VARIABLE CONTROL
OPERATION
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 realis-
tic, dancing yellow flames. Selecting higher settings produces
greater heat output. This results in increased heating comfort.
WARNING: Do not operate heater between PILOT
and HI positions.
CAUTION: Do not try to adjust heating levels by
using the equipment shutoff valve.

Variable Control Operation
Note:
Home owners generally prefer to operate 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 HI 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 14.
2. Remove control cover log (see Figure 23).
3. Make sure equipment shutoff valve is fully open.
4. Press in and turn control knob clockwise
to the
OFF position.
5. 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, page 14. If you don’t smell
gas, go to the next step.
6. Slightly depress and turn control knob counterclockwise
to the PILOT position. Keep control knob pressed
in for five (5) seconds (see Figure 23).
Note:
You may be running this heater for the first time
after hooking up to gas supply. If so, the control knob may
need to be pressed in for 30 seconds or more. This will al-
low air to bleed from the gas system.

ton. This will light pilot. The pilot is attached to the burner.
If needed, keep pressing ignitor button until pilot lights.
Note:
If pilot does not light, contact a qualified service per-
son or gas supplier for repairs. Until repairs are made, light
pilot with match. To light pilot with match, see Manual
Lighting Procedure, page 16.
8. 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.
