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 above. If you

don’t smell gas, go to the next step.

5. Press in control knob and turn counterclockwise  

C-clockwise

 to the PILOT position.

Keep control knob pressed in for five (5) seconds (see Figure 29).

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. 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 on page 26.

LIGHTING INSTRUCTIONS

WARNING ICON

G 001

 WARNING

• If fireplace has glass doors, never operate this heater with glass doors

closed. If you operate heater with doors closed, heat buildup inside
fireplace will cause glass to burst. Also if fireplace opening has vents at the
bottom, you must open the vents before operating heater.

• You must operate this heater with a fireplace screen in place. Make sure

fireplace screen is closed before running heater.

1. STOP! Read the safety information above.

2. Make sure manual shutoff valve is fully open.

3. Press in and turn control knob clockwise 

Clockwise

 to the OFF position.

NOTICE

During initial operation of new heater, burning logs will give off a paper-
burning smell. Orange flame will also be present. Open damper or window
to vent smell. This will only last a few hours.

Note:

 Homeowners 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 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.

C. Use only your hand to push in or turn the gas control knob. Never use tools. If the knob

will not push in or turn by hand, don’t try to repair it, call a qualified service
technician or gas supplier. Force or attempted repair may result in a fire or explosion.

D. Do not use this appliance if any part has been under water. Immediately call a

qualified service technician to inspect the appliance and to replace any part of the
control system and any gas control which has been under water.
