CARE AND MAINTENANCE
CLEANING ODS/PILOT AND BURNER
Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean burner ports, orifice and
primary burner. Look into the burner opening and ensure that it is clean.
CLEANING BURNER PILOT AIR INLET HOLE
We recommend that you clean the unit every three months or after 2,500 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.
CLEANING FAN PASSAGEWAYS
Carefully use a vacuum cleaner or compressed air to keep the fan compartment and blades free of
dust and debris.
NOTE:
The fan motor is pre-lubricated for extended bearing life and requires no further lubrication.
WARNING
: Turn off heater and let cool before servicing.
CAUTION
: You must keep the control areas, burner, and circulating air passageways of the
heater clean. Inspect these areas of the heater before each use. Have the 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.
WARNING
: Failure to keep the primary air opening(s) of the burner(s) clean may result in
sooting and property damage.
CAUTION
: Never use a wire, needle, or similar object to clean ODS/pilot. This can damage
ODS/ pilot unit.
1.
Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.
2.
Remove 4 screws - 2 screws on each side of the front panel.
3.
Pull front panel forward.
4.
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 Fig. 21 & 22 on page 21).
With the unit off, lightly blow air through the
air inlet hole. You may blow through a drinking straw if air is not available.
5.
Replace front panel when completed, using the screws removed.
