Condensing Gas Furnaces
Fan Assisted Combustion System
Upflow / Horizontal and Downflow / Horizontal
CAUTION is used to indicate unsafe practices which could
result in minor injury or property damage.
There must be a free flow of fresh air sufficient for efficient
combustion and safe ventilation of your furnace. Do not
allow the louvers on the front panels of your furnace to
become blocked as this will restrict the flow of fresh air.
The combustion air for your furnace must be fresh uncon-
taminated air. Paints, varnishes, laundry bleaches, deter-
gents, many household cleaners, water softening salts,
adhesives, and all such products release fumes containing
compounds which could lead to early heat exchanger and
vent system deterioration. Do not store these type of
products near your furnace and consider fresh air for your
furnace during construction or remodeling.
Never store gasoline, combustible materials, or other
flammable liquids or vapors near your furnace.
If you have a problem, check the "Problem Solver" section
of this manual before you call for a possibly unneeded
service call.
Parts and controls of this furnace are unique. Should
service or modification be required, be sure your servicer
uses only factory authorized parts, kits, or accessories for
this furnace.
CAUTION: Label all wires prior to disconnection
when servicing controls. Wiring errors
can cause improper and dangerous op-
eration.
