• A return air temperature range between 60ºF (16ºC) and 80ºF (27ºC) is maintained.
• Air filters are installed in the system and maintained during construction replaced as appropriate during construction, and
upon completion of construction.
• The input rate and temperature rise are set per the furnace rating plate.
• 100% outside air is provided for combustion air requirements during construction. Temporary ducting can be used.
NOTE: Do not connect the temporary duct directly to the furnace. The duct must be sized for adequate combustion and
ventilation in accordance with the latest edition of the National Fuel Gas Code NFPA 54/ANSI Z223.1 or CAN/CSA B149.1
Installation Codes.
• The furnace heat exchanger, components, duct system, air filters and evaporator coils are thoroughly cleaned following final
construction clean up.
• All furnace operating conditions (including ignition, input rate, temperature rise and venting) are verified according to
these installation instructions.
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.

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
