damage. If the control is to be installed in a furnace, follow items 1
through 4 before bringing the control or yourself in contact with the
furnace. Put all used and new controls into containers before
touching ungrounded objects.
7. An ESD service kit (available from commercial sources) may also
be used to prevent ESD damage.
ACCESSORIES
See Product Data Sheet for a list of accessories for this product.
LOCATION
General
These furnaces are shipped with materials to assist in proper furnace
installation. These materials are shipped in the main blower
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.
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.
CAUTION
!
PERSONAL INJURY AND/OR PROPERTY DAMAGE
HAZARD
Improper use or installation of this furnace may result in premature
furnace component failure. Unless otherwise prohibited, 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.
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,
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.
