FEATURES AND BENEFITS
HYBRID HEATR Dual Fuel System — This system can provide
more control over your monthly energy bills by automatically
selecting the most economical method of heating. With HYBRID
HEAT components, our system automatically switches between the
gas furnace and the single--stage electric heat pump as outside
temperatures change to maintain greater efficiency and comfort
than with any traditional single-source heating system. The heat
pump also delivers high-efficiency cooling in the summer.
Power Heatt 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 gas furnace reliability and continues Carrier’s tradition of
technology leadership and innovation in providing a reliable and
durable product.
Reliable Heat Exchanger Design — The aluminized steel, clam
shell primary heat exchanger was re--engineered to achieve greater
efficiency out of a smaller size. The first two passes of the heat
exchanger are based on the current 80% product, a design with
more than ten years of field-proven performance and success.
These innovations, paired with the continuation of a crimped,
no-weld seam create an efficient, robust design for this essential
component.
The condensing heat exchanger, a stainless steel fin and tube
design, is positioned in the furnace to extract additional heat.
Stainless steel coupling box componentry between heat exchangers
has exceptional corrosion resistance in both natural gas and
propane applications.
4-Way Multipoise Design — One model for all applications –
there is no need to stock special downflow or horizontal models
when one unit will do it all. The new heat exchanger design allows
these units to achieve the certified AFUE in all positions.
Direct or Single-pipe Venting, or Optional Ventilated
Combustion Air — This furnace can be installed as a 2-pipe
(Direct Vent) furnace, in an optional ventilated combustion air
application, or in single-pipe, non-direct vent applications. This
provides added flexibility to meet diverse installation needs.
Sealed Combustion System — This furnace brings in combustion
air from outside the furnace, which results in especially quiet
operation. By sealing the entire combustion vestibule, the entire
furnace can be made quieter, not just the sound of the burners.
Monoport Burners — The burners are specially designed and
finely tuned for smooth, quiet combustion and economical
operation.
Bottom Closure — Factory-installed for side return; easily
removable for bottom return. The multi-use bottom closure can
also serve for roll-out protection in horizontal applications, and act
as the bottom closure for the optional return air base accessory.
Blower Access Panel Switch — Automatically shuts off 115-v
power to furnace whenever blower access panel is opened.
Quality Registration — Our furnaces are engineered and
manufactured under an ISO 9001 registered quality system.
Certifications — This furnace is CSA (AGA and CGA) design
certified for use with natural and propane gases. The furnace is
factory--shipped for use with natural gas. A CSA listed gas
conversion kit is required to convert furnace for use with propane
gas. The efficiency is AHRI efficiency rating certified. This furnace
meets California Air Quality Management District emission
requirements.

NOTE:
1. A filter is required for each return ---air inlet. Airflow performance includes a 3/4 ---in. (19 mm) washable filter media such as contained in a factory ---authorized accessory filter rack. See accessory list. To determine airflow performance without this filter, assume an additional 0.1 in. w.c.. available external static
pressure.
2. Blower speed taps are not always in the same order. Factory default blower connections are as follows:
a. Heating airflow --- BLUE (also used for Continuous Fan)
b. Cooling airflow --- BLACK (enabled when the Y terminal is energized)
ADJUST THE BLOWER SPEED TAPS AS NECESSARY FOR THE PROPER AIR TEMPERATURE RISE FOR EACH INSTALLATION.
3. Airflows over 1800 CFM require bottom return, two ---side return, or bottom and side return. A minimum filter size of 20” x 25” (508 x 635 mm) is required.
4. For upflow applications, air entering from one side into both the side of the furnace and a return air base counts as a side and bottom return.
5. Highlighted areas indicate that this airflow range is beyond the range allowed for heating. THESE AIRFLOW RANGES MAY ONLY BE USED FOR COOLING.

Venting System Length Calculations
The Total Equivalent Vent Length (TEVL) for EACH combustion air or vent pipe equals the length of the venting system, plus the equivalent
length of elbows used in the venting system from Table 2.
Standard vent terminations or factory accessory concentric vent terminations count for zero deduction.
See vent system manufacturer’s data for equivalent lengths of flexible vent pipe or other termination systems. DO NOT ASSUME that one
foot of flexible vent pipe equals one foot of straight PVC/ABS DWV vent pipe.
Compare the Total Equivalent Vent Length to the Maximum Equivalent Vent Lengths in Tables 1 and 3.
Example 1
59SC2A
A direct--vent 60,000 Btuh furnace installed at 2100 ft. (640 M). Venting system includes, FOR EACH PIPE, 100 feet (30 M) of vent pipe,
95 feet (28 M) of combustion air inlet pipe, (3) 90_ long radius elbows, (2) 45_ long radius elbows and a factory accessory concentric vent
kit.
Can this application use 2--in. (50 mm ND) PVC/ABS DWV vent piping?
Measure the required linear length of air inlet and vent pipe; insert the
longest of the two here:
Add equiv length of (3) 90º long-radius elbows
(use the highest number of elbows for either the
3

3 ft
vent or inlet pipe)
Add equiv length of (2) 45º long-radius elbows
(use the highest number of elbows for either the
2

Example 2
A direct--vent 60,000 Btuh furnace installed at 2100 ft. (640 M) Venting system includes, FOR EACH PIPE, 100 feet (30 M) of vent pipe,
95 feet (28 M) of combustion air inlet pipe, (3) 90_ long radius elbows, and a polypropylene concentric vent kit. Also includes 20 feet (6 M)
of flexible polypropylene vent pipe, included within the 100 feet (30 M) of vent pipe.
Assume that one meter of flexible 60 mm or 80 mm polypropylene pipe equals 2 Meters of PVC/ABS pipe. VERIFY FROM VENT
MANUFACTURER’S INSTRUCTIONS.
Can this application use 60 mm (O.D.) polypropylene vent piping? If not what size piping can be used?
Measure the required linear length of air inlet and vent pipe; insert the
longest of the two here:
Add equiv length of (3) 90º long-radius elbows
(use the highest number of elbows for either the

NOTES:
1. Use only the vent pipe sizes shown for each furnace. It is NOT necessary to choose the smallest diameter pipe possible for venting.
2. NA --- Not allowed. Pressure switch will not close, or flame disturbance may result.
3. Total equivalent vent lengths under 10’ for 40,000 BTUH furnaces from 0 to 2000 ft. (0 to 610 M) above sea level require use of an outlet choke plate .
Failure to use an outlet choke when required may result in flame disturbance or flame sense lockout.
4. Not all furnace families include 140,000 BTUH input models.
5. Vent sizing for Canadian installations over 4500 ft (1370 M) above sea level are subject to acceptance by local authorities having jurisdiction.
6. Size both the combustion air and vent pipe independently, then use the larger size for both pipes.
7. Assume the two 45_ elbows equal one 90_ elbow. Wide radius elbows are desirable and may be required in some cases.
8. Elbow and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.
9. The minimum pipe length is 5 ft. (1.5 M) linear feet (meters) for all applications.
10. Use 3 ---in. (76 mm) diameter vent termination kit for installations requiring 4 ---in. (102 mm) diameter pipe.

RETURN AIR TEMPERATURE
This furnace is designed for continuous return--air minimum temperature of 60_F (15_C) db or intermittent operation down to 55_F (13_C)
db such as when used with a night setback thermometer. Return--air temperature must not exceed 80_F (27_C) db. Failure to follow these
return air limits may affect reliability of heat exchangers, motors and controls.

Concentric Vent Kit
Downflow Subbase
A93086
A88202
A concentric vent kit allows vent and combustion--air pipes to
terminate through a single exit in a roof or side wall. One pipe
runs inside the other allowing venting through the inner pipe and
combustion air to be drawn in through the outer pipe.
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
CSA design certified for use with Carrier branded furnaces when
installed in downflow applications.
