58TP0A/58TP1A: Installation, Start-up, Operating and Service and Maintenance Instructions

LOCATION

GENERAL

This multipoise furnace is shipped in packaged configuration. Some
assembly and modifications are required when used in any of four
applications (as shown in Fig. 6).
Fig. 6 – Multipoise Orientations
NOTE: For high-altitude installations, the high-altitude conversion kit
MUST be installed at or above 5500 ft. (1676 M) above sea level.
Obtain high-altitude conversion kit from your area authorized
distributor.
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 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, 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 and from draft safeguard opening.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
FURNACE CORROSION HAZARD
Failure to follow this caution may result in furnace damage.
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.

AIR FOR COMBUSTION AND VENTILATION

Provisions for adequate combustion, ventilation, and dilution air must be
provided in accordance with:
• U.S. Installations: Section 9.3 of the NFPA 54/ANSI Z223.1, Air for
A02097
Combustion and Ventilation and applicable provisions of the local
building codes.
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury or death.
The operation of exhaust fans, kitchen ventilation fans, clothes dryers,
attic exhaust fans or fireplaces could create a NEGATIVE PRESSURE
CONDITION at the furnace. Make-up air MUST be provided for the
ventilation devices, in addition to that required by the furnace. Refer to
the Carbon Monoxide Poisoning Hazard warning in the venting section
of these instructions to determine if an adequate amount of make-up air
is available.
The requirements for combustion and ventilation air depend upon
whether or not the furnace is located in a space having a volume of at
least 50 cubic feet per 1,000 Btuh input rating for all gas appliances
installed in the space.
• Spaces having less than 50 cubic feet per 1,000 Btuh require the
OUTDOOR COMBUSTION AIR METHOD.
• Spaces having at least 50 cubic feet per 1,000 Btuh may use the
INDOOR COMBUSTION AIR, STANDARD or KNOWN AIR
INFILTRATION METHOD.
Outdoor Combustion Air Method
1. Provide the space with sufficient air for proper combustion,
ventilation, and dilution of flue gases using permanent horizontal or
vertical duct(s) or opening(s) directly communicating with the
outdoors or spaces that freely communicate with the outdoors.
2. Fig. 7 illustrates how to provide TWO OUTDOOR OPENINGS,
one inlet and one outlet combustion and ventilation air opening, to
the outdoors.
a. One opening MUST commence within 12 in. (300 mm) of the
ceiling and the second opening MUST commence within 12 in.
(300 mm) of the floor.
b. Size openings and ducts per
c. TWO HORIZONTAL DUCTS require 1 sq. in. (645 sq. mm) of
free area per 2,000 Btuh (1,100 mm2/kW) of combined input for
all gas appliances in the space per
d. TWO OPENINGS OR VERTICAL DUCTS require 1 sq. in.
(645 sq. mm) of free area per 4,000 Btuh (550 mm2/kW) for
combined input of all gas appliances in the space per
Table 1.
3. ONE OUTDOOR OPENING requires:
a. 1 sq. in. (645 sq. mm) of free area per 3,000 Btuh (734 mm2/kW)
for combined input of all gas appliances in the space per
and
b. Not less than the sum of the areas of all vent connectors in the
space.
