CLEANING AND MAINTENANCE
WARNING: Turn off heater and let cool before servicing.
CAUTION: You must keep control areas, burner and circulation air passageways of heater clean. Inspect these areas of heater before use. Have the heater inspected yearly by a qualified service person. Heater may need more frequent cleaning due to excess lent from carpeting, bedding material, pet hair, etc.
Make sure grille guard is in place before running heater. If screen or grille guard is removed for servicing it must be replaced prior to operating the heater.
WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.
CLEANING ODS/PILOT AND BURNER
•Use as vacuum cleaner, pressurized air or small soft bristled brush to clean.
CLEANING BURNER PILOT AIR HOLE INLET
We recommend that you clean the unit ever 2,500 hours of operation or every three months. We also recom- mend 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 psig.
This can be done by using a vacuum cleaner in the blow position, 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 burner or pilot assem- bly. In addition, the directions that follow should also be followed.
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 port/slots and holes in the burner.
A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. To clean the pilot assembly find the small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see figure 25). With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if com- pressed air is not available.
