l VARIABLE CONTROL OPERATION l
The variable control valve can be set to
any heat setting and flame height desired
between high and low by simply turning
the control knob until that setting is at-
tained. Even the lowest setting provides
realistic flames and glowing embers from
two burners. Selecting higher settings pro-
duces greater heat output. This results in
increased heating comfort.

WARNING: Do not operate
heater between pilot and high.
CAUTION: Do not try to adjust
heating levels by using the

INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PA'I-I'ERN
Figure 24 show s a correct pilot flame pattern.
Figure 25 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not touch-
ing the thermocouple. This will cause the
thermocouple to cool. When the thermo-
couple 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
Appliance [Thermostat-Controlled Mod-
els] page 15 or [Variable Manually-Con-
trolled Models] page 16)
see Troubleshooting, pages 18 through 20
