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
Table 2
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
Table 1
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 containing flue
gas, which could leak into the living space. Air for combustion must not
be contaminated by halogen compounds, which include fluoride, chlor-
ide, 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 contaminated
atmosphere. Make sure all combustion and circulating 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.
