applications. It is NOT
designed or certified for use in mobile
homes, trailers or recreational vehicles. Neither is it designed
or certified for outdoor applications. The furnace
must
be
installed indoors (i.e., attic space, crawl space, or garage area
provided the garage area is enclosed with an operating door).
This furnace can be used in the following non-industrial com-
mercial applications:
Schools, Office buildings, Churches, Retail stores,
Nursing homes, Hotels/motels, Common or office areas
In such applications, the furnace must be installed with the
following stipulations:

on site.
•
It must be part of a ducted system and not used in a
free air delivery application.
•
It must not be used as a “make-up” air unit.
•
All other warranty exclusions and restrictions apply.
This furnace may be used as a construction site heater
ONLY
if 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.
•
100% outside air must be used for combustion during
construction. Temporary ducting may be used to
supply outside air to the furnace for combustion – do
not connect this duct directly to the furnace. Size this
duct according to NFPA 54/ANSI Z223.1 section for
Combustion and Ventilation Air.
•
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 re-
quirements are not covered under the warranty.
