To ensure proper furnace operation, install, operate, maintain
and service the furnace in accordance with the installation,
operation and service instructions, 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/CGA B149 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)

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 accordance with “ASHRAE Guide” or “Manual
J-Load Calculations” published by the Air Conditioning
Contractors of America.

Follow the instructions listed below when selecting a
furnace location. Refer also to the guidelines provided in the
Combustion and Ventilation Air Requirements section in this
manual or the installation instructions for details.
• 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.
• If the furnace is installed in an application where the
typical operating sound level of a furnace is deemed
objectionable, an optional sound reduction kit is
available. Consult your local distributor for more details.
• Provide provisions for venting combustion products
outdoors through a proper venting system. Special
and combustion air intake pipe when applicable.
• Refer to the Vent/Flue Pipe and
Combustion Air Pipe -Termination Locations section in
this manual or the installation instructions for appropriate
termination locations. Also for 90% furnaces, refer to the
Vent/Flue Pipe and Combustion Air Pipe -Termination
Locations section in this manual or the installation
instructions to determine if the piping system from
furnace to termination can be accomplished within the
guidelines given
•
can be a limiting factor in the location of the furnace.
• Locate the 90% furnace so that the condensate can be
piped at a downward slope away from the furnace 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 the Condensate Drain Lines and Trap section in this
manual or the installation instructions for further details.
•
condensate drainage. If the floor becomes wet or
concrete base sized approximately 1-1/2” larger
than the base of the furnace. Refer to the Horizontal
Applications and Considerations section in this manual
or the installation instructions for leveling of horizontal
furnaces.
•
directly on carpeting, or any other combustible material.
The only combustible material allowed is wood.
• 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
