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.   
Installation and repair should be done by a qualified service person. The appliance should be inspected 
before use and at least annually by a professional service person. More frequent cleaning be may require 
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 11). 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.
