FOR YOUR SAFETY
READ BEFORE
LIGHTING
WARNING: If you do not fol-
low these instructions exactly, a
fire or explosion may result caus-
ing property damage, personal
injury, or loss of life.
A. This appliance does not have a pilot.
It is equipped with an ignition device
which automatically lights the
burner. Do not try to light the burner
by hand.
®
B. BEFORE OPERATING 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 sup-
plier, call the fire department.
C. Use only your hand to turn the
handle on the equipment shutoff
valve. Never use tools. If the handle
will not turn by hand, don't try to
repair it. Call a qualified service tech-
nician. 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

12
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 in-
formation, column 1. If you don't
smell gas, go to next step.
6.
Turn equipment shutoff valve coun-
terclockwise
(see Figure 18).
7.
This furnace is equipped with an ig-
nition device which automatically
lights the burner. Do not try to light
the burner by hand.
8.
Plug in furnace.
9.
Set thermostat to desired setting. If
thermostat is set above room tem-
perature, the blower will come on.
10. Allow approximately 45 seconds for
ignition to occur. When ignition oc-
curs, the glo-bar will stay on for a
short period of time. The flame sens-
ing probe will sense the burner flame
and shut off glo-bar.
If ignition does not occur within 22
seconds, the ignition control will at-
tempt to light burner three times.
This will take about two minutes. If
ignition does not occur, the ignition
control will lock out the glo-bar and
valve circuit. Air in the gas line or a
short gas interruption will prevent
furnace from igniting. If this hap-
pens, turn thermostat off and wait 5
minutes. Turn the thermostat back
on. The furnace will try to ignite
again.
11. If the furnace still does not ignite, fol-
low instructions To Turn Off Gas to
Furnace, page 13. Call a qualified
service person. Do not attempt to re-
start furnace.
