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
WARRA TY. Contact the WARRA TOR for conversion infor-
mation. This furnace was equipped at the factory for use on
ATURAL GAS O LY. Conversion to L.P. GAS requires a spe-
cial kit supplied by the WARRA TOR.
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.

General Information
IMPORTANT INFORMATION ABOUT
EFFICIENCY AND INDOOR AIR QUA ITY
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.
