Product Data
4-Way Multipoise Design
Allows More Applications . . .
A05069
The Performance™ 93 is a must for
your product line. This high-efficiency
furnace allows more applications with
its reliable 4-way multipoise design.
The Performance™ 93 is available in 6
heat/airflow combinations and with the
4-way multipoise design can be
installed in upflow, downflow, or
horizontal positions. The furnace is
factory configured for upflow
application. The versatility of this
furnace is further enhanced by its dual
venting capability. The Performance™
93 can be installed as 1-pipe/Non-Direct
vent or 2-pipe/Direct Vent.
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
the Performance™ 93. Control of
ignition, inducer, and blower operation
is all handled in 1 central printed circuit
board. The status indicator on the
control signals when an event has
occurred and identifies where the event
is. This, along with the component test
feature, makes the Performance™ 93
one of the easiest gas furnaces to
troubleshoot.
A unique feature of this unit is the
patented polypropylene-laminated
heat exchanger. This secondary heat
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.)
THE PERFORMANCE™ 93
FEATURES/BENEFITS
ComfortHeat™ Technology—The
Performance™ 93 has a 2-stage gas
valve to vary the amount of gas being
used from low-heat to high-heat stage.
The low-stage operation allows longer
running periods, which helps maintain
your most comfortable temperature,
prevents drafts, reduces noise, and
enhances the air quality of your home.
During the extreme cold, the high-heat
levels will run to ensure that you are still
comfortable.
Primary Heat Exchanger &
Serpentuff™ Secondary Heat
Exchanger — The primary heat
exchanger is corrosion resistant and
maintains a proven track record for longterm reliability and high-efficiency
performance. The secondary heat
exchanger is built with a patented
lamination process that bonds a
corrosion-proof lining of polypropylene
to a heavy, galvanized steel shell. The
unique secondary clamshell design
allows wider spacing between cells for
reduced air resistance through the
furnace, reduced load on the blower
motor, and reduced need for cleaning.
Power Heat™ Igniter — Carrier’s
unique SiN igniter is not only physically
robust but it is also electrically robust. It is
capable of running at line voltage and
does not require complex voltage
regulators as do other brands. This unique
feature further enhances the reliability of
Performance™ 93 gas furnace and
continues Carrier’s tradition of
technology leadership and innovation in
providing a reliable and durable product.
ComfortFan™ — Improves comfort
all year long by allowing the
homeowner to select different fan
speeds during continuous fan operation
to achieve more or less airflow. This is
done right at the thermostat.
SmartEvap™ — This feature allows
your system to reduce summer time
humidity levels by nearly 10% over
standard systems.
Media Filter Cabinet — Enhanced
indoor air quality in your home is made
easier with our media filter cabinet—a
standard accessory on all furnaces.
When installed as a part of your system,
this cabinet allows for an easy and
convenient addition of a Carrier highefficiency air filter.
Adaptive Logic Control Board — This
self-adjusting control board contains a
microprocessor which automatically
calculates the precise amount of time
your furnace should run and whether it
should run in low-heat or high-heat
operation to obtain the best comfort and
energy efficiency. This control board
also includes an extensive
troubleshooting and component test
sequence that can monitor your heating
system to ensure that it is operating
properly.
SETUP SWITCHES
LOW-HEAT ONLY AND
BLOWER OFF-DELAY
4-Way Multipoise Design — Allows
the Performance™ 93 to be installed in
an upflow, downflow, or horizontal
orientation. Factory configured for
upflow applications with only simple
drain connection changes required for
conversion to downflow or horizontal.
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.
5 year Limited Warranty on entire unit.
Contact your dealer for details.
Direct or Non-Direct Venting — The
Performance™ 93 can be installed as a 1
pipe/Non-Direct vent or 2 pipe/Direct
vent furnace. This provides added
flexibility to meet diverse installation
needs.
Two-Speed Inducer Motor — This
motor works with the inducer fan to
optimize combustion efficiency and
exhaust the flue gases out of the house.
The motor has two speeds and an
incorporated fan to keep the motor cool
while reducing sound.
Permanent split capacitor (PSC)
Blower Motor — The Performance™
93 has a PSC blower motor that has
several preselected fixed speeds which
can be customized to duct work
installation requirements. The motor has
a wide application of use, a basic control
scheme, and is extremely reliable.
Full Cabinet Insulation — This
insulation completely surrounds the
internal furnace casing allowing for
reduced and dampened sounds and
maintained efficiencies.
Soft Motor Mounts — These motor
mounts help to absorb shock, decrease
the vibration of the motor, and minimize
noise.

Airflow shown is with factory supplied 1-in. washable filter.
A filter is required for each return air opening.
An airflow reduction of up to 7% may occur when using the factory-specified 4-5/16-inch wide, high efficiency media filter.
For best furnace efficiency when using the 4 5/16-inch wide media filter, adjust blower speed tap to near the mid-point of the rise range.
For horizontal and downflow applications, use “1 side or bottom” or “bottom only” as airflow reference.

*Disk usage-Unless otherwise specified, use perforated disk assembly (factory-supplied in loose parts bag). If one 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 (1370 m) 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. Wide 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.
