2 - DO NOT obstruct air flow to unit. Unit must receive an
unobstructed flow of combustion and ventilating air.
3 - DO NOT store chlorine or fluorine products near unit or
introduce these products into the combustion air.
These products can cause furnace corrosion.
4-
DO NOT draw return air from a room where this
furnace, or any other gas appliance (ie., a water
heater), is installed.
When return air is drawn from a
room, a negative pressure is created in the room. If a
gas appliance is operating in a room with negative
pressure, the flue products can be pulled back down
the vent pipe and into the room. This reverse flow of
the flue gas may result in incomplete combustion and
the formation of carbon monoxide gas. This toxic gas
might then be distributed throughout the house by
the furnace duct system.
Your furnace is a gas appliance.
It is critical that the gas
supplied to the unit be completely burned to avoid the proĆ
duction of carbon monoxide gas. Complete combustion
of the gas requires, but is not limited to, correct gas presĆ
sure and gas flow rate, adequate combustion air, and
proper venting.
WARNING
Carbon monoxide gas is invisible, odorless, and
toxic.
Exposure to this gas can cause personal injury and even
death to all occupants, including pets. Any item that is
powered by or gives off heat from a combustion process
(including lawn mowers, automobiles, and fireplaces) has
the potential to produce carbon monoxide gas. Because
of this,
the use of a carbon monoxide detector in your
home is recommended, even if you do not own gas
appliances.
Reliable detectors are available at reasonĆ
able retail prices. Contact your dealer for more details
about this investment in your safety.
Your furnace is designed to meet standards set by nationĆ
al agencies, and to operate safely when properly installed
and maintained. However, the unit's performance can be
greatly impacted by the individual installation and the opĆ
erating environment. It is your responsibility to ensure
that this appliance is maintained. Proper maintenance is
critical for your safety and the satisfactory operation of the
product.
Annual inspection and maintenance of this
appliance is strongly recommended.
Contact your
dealer for an inspection by a qualified service technician.

Lighting Information and Operation
WARNING
If you do not follow these instructions exactly, a fire
or explosion may result causing property damage,
personal injury or loss of life.
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.
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, do not try to repair it, call a qualified service
technician. Force or attempted repair may result in a fire
or explosion.
Placing furnace into operation:
F8AUH units are equipped with an electronic ignition
system. Do not attempt to manually light burners on
these furnaces. Each time thermostat calls for heat, the
burner will automatically light.
