FLAME HEATER
BURNER FLAME PATTERN
Figure 27 shows a correct burner flame
pattern. Figure 28 shows an incorrect burner
flame pattern. The incorrect burner flame
pattern shows yellow tipping of the flame. It
also shows the flame higher than one inch
above the log.
Note: When using the heater the first time,
the flame will be yellow for approximately
one hour until the log cures.
NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
or other fine particles enter the
heater and burn causing brief
patches of orange flame.
If burner flame pattern is incorrect, as shown
in Figure 28
• turn heater off (see To Turn Off Gas to
Appliance, page 15)
• see Troubleshooting, pages 17 through 19

WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of carbon
monoxide. If burner flame pat-
tern shows yellow tipping, follow
instructions at bottom of this
page.
INSPECTING
BURNER
Check pilot flame pattern and burner flame
pattern often.
PILOT FLAME PATTERN
Figure 25 shows a correct pilot flame pat-
tern. Figure 26 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 26
• turn heater off (see To Turn Off Gas to
Appliance, page 15)
• see Troubleshooting, pages 17 through 19

OPERATING
HEATER
Continued
The thermostatic control used on this
heater differs from standard thermostats.
Standard thermostats simply turn on and
off the burner. The thermostat used on
this heater senses the room temperature.
The thermostat adjusts the amount of gas
flow to the burner. This increases or de-
creases the burner flame height. At times
the room may exceed the set tempera-
ture. If so, the burner will shut off. The
burner will cycle back on when room
temperature drops below the set tem-
perature. The control knob can be set to
any heat level between HI and LO.
Note : The thermostat sensing bulb mea-
sures the temperature of air near the
heater cabinet. This may not always agree
with room temperature (depending on
housing construction, installation loca-
tion, room size, open air temperatures,
etc.). Frequent use of your heater will let
you determine your own comfort levels.
1. Remove front panel (see Figure 2,
page 4).
2. Follow steps 1 through 5 under Light-
ing Instructions, page 15.
3. With control knob pressed in, strike
match. Hold match to pilot until pi-
lot lights.
4. Keep control knob pressed in for 30
seconds after lighting pilot. After 30
seconds, release control knob.
5. Replace front panel.
6. Turn control knob counterclockwise
C-clockwise
to desired heating level. The
main burner should light. Set control
knob to any heat level between HI
and LO.
