INSPECTING BURNER
Check pilot flame pattern and burner flame pattern
often.
PILOT FLAME PATTERN
Figure 17 show a correct pilot flame pattern and an
incorrect pilot flame pattern. The incorrect pilot flame
pattern is not touching thermocouple. This will cause
the thermocouple to cool. When the thermocouple
cools, the heater will shut down. If pilot flame pattern is
incorrect, as shown in Figure 17:
•
Turn heater off (see
To Turn OFF Gas to
Appliance
, page 10.

See Troubleshooting, pages 12-13.
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 lint
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, 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 assembly. 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 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.
