PERSONAL INJURY AND/OR PROPERTY DAMAGE
HAZARD
Improper use or installation of this furnace may result in
premature furnace component failure. This gas furnace
may be used for heating buildings under construction
provided that:
−The furnace is permanently installed with all electrical
wiring, piping, venting and ducting installed according to
these installation instructions. A return air duct is
provided, sealed to the furnace casing, and terminated
outside the space containing the furnace. This prevents
a negative pressure condition as created by the
circulating air blower, causing a flame rollout and/or
drawing combustion products into the structure.
−The furnace is controlled by a thermostat. It may not be
"hot wired" to provide heat continuously to the structure
without thermostatic control.
−Clean outside air is provided for combustion. This is to
minimize the corrosive effects of adhesives, sealers and
other construction materials. It also prevents the
entrainment of drywall dust into combustion air, which
can cause fouling and plugging of furnace components.
−The temperature of the return air to the furnace is
maintained between 55°F (13°C) and 80°F (27°C), with
no evening setback or shutdown. The use of the furnace
while the structure is under construction is deemed to be
intermittent operation per our installation instructions.
−The air temperature rise is within the rated rise range on
the furnace rating plate, and the gas input rate has been
set to the nameplate value.
−The filters used to clean the circulating air during the
construction process must be either changed or
thoroughly cleaned prior to occupancy.
−The furnace, ductwork and filters are cleaned as
necessary to remove drywall dust and construction
debris from all HVAC system components after
construction is completed.
−Verify proper furnace operating conditions including
ignition, gas input rate, air temperature rise, and venting
according to these installation instructions.
General
These furnaces are shipped with materials to assist in proper
furnace installation. These materials are shipped in the main
blower compartment.
See Table 2 for loose parts bag contents.
This furnace must:
• be installed so the electrical components are protected
from water.

air distribution system. Refer to Air Ducts section.
• be provided ample space for servicing and cleaning.
Always comply with minimum fire protection clearances
shown in Table 1 or on the furnace clearance to
combustible construction label.
CARBON MONOXIDE POISONING / COMPONENT
DAMAGE HAZARD
Failure to follow this warning could result in personal in-
jury or death and unit component damage.
Corrosive or contaminated air may cause failure of parts
containing flue gas, which could leak into the living
space. Air for combustion must not be contaminated by
halogen compounds, which include fluoride, chloride,
bromide, and iodide. These elements can corrode heat
exchangers and shorten furnace life. Air contaminants
are found in aerosol sprays, detergents, bleaches, clean-
ing solvents, salts, air fresheners, and other household
products. Do not install furnace in a corrosive or contam-
inated atmosphere. Make sure all combustion and circu-
lating air requirements are met, in addition to all local
codes and ordinances.
The following types of furnace installations may require
OUTDOOR AIR for combustion due to chemical exposures:
• Commercial buildings
• Buildings with indoor pools
• Laundry rooms
• Hobby or craft rooms, and
• Chemical storage areas
If air is exposed to the following substances, it should not be
used for combustion air, and outdoor air may be required for
combustion:
• Permanent wave solutions
• Chlorinated waxes and cleaners
Chlorine based swimming pool chemicals
•
Water softening chemicals
•
• De−icing salts or chemicals
• Carbon tetrachloride
• Halogen type refrigerants
• Cleaning solvents (such as perchloroethylene)
Printing inks, paint removers, varnishes, etc.
•
• Hydrochloric acid
• Cements and glues
• Antistatic fabric softeners for clothes dryers
• Masonry acid washing materials
All fuel−burning equipment must be supplied with air for fuel
combustion. Sufficient air must be provided to avoid negative
pressure in the equipment room or space. A positive seal must
be made between the furnace cabinet and the return−air duct
to prevent pulling air from the burner area.
