CLEANING AND MAINTENANCE

WARNING: Turn off heater and let cool before
servicing.
For maintenance of the inside cabinet or to access the burner
and pilot assembly for cleaning or service. Remove the four
screws(two located on each side) that secure the front shell
to the unit (Figure 6). Gently lift up on the front shell to
disengage the hooks and pull forward to remove it. You will
now be able to access all of the internal components of the
appliance.
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 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 psig.
This can be done by using a vacuum cleaner in the blow
position or using compressed air in a can. If using canned air
please follow the directions on the can. If you don't follow
directions on the can you could damage the burner or pilot
assembly. In addition, the directions below 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 18). 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.
