five (5) seconds (see Figure 23, page 16).
If control knob does not pop out when
released, contact a qualified service
person or gas supplier for repairs.
Note:
You may be running this
heater for the first time after hook-
ing up to gas supply. If so, the con-
trol knob may need to be pressed in
for 30 seconds. This will allow air to
bleed from the gas system.

release ignitor button. This will light
pilot. The pilot is attached to the front
burner. If needed, keep pressing igni-
tor button until pilot lights.
Note:
If pilot does not light, contact
a qualified service person or gas sup-
plier for repairs. Until repairs are
made, light pilot with match. To light
pilot with match, see Manual

VARIABLE CONTROL
OPERATION
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.

INSPECTING
BURNERS
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 25 shows a correct pilot flame pattern.
Figure 26 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 26
turn heater off (see To Turn Off Gas to
Appliance, page 16 [Thermostat-Con-
trolled Models] or page 17 or [Variable
Manually-Controlled Models])
see Troubleshooting, pages 19 through 21
