLE
We recommend that you clean the unit every 2,500 hours of operation or every three months. 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 PSl. 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 and pilot for dust and dirt.
3. Blow air through the ports/slots and holes in the burner. Also clean the pilot assembly. 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 Figure13. 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.
