HEATER

VARIABLE CONTROL
OPERATION
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 flames and glow-
ing embers from two burners. Selecting
higher settings produces greater heat
output. This results in increased heating
comfort.
WARNING: Do not operate
heater between locked positions.
CAUTION: Do not try to ad-
just heating levels by using the
equipment shutoff valve.

INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 23 shows a correct pilot flame pat-
tern. Figure 24 shows an incorrect pilot
flame pattern. The incorrect pilot flame is
not touching the 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 24
• turn heater off (see To Turn Off Gas to
Appliance, column 1)
• see Troubleshooting, pages 17 through 19

OWNERS MANUAL
FRONT BURNER FLAME
PATTERN
Figure 25 shows correct front burner flame
pattern. Figure 26 shows incorrect front
burner flame pattern. The incorrect burner
flame pattern shows yellow tipping at top of
blue flame.
WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of carbon
monoxide. If front burner flame
pattern shows yellow tipping, fol-
low instructions at bottom of this
page. Yellow flame on rear burner
is normal.
NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
or other fine particles are burned
by heater, causing brief patches
of orange flame.
If front burner flame pattern is incorrect, as
shown in Figure 26
• turn heater off (see To Turn Off Gas to
Appliance, column 1)
• see Troubleshooting, pages 17 through 19
