CAUTION
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
for loose parts bag contents.
This furnace must:
•
be installed so the electrical components are protected
from water.
•
not be installed directly on any combustible material other
than wood flooring (refer to SAFETY
CONSIDERATIONS).
•
be located close to the chimney or vent and attached to an
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
or on the furnace clearance to
combustible construction label.

WARNING
CARBON MONOXIDE POISONING / COMPONENT
DAMAGE HAZARD
Failure to follow this warning could result in personal injury or
death and unit component damage.
Corrosive or contaminated air may cause failure of parts con-
taining 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, cleaning solvents, salts, air fresheners, and other
household products. Do not install furnace in a corrosive or con-
taminated atmosphere. Make sure all combustion and circulat-
ing 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.
