•
The furnace heat exchanger, components, duct
system, air filters and evaporator coils are thoroughly
cleaned following final construction clean up by a
qualified person.
•
All furnace operating conditions (including ignition,
input rate, temperature rise and venting) are verified
by a qualified person according to these installation
instructions.
•
Furnace doors must be in place on the furnace while
the furnace is operating in any mode.
•
Damage or repairs due to failure to comply with these
requirements are not covered under the warranty.
NOTE: The Commonwealth of Massachusetts
requires that the following additional
requirements must also be met:
•
Gas furnaces must be installed by a licensed plumber
or gas fitter.
•
A T-handle gas cock must be used.
•
If the unit is to be installed in an attic, the passageway
to and the service area around the unit must have
flooring.
To ensure proper furnace operation, install, operate
and maintain the furnace in accordance with these
installation and operation 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/CSA
B149.1-15 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 obtained from any of the following:

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.

LOCATION REQUIREMENTS
& CONSIDERATIONS
Follow the instructions listed below and the guidelines
provided in the
Combustion and Ventilation Air
Requirements
section when selecting a furnace location.
WARNING
Possible property damage, personal injury or death due to
fire, explosion, smoke, soot, condensation, electrical shock
or carbon monoxide may result from improper installation,
repair operation, or maintenance of this product.
WARNING
To prevent possible equipment damage, property damage,
personal injury or death, the following bullet points must
be observed when installing this unit.
• 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.
•
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.
