6. Before removing a new control from its container, discharge
your body's electrostatic charge to ground to protect the
control from damage. If the control is to be installed in a
furnace, follow items 1 through 5 before bringing the control
or yourself into 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.

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.

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.

NOTE: See Fig. 5 or tube routing label on main furnace door to
confirm location of these tubes.
1. Collector Box Drain, Inducer Housing Drain, Relief Port, and
Pressure Switch Tubes
These tubes should be factory attached to condensate trap and
pressure switch ready for use in UPFLOW applications. These
tubes can be identified by their connection location and also
by a color label on each tube. These tubes are identified as
follows: collector box drain tube (blue label), inducer housing
drain tube (violet label or molded), relief port tube (green
label), and pressure switch tube (pink label).
2. Condensate Trap Drain Tube
The condensate trap drain connection must be extended for
field attachment by doing the following:
a. Determine location of field drain connection. (See Fig. 2 or
5.)
