This furnace is an ETL dual-certified appliance and is appropriate
for use with Natural or propane gas
NOTE: If you are using propane, a propane conversion kit is
required.
Dual certification means that the combustion air inlet pipe is
optional, and the furnace can be vented as a:
■
Nondirect vent (single pipe) central forced air furnace in
which combustion air is taken from the installation area or
from air ducted from the outside or a,
■
Direct vent (dual pipe) central forced air furnace in which all
combustion air supplied directly to the furnace burners
through a special air intake system outlined in these
instructions.
This furnace may be used as a construction site heater only if all
of the following conditions are met:
■
The vent system is permanently installed according to these
installation instructions.
■
A room thermostat is used to control the furnace. Fixed
jumpers that provide continuous heating cannot be used and
can cause long term equipment damage.
■
Return air ducts are provided and sealed to the furnace.
■
A return air temperature range between 60ºF and 80ºF (16ºC
and 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 according to 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
the final construction cleanup.
■
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 installation and operation, thoroughly read
this manual for specifics pertaining to the installation and
application of this product.
To ensure proper furnace operation, you must 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.
LOCATION REQUIREMENTS AND
CONSIDERATIONS
Follow the instructions listed below when selecting a furnace
location. Refer also to the guidelines provided in “Combustion
and Ventilation Air Requirements.”
■
Centrally locate the furnace with respect to the proposed or
existing air distribution system.
■
Check that the temperature of the return air entering the
furnace is between 55°F and 100°F (13ºC and 38ºC) when the
furnace is heating.
■
Provide provisions for venting combustion products outdoors
through a proper venting system. Special consideration
should be given to the vent/flue pipe routing and the
combustion air intake pipe when applicable. Refer to
“Termination Locations” in “Vent/Flue Pipe and Combustion
Air Pipe” for appropriate termination locations and to
determine if the piping system from the furnace to the
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.
