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 drywail 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 1 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
2 or on the furnace clearance to combustible construction label.

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, 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 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
* 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.

FIRE, INJURY OR DEATH HAZARD
Failure to follow this warning could result in personal
injury,
death
and/or
property
damage.
When the furnace is installed in a residential garage, the
burners and ignition sources must be located at least 18 in.
(457 mm) above the floor. The furnace must be located or
protected to avoid damage by vehicles. When the furnace is
installed in a public garage, airplane hangar, or other
building having a hazardous atmosphere, the furnace must
be installed in accordance with the NFPA 54/ANSI
Z223.1-2009 or CAN/CSA B149.2-2010. See Fig. 5.
