LIGHTING
INSTRUCTIONS
WARNING:
• If fireplace has glass doors,
never operate this heater with
glass doors closed. If you op-
erate heater with doors closed,
heat buildup inside fireplace
will cause glass to burst. Make
sure there are no obstructions
across opening of fireplace.
• You must operate this heater
with a fireplace screen in place.
Make sure fireplace screen is
closed before running heater.
NOTICE: During initial operation
of new heater, burning logs will
give off a paper-burning smell.
Orange flame will also be pres-
ent. Open damper or window to
vent smell. This will only last a
few hours.
Note: Home owners generally prefer to operate
their heater with the chimney damper closed.
This will put all the heat into the room. How-
ever, 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 chim-
ney 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 16.
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 16. If you donʼt
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 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.
7. With control knob pressed in, press and
release ignitor button. This will light pilot.
The pilot is attached to the burner. If needed,
keep pressing ignitor button until pilot

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 18.
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.
9. Slightly depress and turn control knob
counterclockwise to the HI position.
