Note:
Home owners generally prefer to op-
erate their heater with the chimney damper
closed. This will put all the heat into the room.
However, there may be times you will desire
the full flames of the High heat setting but will
find the heat output excessive. You can open
the chimney damper (if you have one) fully or
partially to release some of the heat.
WARNING: Damper handle
will be hot if heater has been
running.
1. STOP! Read the safety information on
page 18.
2. Make sure equipment shutoff valve is
fully open.
3. Press in and turn control knob clockwise
to the OFF position.
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 information on page 18. If you don’t
smell gas, go to the next step.
5. Press in control knob and turn counter-
clockwise
to the PILOT position.
Keep control knob pressed in for five (5)
seconds (see Figure 26).
Note:
You may be running this heater for
the first time after hooking up to gas sup-
ply. If so, the control knob may need to be
pressed in for 30 seconds or more. 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 pressing ignitor button until
pilot lights.
Note:
If pilot does not light, contact a
qualified service person or gas supplier for
repairs. Until repairs are made, light pilot
with match. To light pilot with match, see
Manual Lighting Procedure
, page 20.
7. Keep control knob pressed in for 30 seconds
after lighting pilot. After 30 seconds, release
control knob.
• If control knob does not pop out when
released, contact a qualified service person
or gas supplier for repairs.
Note:
If pilot goes out, repeat steps 3
through 7.

VARIABLE CONTROL
OPERATION
The variable control valve can be set to any
heat setting and flame height desired, by sim-
ply turning the control knob until that setting
is attained. Even the lowest setting provides
realistic flames and glowing embers from two
burners. Selecting higher settings produces
greater heat output. This results in increased
heating comfort.
WARNING: Do not operate
heater between locked positions.
CAUTION: Do not try to ad
-
just heating levels by using the
equipment shutoff valve.
