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, dancing yellow flames. Selecting higher settings produces greater heat output. This results in in- creased heating comfort.

WARNING: Do not operate heater between PILOT and HIGH positions.

CAUTION: Do not try to adjust heating levels by using the manual shutoff valve.

INSPECTING

BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 24 shows a correct pilot flame pat- tern. Figure 25 shows an incorrect pilot flame pattern. (Note: Appearance of pilot assembly may vary by model.) The incor- rect pilot flame is not touching the thermo- couple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.
