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 glowing embers from two burners. Selecting higher
settings produces greater heat output. This results in increased heating comfort.
Do not operate heater between pilot and high.
Do not try to adjust heating levels by using the manual shutoff valve.

Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 23 shows a correct pilot flame pattern. 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.
