Provide provisions for venting combustion products outdoors
through a proper venting system. Special consideration
should be given to vent/flue pipe routing and combustion air
intake pipe when applicable. Refer to
Vent/Flue Pipe and
Combustion Air Pipe -Termination Locations
for appropriate
termination locations and to determine if the piping system
from furnace to termination can be accomplished within the
guidelines given.
NOTE:
The length of flue and/or
combustion air piping can be a limiting factor in the location
of the furnace.
•
Locate the furnace so condensate flows downwards to the
drain. Do not locate the furnace or its condensate drainage
system in any area subject to below freezing temperatures
without proper freeze protection. Refer to
Condensate Drain
Lines and Trap
for further details.
•
Ensure adequate combustion air is available for the furnace.
Improper or insufficient combustion air can expose building
occupants to gas combustion products that could include
carbon monoxide. Refer to
Combustion and Ventilation Air
Requirements.
•
Set the furnace on a level floor to enable proper condensate
drainage. If the floor becomes wet or damp at times, place
the furnace above the floor on a concrete base sized
approximately 1-1/2" larger than the base of the furnace.
Refer to the
Horizontal Applications and Considerations
for
leveling of horizontal furnaces.
•
Ensure upflow or horizontal furnaces are not installed directly
on carpeting, or any other combustible material. The only
combustible material allowed is wood.
•
A special accessory subbase must be used for upright
counterflow unit installations over any combustible
material (including wood). Refer to subbase instructions
for installation details. (NOTE: A subbase will not be
required if an air conditioning coil is located beneath the
furnace between the supply air opening and the
combustible floor.
•
Exposure to contaminated combustion air will result in
safety and performance-related problems. Do not install
the furnace where the combustion air is exposed to the
following substances:
chlorinated waxes or cleaners
chlorine-based swimming pool chemicals
water softening chemicals
deicing salts or chemicals
carbon tetrachloride
halogen type refrigerants
cleaning solutions (such as perchloroethylene)
printing inks
paint removers
varnishes
hydrochloric acid
cements and glues
antistatic fabric softeners for clothes dryers
and masonry acid washing materials

WARNING
To ensure proper furnace operation, install, operate and maintain the
furnace in accordance with these installation and operation instruc-
tions, all local building codes and ordinances. In their absence, follow
the latest edition of the National Fuel Gas Code (NFPA 54/ANSI Z223.1),
and/or CAN/CSA B149.1-05.1-05 Installation Codes, local plumbing or
waste water codes, and other applicable codes.
A copy of the National Fuel Gas Code (NFPA 54/ANSI Z223.1) can be

The rated heating capacity of the furnace should be greater than or
equal to the total heat loss of the area to be heated. The total heat
loss should be calculated by an approved method or in accor-
dance with “ASHRAE Guide” or “Manual J-Load Calculations” pub-
lished by the Air Conditioning Contractors of America.

WARNING
Follow the instructions listed below when selecting a furnace loca-
tion. Refer also to the guidelines provided in
Combustion and
Ventilation Air Requirements.
•
Centrally locate the furnace with respect to the proposed
or existing air distribution system.
•
Ensure the temperature of the return air entering the
furnace is between 55°F and 100°F when the furnace is
heating.
*NOTE: Please contact your distributor or our website for the applicable Specification Sheet referred to in this manual.
