INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 21 shows a correct pilot flame pat-
tern. Figure 22 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.
If pilot flame pattern is incorrect, as shown
in Figure 22
• turn heater off (see To Turn Off Gas to
Appliance, column 1)
• see Troubleshooting, pages 17 through 19

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 15.
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 15.
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 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.
