CLEANING AND MAINTENANCE
WARNING:
Disconnect power before attempting any maintenance or cleaning to reduce the risk of fire,
electric shook or personal injury. Turn off heater and let cool before cleaning.
WARNING:
Failure to keep primary air openings of burners clean may result in sooting and property
damage.
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 person. Heater
may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.
CLEANING ODS/IGNITOR AND BURNER
Clean with a vacuum cleaner.
CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE
We recommend that you clean the unit every three months or after 2500 hours of operation. 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 PSI. 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, pilot and primary air inlet holes on injector holder for dust and dirt (see figure 19).
3. Blow air through the ports/slots and holes in the burner.
4. Check the injector holder located at the end of the burner tube again. Remove any large particles of dust,
dirt, lint, or pet hair with a soft cloth or vacuum cleaner nozzle.
5. Blow air into the primary air holes on the injector holder (see Figure19).
6. In case any large clumps of dust have now been pushed into the burner, repeat steps 3 and 4.
Clean the pilot assembly also. 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 20). 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.
