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 Model 58PAV, Series 141 Furnace is available in sizes 45,000
through 155,000 Btuh input capacities.
The design of the upflow gas-fired furnace is A.G.A./C.G.A.
certified for natural and propane gas and for installation on
combustible flooring, in alcoves, attics, basements, closets, or
utility rooms. The design of this furnace line is not A.G.A./C.G.A.
certified for installation in mobile homes, recreation vehicles, or
outdoors.
Before installing the furnace, refer to the current edition of the
NFGC. Canadian installations must be installed in accordance with
NSCNGPIC and all authorities having jurisdiction. For further
information, the NFGC is available from National Fire Protection
Association Inc., Batterymarch Park, Quincy, MA 02269; Ameri-
can Gas Association, 1515 Wilson Boulevard, Arlington, VA
22209; or from Literature Distribution.
Installation must conform to the regulations of the serving gas
supplier and the local building, heating, and plumbing codes in
effect in the area in which the installation is made, or in the
absence of local codes with the requirements of the NFGC.
Application of this furnace should be indoors with special
attention given to vent sizing and material, gas input rate, air
temperature rise, and unit sizing. Improper installation or
misapplication of the furnace can require excessive servicing
or cause premature component failure.
This furnace is designed for a minimum continuous return-air
temperature of 60°F db or an intermittent operation down to 55°F
db such as when used with a night setback thermostat. Return-air
temperature must not exceed a maximum of 85°F db.
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 can cause electrical shock, fire,
personal injury, or death.
For accessory installation details, refer to the applicable instruction
literature.
NOTE: Remove all shipping brackets and materials before oper-
ating the furnace.
Step 1—Location

GENERAL

Do not install furnace in a corrosive or contaminated atmo-
sphere. Make sure all combustion and circulating air require-
ments are met, in addition to all local codes and ordinances.
Do not use this furnace during construction when adhesives,
sealers, and/or new carpets are being installed. If the furnace
is required during construction, use clean outside air for
combustion and ventilation. Compounds of chlorine and
fluorine when burned with combustion air form acids which
cause corrosion of the heat exchangers and metal vent system.
Some of these compounds are found in paneling and dry wall
adhesives, paints, thinners, masonry cleaning materials, and
many other solvents commonly used in the construction
process.
This furnace must be installed so the electrical components are
protected from water. This furnace shall not be installed directly on
carpeting, tile, or any combustible material other than wood
flooring.
Locate furnace as close to the chimney/vent and as near the center
of the air distribution system as possible. The furnace should be
installed as level as possible.
When a furnace is installed so that the supply ducts carry air to
areas outside the space containing the furnace, the return air must
also be handled by a duct(s) sealed to the furnace casing and
terminating outside the space containing the furnace.
Provide ample space for servicing and cleaning. Always comply
with the minimum fire protection clearances shown on the unit
rating plate.
LOCATION RELATIVE TO COOLING EQUIPMENT — The
cooling coil must be installed parallel with or on the downstream
side of the unit to avoid condensation in the heat exchangers.
When installed parallel with a furnace, dampers or other means
used to control the flow of air must prevent chilled air from
entering the unit. If the dampers are manually operated, they must
be equipped with means to prevent operation of either unit unless
the damper is in the full-heat or full-cool position.
HAZARDOUS LOCATIONS — When the furnace is installed in
a residential garage, it must be installed so that the burners and
ignition source are located at least 18 in. above the floor. The
furnace should be protected from physical damage by vehicles.
When a furnace is installed in public garages, airplane hangars, or
other buildings having hazardous atmospheres, the unit must be
installed in accordance with the recommended good practice
requirements of the National Fire Protection Association, Inc.
Step 2—Air For Combustion and Ventilation
Provisions for adequate combustion and ventilation air must be
provided in accordance with Section 5.3 of the NFGC, Air for
Combustion and Ventilation, or applicable provisions of the local
building codes.
Canadian installations must be installed in accordance with NSC-
NGPIC and all authorities having jurisdiction.
