This furnace is primarily designed for residential home-heating 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 commercial applications:
In such applications, the furnace must be installed with the following stipulations:
• It must be installed per the installation instructions provided and per local and national codes.
• It must be installed indoors in a building constructed 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.
This product is dual certified. 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 instructions.
• All other warranty exclusions and restrictions apply This furnace is an ETL dual-certified appliance and is appropriate for use
with natural or propane gas (NOTE: If using propane, a propane conversion kit is required).
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.
• 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 during construction replaced as appropriate during construction, and
upon completion of construction.
• The input rate and temperature rise are set per 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 final
construction clean up.
