Instructions to the Homeowner
For Your Safety, Read Before Lighting
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 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.
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.
2. Do not force the gas control knob on the appliance.
Use only your hand to turn the gas control knob.
Never use any tools. If the knob 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. 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 infor-
mation below will be of assistance in a typical con-
trol application, but the specific controls used and
the procedures outlined by the manufacturer of your
appliance may differ, requiring special instructions.
To Turn On Furnace
STOP: Read the safety information above.
1. The lighting sequence on this appliance is automatic;
do not attempt to manually light the main burner.
2. If the furnace does not come on when the thermostat is
set several degrees above room temperature, set the
thermostat to the bottom of its range to reset safety
control.
3. Remove burner access panel if provided on your appli-
ance.
4. Turn the gas control knob (Fig. 5) clockwise to OFF.
5. 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 appli-
ance, or on LP, 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.
6. If you don’t smell gas, turn knob on gas control coun-
terclockwise to ON.
7. Replace burner access panel.
8. Reset thermostat to desired temperature.
9. If burner does not come on when room temperature is
below thermostat setting, turn gas control knob to OFF
and contact a qualified service technician for assis-
tance.
