4. If you touch ungrounded objects (recharge your body with
static electricity), firmly touch furnace again before touching
control or wires.
5. Use this procedure for installed and uninstalled (ungrounded)
furnaces.
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 58MSA 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. The furnace is factory-shipped for use
with natural gas. An A.G.A/C.G.A certified gas conversion kit is
required to convert furnace for use with propane gas. These
furnaces are suitable for installation in a residence built on site or
a manufactured residence completed at final site. The design of
this furnace line is NOT A.G.A./C.G.A. certified for installation in
recreation vehicles, in manufactured (mobile) homes, or outdoors.
These furnaces SHALL NOT be installed directly on carpeting,
tile, or any other combustible material other than wood flooring. In
downflow installations, factory accessory floor base MUST be
used when installed on combustible materials and wood flooring.
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.

* ONLY supplied with some furnaces.
This furnace must be installed with a direct-vent (combustion air
and flue) system and a factory accessory termination kit. In a
direct-vent system, all air for combustion is taken directly from the
outside atmosphere and all flue products are discharged to the
outside atmosphere. See furnace and factory accessory termination
kit instructions for proper installation.
Before installing the furnace in the United States, refer to the
current edition of the NFGC and the NFPA 90B.
For copies of the NFGC and NFPA 90B contact the National Fire
Protection Association Inc., Batterymarch Park, Quincy, MA
02269; or American Gas Association, 1515 Wilson Boulevard,
Arlington, VA 22209.
Before installing the furnace in Canada, refer to the NSCNGPIC.
Contact Standard Sales, CSA International, 178 Rexdale Boule-
vard, Etobicoke, (Toronto) Ontario, Canada M9W 1R3.
Installation must comply with regulations of serving gas supplier
and local building, heating, plumbing or other codes in effect in the
area in which installation is made. In the absence of local codes,
installation must comply with the NFGC in the United States and
the NSCNGPIC in Canada.
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
Quantity

installed in any of the 4 applications shown in Fig. 1. All drain and
1
pressure tubes are connected as shown in Fig. 5. See appropriate

Step 2—Upflow Applications
2
An upflow furnace application is where furnace blower is located
1
below combustion and controls section of furnace, and conditioned
1*
air is discharged upwards.
CONDENSATE TRAP LOCATION (FACTORY-SHIPPED
ORIENTATION)
The condensate trap is factory installed in the blower shelf and
factory connected for UPFLOW applications. A factory-supplied
tube is used to extend the condensate trap drain connection to the
desired furnace side for field drain attachment. See Condensate
Trap Tubing (Factory-Shipped Orientation) section for drain tube
extension details.
