5. Any additions, changes or conversions required in order for the
furnace to satisfactorily meet the application needs should be
made by a qualified installer, service agency or the gas sup-
plier, using factory specified or approved parts. Read your
WARRANTY. Contact the WARRANTOR for conversion infor-
mation. This furnace was equipped at the factory for use on
NATURAL GAS ONLY. Conversion to L.P. GAS requires a spe-
cial kit supplied by the WARRANTOR.
6. A furnace needs an adequate supply of combustion and venti-
lation air for proper and safe operation. Do not block or ob-
struct air openings on the furnace or air openings supplying the
area where the furnace is installed. Do not store anything
around the furnace that could block the flow of fresh air to the
unit. Your installation may receive air from the inside heated
space, from the outside, from the attic or crawl space. When-
ever adding insulation, be sure the air supply openings are not
covered.

8. Should the gas supply fail to shut off or if overheating occurs,
shut off the gas valve to the furnace before shutting off the
electrical supply.

IMPORTANT INFORMATION ABOUT
EFFICIENCY AND INDOOR AIR QUALITY
Central cooling and heating equipment is only as efficient as the
duct system that carries the cooled or heated air. To maintain effi-
ciency, comfort and good indoor air quality, it is important to have
the proper balance between the air being supplied to each room
and the air returning to the cooling and heating equipment.
Proper balance and sealing of the duct system improves the effi-
ciency of the heating and air conditioning system and improves
the indoor air quality of the home by reducing the amount of air-
borne pollutants that enter homes from spaces where the duct-
work and / or equipment is located. The manufacturer and the
U.S. Environmental Protection Agency’s Energy Star Program
recommend that central duct systems be checked by a qualified
contractor for proper balance and sealing.

WARNING
DUCT LEAKS CAN CREATE AN UNBALANCED SYSTEM
AND DRAW POLLUTANTS SUCH AS DIRT, DUST, FUMES
AND ODORS INTO THE HOME CAUSING PROPERTY DAM-
AGE. FUMES AND ODORS FROM TOXIC, VOLATILE OR
FLAMMABLE CHEMICALS, AS WELL AS AUTOMOBILE
EXHAUST AND CARBON MONOXIDE (CO), CAN BE
DRAWN INTO THE LIVING SPACE THROUGH LEAKING
DUCTS AND UNBALANCED DUCT SYSTEMS CAUSING
PERSONAL INJURY OR DEATH (SEE FIGURE 1).
• IF AIR-MOVING EQUIPMENT OR DUCTWORK IS LO-
CATED IN GARAGES OR OFF-GARAGE STORAGE
AREAS - ALL JOINTS, SEAMS, AND OPENINGS IN THE
EQUIPMENT AND DUCT MUST BE SEALED TO LIMIT
THE MIGRATION OF TOXIC FUMES AND ODORS IN-
CLUDING CARBON MONOXIDE FROM MIGRATING INTO
THE LIVING SPACE.
• IF AIR-MOVING EQUIPMENT OR DUCTWORK IS LO-
CATED IN SPACES CONTAINING FUEL BURNING APPLI-
ANCES SUCH AS WATER HEATERS OR BOILERS - ALL
JOINTS, SEAMS, AND OPENINGS IN THE EQUIPMENT
AND DUCT MUST ALSO BE SEALED TO PREVENT DE-
PRESSURIZATION OF THE SPACE AND POSSIBLE MI-
GRATION OF COMBUSTION BYPRODUCTS INCLUDING
CARBON MONOXIDE INTO THE LIVING SPACE.
