NOTE:
Before servicing you will need to remove the front panel of the
heater. There are 4 Philips head screws, 2 on the left side and 2 on the
right, securing the front panel to the heater (See Fig. 30). Always allow
the unit to cool for at least thirty minutes before attempting to remove the
front panel.
WARNING:
Turn off heater, unplug electrical cord and let cool
before servicing.
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.
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 a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean burner ports, orifice and
primary burner. Look into 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.
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. 26 & 27 on
page 19). 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.
CLEANING GLASS
Use mild soap and water. Avoid using abrasive cleaners which can scratch the glass. The tempered
glass installed on this product contains a “Low E” coating on the interior surface. If the glass is re
-
moved, you must ensure the “Low E” coated side is installed on the interior side, facing the burner
assembly.
CLEANING CABINET AIR PASSAGEWAYS
Use a vacuum cleaner or pressurized air to clean.
CLEANING FAN (Select Models)
Carefully use a vacuum cleaner or compressed air to keep 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.
CLEANING EXTERIOR
Use a soft cloth dampened with a mild soap and water mixture.
Wipe the cabinet to remove dust.
