FEATURES AND BENEFITS
HYBRID HEAT® 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
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 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 gas furnace
reliability and continues Carrier’s tradition of technology leadership and
innovation in providing a reliable and durable product.
Comfort™ ECM Blower Motor - This basic ECM, or electronically
commutated motor, can provide an efficiency enhancement for select
Carrier air conditioner or heat pump systems. It uses less electrical
power than its PSC counterpart and has 5 speeds.
Reliable Heat Exchanger Design - The aluminized steel, clam shell
primary heat exchanger has 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.
Media Filter Cabinet - Enhanced indoor air quality in the home is made
easier with our media filter cabinet-accessory (purchased separately).
When installed as a part of the system, this cabinet allows for easy and
convenient addition of a Carrier high efficiency air filter.
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.
Direct or Single-pipe Venting, or Optional Ventilated Combustion
Air - All sizes except the 26,000 BTUH model can be vented for direct
vent/two-pipe, ventilated combustion air, or single-pipe applications.
The 26,000 BTUH model can use the same 2-pipe venting system using
outside air for combustion, but is not considered direct-vent.
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 burners.
Insulated Casing - Foil-faced insulation in the heat exchanger section of
the casing minimizes heat loss.
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 a quality management system registered to ISO 9001.

SPECIFICATIONS
The furnace should be sized to provide 100 percent of the design heating load requirement plus any margin that occurs because of furnace model size
capacity increments. None of the furnace model sizes can be used if the heating load is 12,000 BTUH or lower. Use Air Conditioning Contractors of
America (Manual J and S); American Society of Heating, Refrigerating, and Air-Conditioning Engineers; or other approved engineering method to
calculate heating load estimates and select the furnace. Excessive oversizing of the furnace may cause the furnace and/or vent to fail prematurely,
customer discomfort and/or vent freezing.
Failure to follow these guidelines is considered faulty installation and/or misapplication of the furnace; and resulting failure, damage, or repairs may
impact warranty coverage.

Air Delivery - CFM (Bottom Return With Filter)
NOTE:
1. A filter is required for each return-air inlet. Airflow performance includes a 3/4-in. (19 mm) washable filter media (see accessory list). To determine airflow performance without this
filter, assume an additional 0.1 in. w.c. available external static pressure.
2. ADJUST THE BLOWER SPEED TAPS AS NECESSARY FOR THE PROPER AIR TEMPERATURE RISE FOR EACH INSTALLATION.
3. The “Function” column identifies which speed taps can be used for heating.
4. If the same motor speed tap is needed for heating and cooling, a Jumper Wire accessory kit is available, see Product Data accessories for the current Jumper Wire accessory part number.
Reference the “Start-up, Adjustments, and Safety Check” section of installation instructions for further Jumper Wire instructions.
5. 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.
6. 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.
7. The “-” entry indicates an unstable operating condition.

Deductions from Maximum Equivalent Vent Length - Ft. (M)
NOTE:
1.Use only the smallest diameter pipe possible for venting. Over-sizing may cause flame disturbance or excessive vent terminal icing or freeze-up.
2. NA - Not allowed. Pressure switch will not close, or flame disturbance may result.
3. Vent sizing for Canadian installations over 4500 ft (1370 M) above sea level are subject to acceptance by local authorities having jurisdiction.
4. Size both the combustion air and vent pipe independently, then use the larger size for both pipes.
5. Assume the two 45_ elbows equal one 90_ elbow. Wide radius elbows are desirable and may be required in some cases.
6. Elbow and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.
7. The minimum pipe length is 5 ft. (2 M) linear feet (meters) for all applications.
8. Use 3-in. (76 mm) diameter vent termination kit for installations requiring 4-in. (102 mm) diameter pipe

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 Deductions from Maximum Equivalent Vent Length - Ft. (M) Table.
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 Maximum Equivalent Vent Length Table.
Example 1
A direct-vent 60,000 BTUH furnace installed at 2100 ft. (640M). Venting system includes FOR EACH PIPE:
70 feet (22 M) of vent pipe, 65 feet (20 M) of combustion air inlet pipe, (3) 90º long-radius elbows, (2) 45º long-radius elbows, and a factory accessory
concentric vent kit.
Can this application use 2” (50 mm ND) PVC/ABS DWV vent piping?
Example 2
A direct-vent 60,000 BTUH furnace installed at 2100 ft. (640M). Venting system includes FOR EACH PIPE:
100 feet (30 M) of vent pipe, 95 feet (29 M) of combustion air inlet pipe, (3) 90º long-radius elbows, and a polypropylene concentric vent kit. Also
includes 20 feet (6.1 M) of flexible polypropylene vent pipe, included within the 100 feet (30 M) of vent pipe.
VERIFY FROM POLYPROPYLENE VENT MANUFACTURER’S INSTRUCTIONS for the multiplier correction for flexible vent pipe.
Can this application use 60mm o.d. (2”) 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 70 ft. (22 M)
Use length of the longer of the vent
or air inlet piping system
