OPERATING HEATER
FOR YOUR SAFETY READ
BEFORE LIGHTING
WARNING: If you do not follow these instructions
exactly, a fire or explosion may result causing prop-
erty damage, personal injury or loss of life.
A. This appliance has a pilot which must be lighted by hand.
When lighting the pilot, follow these instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area
for gas. Be sure to smell next to the floor because some gas
is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any phone
in your building.
• Immediately call your gas supplier from a neighbor’s
phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire de-
partment.
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 techni-
cian 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.
1. STOP! Read the safety information, column 1.
2. Make sure equipment shutoff valve is fully open.
3. Set switch in OFF position.
LIGHTING INSTRUCTIONS
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.
NOTICE: During initial operation of new heater, burning
logs will give off a paper-burning smell. 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 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.
WARNING: Burner will come on automatically
within one minute when the selector switch is in the
ON position after the pilot is lit.
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! Fol-
low “B” in the safety information, column 1. If you don’t
smell gas, go to the next step.
6. Press in and turn control knob counterclockwise
to the PILOT position. Press in control knob for five (5)
seconds (see Figure 22).
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.
7. 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 stay lit, 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 15.
