CARE AND MAINTENANCE

WARNING: Turn off heater and let cool before servicing or cleaning.
CAUTION: You must keep control areas, burner, and circulating air passageways of 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 Figure 24). 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.
