SAFETY CONSIDERATIONS

Installing and servicing heating equipment can be hazardous due to
gas and electrical components. Only trained and qualified person-
nel should install, repair, or service heating equipment. Untrained
personnel can perform basic maintenance functions such as clean-
ing and replacing air filters. All other operations must be per-
formed by trained service personnel. When working on heating
equipment, observe precautions in literature, on tags, and on labels
attached to or shipped with unit and other safety precautions that
may apply.
Follow all safety codes. In the United States, follow all safety
codes including the National Fuel Gas Code (NFGC) NFPA No.
54-1992/ANSI Z223.1-1992. In Canada, refer to the current
edition of the National Standard of Canada CAN/CGA-B149.1-
and .2-M91 Natural Gas and Propane Installation Codes (NSC-
NGPIC). Wear safety glasses and work gloves. Have fire extin-
guisher available during start-up and adjustment procedures and
service calls.
Recognize safety information. This is the safety-alert symbol
When you see this symbol on unit or in instructions and manuals,
be alert to potential for personal injury.
Understand the signal words DANGER, WARNING, and CAU-
TION. These words are used with safety-alert symbol. DANGER
identifies most serious hazards which will result in severe personal
injury or death. WARNING signifies hazards which could result in
personal injury or death. CAUTION is used to identify unsafe
practices which would result in minor personal injury or product
and property damage. NOTE is used to highlight suggestions
which will result in enhanced installation, reliability, or operation.

INTRODUCTION

The 58MVP Multipoise Condensing Gas-Fired Furnaces are
A.G.A./C.G.A. certified for natural and propane gases and for
installation in alcoves, attics, basements, closets, utility rooms,
crawlspaces, and garages.
These furnaces SHALL NOT be installed directly on carpeting,
tile, or any other combustible material other than wood flooring. In
downflow installations, accessory floor base MUST be used when
installed on combustible materials and wood flooring. The design
of this furnace line is not A.G.A./C.G.A. certified for installation
in mobile homes, recreation vehicles, or outdoors. These furnaces
are suitable for installation in a residence built on site or a
manufactured residence completed at final site.
These furnaces are shipped with the drain and pressure tubes
connected for UPFLOW applications. Minor modifications are
required when used in DOWNFLOW, HORIZONTAL RIGHT, or
HORIZONTAL LEFT (supply-air discharge direction) applica-
tions as shown in Fig. 1. See details in Applications section.
These furnaces are shipped with the following materials to assist in
proper furnace installation. These materials are shipped in the main
blower compartment.
Installer Packet includes:
Installation, Start-Up, and Operating Instructions
Service and Maintenance Instructions
User's Information Manual
Warranty Certificate
Loose Parts Bag includes:
Pressure tube extension
Collector box or condensate trap extension tube
Inducer housing drain tube
1/2-in. CPVC street elbow
Drain tube coupling
Drain tube coupling grommet
Vent and combustion-air pipe support
Combustion-air pipe perforated disk assembly
Before installing the furnace in the United States, refer to the
current edition of the NFGC. For further information, the NFGC is
available from National Fire Protection Association Inc., Battery-
march Park, Quincy, MA 02269, American Gas Association, 1515
Wilson Boulevard, Arlington, VA 22209, or from Literature
Distribution.
Before installing the furnace in Canada, refer to the current edition
of the NSCNGPIC. Contact Standards Department of Canadian
Gas Association, 55 Scarsdale Road, Don Mills, Ontario, Canada
M3B 2R3.
Installations must comply with regulations of serving gas supplier
and local building, heating, plumbing, or other codes in effect in
area in which installation is made. In absence of local codes,
installation must conform with NFGC.
Canadian installations must be made in accordance with NSCNG-
PIC and all authorities having jurisdiction.
These instructions cover minimum requirements for a safe instal-
lation and conform to existing national standards and safety codes.
.
In some instances, these instructions exceed certain local codes
and ordinances, especially those that may not have kept pace with
changing residential construction practices. We require these
instructions as a minimum for a safe installation.
Application of this furnace should be indoors with special
attention given to vent sizing and material, gas input rate, air
temperature rise, unit leveling, and unit sizing. Improper
installation or misapplication of furnace can require excessive
servicing or cause premature component failure.
Improper installation, adjustment, alteration, service, mainte-
nance, or use can cause carbon monoxide poisoning, explo-
sion, fire, electrical shock, or other conditions which may
cause personal injury or property damage. Consult a qualified
installer, service agency, local gas supplier, or your distribu-
tor or branch for information or assistance. The qualified
installer or agency must use only factory-authorized and
listed kits or accessories when modifying this product. Failure
to follow this warning could result in electrical shock, fire,
personal injury, or death.
For accessory installation details, refer to applicable installation
literature.
Step 1—General
Some assembly and modifications are required for furnaces
installed in any of the 4 applications shown in Fig. 1. All drain and
pressure tubes are connected as shown in Fig. 5. See appropriate
application instructions for these procedures.
Step 2—Upflow Applications
An upflow furnace application is where furnace blower is located
below combustion and controls section of furnace and conditioned
air is discharged upwards.
