INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 24 shows a correct pilot flame pat-
tern. Figure 25 shows an incorrect pilot
flame pattern. (
Note: Appearance of pilot
assembly may vary by model.) The incor-
rect pilot flame is not touching the thermo-
couple. This will cause the thermocouple to
cool. When the thermocouple cools, the
heater will shut down.

MANUAL LIGHTING
PROCEDURE
WARNING: Do not operate
heater between PILOT and HIGH
positions.
CAUTION: Do not try to adjust
heating levels by using the
manual shutoff valve.
The variable control valve can be set to
any heat setting and flame height desired,
by simply turning the control knob until
that setting is attained. Even the lowest
setting provides realistic, dancing yellow
flames. Selecting higher settings produces
greater heat output. This results in in-
creased heating comfort.
VARIABLE CONTROL
OPERATION
1. Follow steps 1 through 5 under Light-
ing Instructions, page 14.
2. Depress control knob and light pilot
with match.
3. Keep control knob pressed in for 30
seconds after lighting pilot. After 30
seconds, release control knob. Now
follow step 8, page 14.
CLEANING AND
MAINTENANCE

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,
bedding material, etc.
