INSTRUCTIONS TO THE HOMEOWNER FOR
YOUR SAFETY, READ BEFORE OPERATING

WARNING

IF YOU DO NOT FOLLOW THE
WARNINGS BELOW AND THE
LIGHTING INSTRUCTIONS EXACTLY,
A FIRE OR EXPLOSION CAN RESULT
WITH PROPERTY DAMAGE, PERSONAL
INJURY OR LOSS OF LIFE.
1. Before lighting, smell all around the appliance

area for gas. If the appliance uses LP (bottled)
gas, be sure to smell next to the floor because
LP gas is heavier than air. If you smell gas,
immediately shut off the manual valve in the
gas piping to the appliance or, on LP, at the
tank.
 Do not try to light any appliance. Don’t
touch any electrical switch or use the phone.
Leave the building and call your gas supplier. If
your gas supplier cannot be reached, call the
fire department.

2. Do not force the gas control knob on the appli-

ance. Use only your hand to push down the reset
button or turn the gas control knob.  Never use
any tools. If the knob or reset button will not
operate by hand, replace the control using a
qualified service technician. Force or attempted
repair can result in fire or explosion.

3. The gas control must be replaced if it has been

flooded with water. Call a qualified service
technician.

4. If the red reset button stays depressed after it is

released, replace the gas control.

5. The gas control is a safety device. It must be

replaced in case of any physical damage such as
bent terminals, missing or broken parts, stripped
threads, or evidence of exposure to heat.

IMPORTANT: Follow the operating instructions provided

by the  manufacturer of your heating appliance. The
information below will be of assistance in a typical
control application, but the specific controls used and
the procedures outlined by the manufacturer of your
appliance may differ, and require special instructions.

TO LIGHT THE PILOT BURNER

STOP! Read the safety information in the WARNING.

This appliance has a pilot burner, which must be lit by

hand. If the pilot flame has gone out, follow these instruc-
tions exactly:

1. Set the thermostat to the lowest setting and shut off

electric power to the appliance.

2. Remove the burner access panel if provided on your

appliance.

3. Turn the gas control knob (Figs. 2 or 3) clock-

wise

  to the OFF position.

4. Wait five minutes to allow any gas in the combustion

chamber to vent. If you then smell gas in the appliance area
or near the floor in an LP installation, immediately shut off
the manual valve in the gas piping to the appliance or, with
LP, shut off at the tank.
 Do not touch any electrical switch
or use the phone. Leave the building and call your gas
supplier. If your gas supplier cannot be reached, call the fire
department. Failure to do so may result in fire or explosion.

5. If you do not smell gas, turn knob on gas control

counterclockwise

   to PILOT.

6. Push and hold down red reset button (Figs. 2 or 3) while

you light the pilot burner. Continue to hold down the reset
button for about one minute after the pilot is lit. Release
button; pilot should remain lit. If it goes out, repeat steps 3-
6. If the reset button does not pop up when released, stop
immediately and call your service technician or gas supplier.
If pilot will not remain lit after several tries, turn gas control
knob to OFF and call your service technician or gas supplier.

7. When pilot remains lit, turn gas control knob counter-

clockwise            to ON

8. Replace the burner access panel.
9. Turn on Power.

10. Set thermostat to desired temperature.

TO TURN OFF THE APPLIANCE
VACATION SHUTDOWN: Turn gas control knob clock-

wise             from ON to PILOT. Pilot will remain lit,
ready for return to normal service without relighting.

COMPLETE SHUTDOWN: Turn the gas control knob

clockwise          to OFF. Both pilot and main burner are
shut off. The pilot must be manually relit when normal
burner operation is desired.
