OPERATING
FIREPLACE
Continued
The variable control valve can be set to
any heat setting and flame height de-
sired, by simply turning the control knob
until that setting is attained. Even the
lowest setting provides realistic flames
and glowing embers from two burners.
Selecting higher settings produces greater
heat output. This results in increased
heating comfort.
WARNING: Do not operate
heater between pilot and high
positions.

MANUAL LIGHTING
PROCEDURE
INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 44 shows a correct pilot flame pattern.
Figure 45 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 fireplace will shutdown.
If pilot flame pattern is incorrect, as shown
in Figure 44
• turn fireplace off (see To Turn Off Gas to
Appliance, page 17 [Thermostat-con-
trolled models] or column 1, this page,
[Manually-controlled models])
• see Troubleshooting, pages 21 through 23

FRONT BURNER FLAME
PATTERN
Figure 46 shows correct front burner flame
pattern. Figure 47 shows incorrect front
burner flame pattern. The incorrect burner
flame pattern shows yellow tipping at top of
blue flame.
WARNING: If front burner
flame pattern shows yellow tip-
ping, your fireplace could pro-
duce increased levels of carbon
monoxide. Follow 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 fireplace, causing brief
patches of orange flame.
If front burner flame pattern is incorrect, as
shown in Figure 47
• turn fireplace off (see To Turn Off Gas to
Appliance, page 17 [Thermostat-con-
trolled models] or column 1, this page,
[Manually-controlled models])
• see Troubleshooting, pages 21 through 23
