The model 58MXA is a must for your
product line. This high-efficiency
furnace allows more applications with
its reliable 4-way multipoise design.
The model 58MXA is available in 12
heat/airflow combinations and with the
4-way multipoise design can be
installed in upflow, downflow, or
horizontal positions covering up to 48
different applications. With the
exception of the 140 size unit, all
58MXA models can be installed in a
manufactured (mobile) home when the
optional kit is used. The furnace is
factory configured for upflow
application.
This versatile unit utilizes hot surface
ignition (HSI) which ignites the burners
directly. HSI eliminates gas waste that
typical continuous-pilot designs can
bring. Hot surface ignition provides
reliable start-up and operation.
Take a look at the control center on
model 58MXA. Control of ignition,
inducer, and blower operation is all
handled in 1 central printed circuit
board. The status indicator on the
control signals when a fault has
occurred and identifies where the
problem is. This, along with the
component test feature, makes the
58MXA one of the easiest gas furnaces
to troubleshoot.
High efficiency is achieved by
maximizing heat transfer. The model
58MXA uses 100 percent outdoor air
for combustion in a sealed-combustion
system. The result is energy-saving
efficiency, up to 95.5 percent (Pg. 12)
Annual Fuel Utilization Efficiency
(AFUE), and reduced operational noise.
The model 58MXA is one of the
quietest furnaces in the industry.
A unique feature of this unit is the
patented polypropylene-laminated
heat exchanger. This secondary heat

reason. The slow opening feature reduces
start-up noise from rapid ignition.
Quality Registration — The 58MXA
is engineered and manufactured under an
ISO 9001 registered quality system.
Insulation — Foil-faced insulation in
heat exchanger section of the casing
minimizes heat loss.
Control Center — Microprocessor
controls sequencing and furnace
operation. Equipped with a component
test feature and status indicator light
to assist in troubleshooting. Selectable
micro-processor blower control times

to eliminate cold air blowing into rooms.
Adjustable Blower Speed — For
precise airflow selection of heating or
cooling operation.
Direct-Vent Sealed Combustion
System — Model 58MXA uses 100
percent outdoor air, which results in
especially quiet operation. Direct
venting minimizes the possibility of
chloride contamination which can result
in heat exchanger corrosion. Direct
venting also reduces air infiltration into
the home.

58MXA FEATURES/
BENEFITS
Insulated Blower Compartment —
The acoustical insulation reduces air and
motor noise to promote quiet operation.
Certifications — The 58MXA units
are A.G.A. and C.G.A. design certified
for use with natural and propane gases.
The furnace is factory-shipped for use
with natural gas. An A.G.A./C.G.A.
listed gas conversion kit is required to
convert furnace for use with propane
gas. The efficiency is GAMA
efficiency rating certified. The 58MXA
meets California Air Quality
Management District emission
requirements. Except for the 140 size
unit, all 58MXA models can be
installed in a manufactured (mobile)
home when the optional kit is used.
W
exchanger ensures that all available heat
is properly transferred to the airstream
and throughout the home. Using the
exclusive flow-through design, the
secondary heat exchanger reduces the
pressure drop in the furnace which leads
to lower electrical usage, an important
part of this unit’s efficiency. Carrier heat
exchangers are backed by a Limited
Lifetime Warranty. (See Warranties
section for details.)
When we put it all together, the model
58MXA combines quality and design to

A concentric vent kit allows vent
and combustion-air pipes to
terminate through a single exit
in a roof or side wall.
One base fits all furnace sizes.
The base is designed to be installed between the furnace and a
combustible floor when no coil
box is used or when a coil box
other than a Carrier cased coil is
used. It is A.G.A./C.G.A. design
certified for use with Carrier

Saves decorating and cleaning
expenses by keeping carpets,
furniture, and drapes cleaner.
By adding moisture to winterdry air, a Carrier humidifier can
often improve comfort and keeps
woodwork, wallpaper, and paint
in better condition. Moisturizing
household air also helps to retain
normal body heat and provides
comfort at lower temperatures.
Available in programmable and
non-programmable models,
Carrier thermostats maintain a
constant, comfortable temperature level in the home.
Carrier’s energy or heat recovery
ventilators exhaust stale indoor
air and provide fresh outdoor air
to the home while minimizing
heat loss and humidity level.
Especially useful for today’s
tighter constructed houses.
Electronic air cleaner is shown.
For the ultimate in home comfort, Carrier’s 2, 4 and 8-zone
systems allow temperature control of individual “zones” of the
home. This is accomplished
through a series of electronic
dampers and remote room
sensors. The 4-zone system is

* Disk usage—Unless otherwise specified, use perforated disk assembly (factory-supplied in loose parts bag). If 1 disk is stated, separate 2 halves of
perforated disk assembly and use shouldered disk half. When using shouldered disk half, install screen side toward inlet box.
† Wide radius elbow.
‡ Vent sizing for Canadian installations over 4500 ft (1370m) above sea level are subject to acceptance by the local authorities having jurisdiction.
NA — Not Allowed; pressure switch will not make.
NOTES:
1. Do not use pipe size greater than those specified in table or incomplete combustion, flame disturbance, or flame sense lockout may occur.
2. Size both the combustion-air and vent pipe independently, then use the larger diameter for both pipes.
3. Assume two 45° elbows equal one 90° elbow. Long radius elbows are desirable and may be required in some cases.
4. Elbows and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.
5. The minimum pipe length is 5 ft for all applications.
6. Use 3 in. diameter vent termination kit for installations requiring 4 in. diameter pipe.
