WARNING: Do not operate
heater between locked positions.
CAUTION: Do not try to adjust
heating levels by using the equip-
ment shutoff valve.
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 em-
bers from two burners. Selecting higher
settings produces greater heat output. This
results in increased heating comfort.

Figure 26 shows correct front burner flame
pattern. Figure 27 shows incorrect front
burner flame pattern. The incorrect burner
flame pattern shows yellow tipping at top of
blue flame.
If front burner flame pattern is incorrect, as
shown in Figure 27
• turn heater off (see To Turn Off Gas to
Appliance, page 15)

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. 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.
