SYSTEM OPERATION
8
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, us
-
ing 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 installa-
tion 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 Con
-
tractors of America.

WARNING
•
Centrally locate the furnace with respect to the pro
-
posed 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 termina
-
tion 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.
