INSPECTING BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 36 shows a correct pilot flame pattern. Figure 37 shows an
incorrect pilot flame pattern. The incorrect pilot flame is not
properly heating the thermocouple. When the thermocouple cools,
the heater will shut down.

If pilot flame pattern is incorrect, as shown in Figure 37

• turn heater off (see To Turn Off Gas to Appliance, page 17)

• see Troubleshooting, pages 21 through 23

BURNER FLAME PATTERN

Figure 38 shows a correct burner flame pattern. Figure 39 shows an
incorrect burner flame pattern. If burner flame pattern is incorrect,

• turn heater off (see To Turn Off Gas to Appliance, page 17)

• see Troubleshooting, pages 21 through 23

BURNER PRIMARY AIR HOLES

Air is drawn into the burner through the holes in the fitting at the
burner entrance. These holes may become blocked with dust or lint.
Periodically inspect these holes for any blockage and clean if
needed. Blocked air holes will create soot.

MAIN BURNER

Periodically inspect all burner flame holes with the heater running. All
slotted burner flame holes should be open with yellow flame present.
All round burner flame holes should be open with a small blue flame
present. Some burner flame holes may become blocked by debris or
rust, with no flame present. If so, turn off heater and let cool. Remove
blockage. Blocked burner flame holes will create soot.

CLEANING AND
MAINTENANCE

 WARNING: Turn off heater and let cool before

cleaning.

 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.

CLEANING BURNER INJECTOR HOLDER
AND PILOT AIR INLET HOLE

The primary air inlet holes allow the proper amount of air to mix with
the gas. This provides a clean burning flame. Keep these holes clear
of dust, dirt, lint, and pet hair. Clean these air inlet holes prior to each
heating season. Blocked air holes will create soot. We recommend
that you clean the unit every three months during operation and have
heater inspected yearly by a qualified service person.

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. Your local
computer store, hardware store, or home center may carry com-
pressed air in a can. 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.
