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.

ONSIDERATIONS
Follow the instructions listed below and the guidelines
provided in the
Combustion and Ventilation Air Requirements
section when selecting a furnace location.
•
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.
•
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
