All other warranty exclusions and restrictions apply This
furnace is an ETL dual-certified appliance and is appropri-
ate for use with natural or propane gas (
NOTE:
If 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:
Non-direct 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,
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 in-
structions.
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 in-
stallation 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 (16ºC) and
80ºF (27ºC) is maintained.
•
Air filters are installed in the system and maintained dur-
ing construction replaced as appropriate during construc-
tion, and upon completion of construction.
•
The input rate and temperature rise are set per the fur-
nace rating plate.
•
100% outside air is provided for combustion air require-
ments 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 combus-
tion 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 fol-
lowing 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 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 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 Calcula-
tions” published by the Air Conditioning Contractors of America.
