58MSA
4-Way Multipoise
Fixed-Capacity Condensing
Gas Furnace
Series 110
Input Capacities: 40,000 thru 120,000 Btuh
*High Efficiency and
Flexibility Designed to Meet
the Needs of New Homes
The model 58MSA combines high
efficiency with flexibility to meet the
changing needs of new home
construction. The unique 4-way,
multipoise design of the 58MSA
allows for installation in upflow,
downflow, horizontal left, and
horizontal right orientations,
meaning it is perfect for a variety
of installation applications. The
furnace is factory configured for
upflow application but can easily be
made ready for downflow or
horizontal installation.
Horizontal applications offer the
advantage of reduced space
requirements by locating the furnace
in an attic or crawlspace, freeing
space formerly dedicated to a furnace
or utility room.
The 58MSA is specifically
designed to meet the needs of home
builders and new home owners.
Home builders benefit from the
58MSA’s unmatched flexibility and
by building a reputation of using
quality appliances in homes. Home
owners benefit by energy savings
from 1 of the most important home
appliances.
The components of the 58MSA
represent the finest in the industry.
Hot surface ignition (HSI) and an
integrated control center provide
reliable and efficient ignition. The
inducer and inducer motor are unique
in that efficient operation is achieved
in any type of installation. Standard
PVC pipe is used to provide
combustion air to the furnace and

vent the exhaust outdoors. The
primary and secondary heat
exchangers are backed by a 20-year
Limited Warranty.
The 58MSA is a standard part of a
quality-built new home. This highefficiency furnace will provide years
of quality service to home builders
and home owners alike.
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.
58MSA FEATURES/
BENEFITS
Slow Opening Redundant Gas
Valve — The slow opening feature
reduces start-up noise from rapid
ignition.
Insulation — Foil-faced insulation in
heat exchanger section of the casing
minimizes heat loss.
Integrated Control Center —
Controls sequencing and furnace
operation. Equipped with a component
test feature and status indicator light to
assist in troubleshooting. 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.
Monoport Burners — The burners
are finely tuned for smooth, quiet
combustion plus economical gas
usage.
Serpentuff™ — Exclusive Serpentuff
coating, a patented polypropylene
laminate is used on the secondary heat
exchanger.
24V
COM W Y R G
Casing — One piece, seamless wraparound construction of heavy,
prepainted galvanized steel resists
corrosion.
Certifications — The 58MSA 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.
certified gas conversion kit is required
to convert furnace for use with propane
gas. The efficiency is GAMA
efficiency rating certified. The 58MSA
meets California Air Quality
Management District emission
requirements.
Warranties — 20-year Limited
Warranty on the heat exchangers.
One-year Warranty on integrated
control center, HSI, and inducer motor.
Contact your dealer for details.
Combustion Air and Venting — This
furnace uses combustion air from an
area adjacent to the furnace and brings
it in through a short section of inlet
pipe that terminates just outside of the
cabinet. The vent pipe can terminate
through a sidewall or through the
roof.
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 ignition
problems.

† Gas input ratings are certified for elevations to 2000 ft. For elevations above 2000 ft, reduce ratings 2% for each 1000 ft above sea level. In Canada, derate
the unit 10% for elevations 2000 to 4500 ft above sea level.
‡ Air delivery above 1800 CFM requires that both sides, or a combination of 1 side and bottom, or bottom only of the furnace be used for return air. Where 2
sets of data are listed, the first set is for bottom only return-air supply. The second set is for both sides, or 1 side and bottom return-air supply. A filter is
required for each return-air supply.

† Vent sizing for Canadian installations above 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. Assume two 45° elbows equal one 90° elbow. Long radius elbows are desirable and may be required in some cases.
3. Elbows and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.
4. The minimum pipe length is 5 ft for all applications.

Clearance to combustibles
This forced air furnace is equipped for use with natural gas at altitudes 0 - 10,000 ft (0 - 3,050m), except 140 size
Furnaces are only approved for altitudes 0 - 7,000 ft. (0 - 2,135m).
An accessory kit, supplied by the manufacturer, shall be used to convert to propane gas use or may be required for
some natural gas applications.
This furnace is for indoor installation in a building constructed on site. This furnace may be installed in a manufactured
(mobile) home when stated on rating plate and using factory authorized kit.
This furnace may be installed on combustible flooring in alcove or closet at minimum clearance from combustible
material.
This appliance requires a special venting system. Refer to the installation instructions for parts list and method of
installation. This furnace is for use with schedule-40 PVC, PVC-DWV, or ABS-DWV pipe, and must not be vented in
common with other gas-fired appliances. Construction through which vent/air intake pipes may be installed is maximum
24 inches (600 mm), minimum 3/4 inches (19 mm) thickness (including roofing materials).
*
††
Mimimum front clearance for service 30
inches (762mm).
140 size furnaces require 1 inch back
clearance to combustible materials.
This furnace is approved for UPFLOW, DOWNFLOW and
HORIZONTAL installations.
