INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 29 shows a correct pilot flame pattern.
Figure 30 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not touch-
ing the thermocouple. This will cause the
thermocouple to cool. When the thermo-
couple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 30
• turn heater off (see To Turn Off Gas to
Appliance, page 16)
• see Troubleshooting, pages 18 through 20

CLEANING AND
MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burner, and circu-
lating air passageways of heater
clean. Inspect these areas of
heater before each use. Have
heater inspected yearly by a quali-
fied service person. Heater may
need more frequent cleaning due
to excessive lint from carpeting,
pet hair, etc.
ODS/PILOT AND BURNER
• Use a vacuum cleaner or small, soft
bristled brush to clean.
LOGS
• If you remove logs for cleaning, refer to
Installing Logs, pages 13 and 14, to prop-
erly replace logs.
• Replace log(s) if broken or chipped
(dime-sized or larger).
BURNER PRIMARY AIR
HOLE
Air is drawn into the burner through the 8
holes in the brass fitting at the burner en-
trance. There 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 be-
come blocked by debris or rust, with no
flame present. If so, turn off heater and let
cool. Either remove blockage or replace
burner. Blocked burner flame holes will
create soot.
