vARIABLE CONTROL
OPERATION
The variable control valve can be set to any
heat setting and flame height desired, by sim
-
ply 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 locked positions.
CAUTION: Do not try to ad-
just heating levels by using the
equipment shutoff valve.

Lighting
Instructions
, page 18.
2. Depress control knob and light pilot with
match.
3. Keep control knob pressed in for 30 sec
-
onds after lighting pilot. After 30 seconds,
release control knob. Now follow step 8

Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 24 shows a correct pilot flame pattern.
Figure 25 shows an incorrect pilot flame pat
-
tern. The incorrect pilot flame is not touching
the thermocouple. This will cause the thermo
-
couple to cool. When the thermocouple cools,
the heater will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 25
• turn heater off (see
To Turn Off Gas to Ap-
pliance)
• see
Troubleshooting
, page 22
Note: The pilot flame on natural gas units will
have a slight curve, but flame should be blue
and have no yellow or orange color.
