4. Wait five (5) minutes to clear out any
gas. Then smell for gas, including
near the floor. If you smell gas,
STOP! Follow "B" in the safety in-

in for five (5) seconds (see Figure 22,
page 15).
• 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.
6. With control knob pressed in, press
and release ignitor button. This will
light pilot. The pilot is attached to the
front burner. If needed, keep press-
ing ignitor 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 Light-
ing Procedure, column 3.
7. Keep control knob pressed in for 30
seconds after lighting pilot. After 30
seconds, release control knob.
Note: If pilot goes out, repeat steps
3 through 7, pages 15 and 16.

VARIABLE CONTROL
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 24 shows 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
