• Damage or repairs due to failure to comply with these requirements is 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 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.

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.
