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
bring high efficiency and comfort. You
will enjoy the versatility and ease of
installation of this unit. The model
58MXA is equipped for either left- or
right-side connections. Blower speeds
are easily adjustable with speed-taps
conveniently located on the control
center. An updated, more efficient
combustion inducer allows for more use
of 2-in. vent and combustion-air piping,
keeping installation costs low.
As with other Carrier furnaces, this
model is designed to work as a part of the
total home comfort system which
includes elements for cooling, air
cleaning, humidification, ventilation,
and zoning.

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.
Warranties — Limited Lifetime
Warranty on the heat exchangers for the
lifetime of original owner in single
family residence; 20 years in other
residential and commercial applications.
Three-year Limited Warranty on
microprocessor control, HSI, and
inducer motor. One year Limited
Warranty on entire unit. Contact your
dealer for details.
Combustion Products Venting —
The combustion-air and vent pipes can
terminate through a side wall or
through the roof when used with a
factory-authorized vent termination kit.
Blower Access Panel Switch — Shuts
off all 115-v power through furnace
components whenever blower access
panel is opened.
Hot Surface Ignitor — No pilot flame
to waste gas or cause problems.
Slow Opening Redundant Gas Valve
— Shuts off gas to burners if 1 of the
valves fails to close completely for any

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
blower start after main burners ignite
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.
Monoport Burners — The burners
are finely tuned for smooth, quiet
combustion plus economical gas usage.

coating, a patented polypropylene
laminate is used on the secondary heat
exchanger.
Bottom Closure — Factory-installed
for side return; easily removable for
bottom return.
Filter — Cleanable filter with retainer
is standard.
