•
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.
Gas furnaces manufactured on or after May 1, 2017 are not
permitted to be used in Canada for heating of buildings or
structures under construction.
In the U.S.A. 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 per 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. Bi-metal
thermostats, or any thermostat affected by vibration
must not be used during construction.
•
Return air ducts are provided and sealed to the furnace.
•
A return air temperature range between 60÷F (16÷C)
and 80÷F (27÷C) is maintained.
•
Air filters are installed in the system and replaced daily
during construction and upon completion of construction.
•
The input rate and temperature rise are set per the
furnace rating plate.
•
The furnace must be installed as a two pipe system, using
100% outside air for combustion during construction.
•
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)

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.
A copy of the CAN/CSA B149.1-15 Installation Codes can also
