sizes, only)

S Propane convertible (see accessory list). S Approved for Manufactured Housing/Mobile Home applications

with MH accessory kit.

S Convenient Air Purifier and Humidifier connections. S Residential installations may be eligible for consumer financing

through the Retail Credit program.

S Certified to leak 2% or less of nominal air conditioning CFM

delivered when pressurized to 1--in. water column with all present air inlets, air outlets, and condensate drain port(s) sealed.

LIMITED WARRANTY*

S 10 year parts and 20 year heat exchanger limited warranty to the

original purchaser upon timely registration.

S Limited warranty period is five years for parts and twenty years

for the heat exchanger if not registered within 90 days of installation.{

* For owner occupied, residential applications.

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

59SC2A

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, clamshell 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 GAMA 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 an d side r etu rn. 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 r an ge all owed for h eating. THESE AIRFLOW RANGES MAY ONLY BE USED FOR COOL-

ING.

Venting System Length Calculations

The maximum length for each vent pipe (inlet or exhaust) equals the Maximum Equivalent Vent Length (MEVL) from Table 1 or Table 3 minus the number of elbows multiplied by the deduction for each elbow in Table 2.

Standard vent terminations and concentric vent terminations count for zero deductions. See Vent Manufacturers’ data for equivalent lengths of flexible vent piping. DO NOT ASSUME that one foot of flexible vent pipe is equivalent to one foot of standard PVC vent pipe.

59SC2A

Example

A direct--vent 60,000 Btuh furnace installed at 2100 ft. (640 M) with 2--in.(51 mm) vent piping. Venting system includes, FOR EACH PIPE, (3) 90_ long radius elbows, (2) 45_ long radius elbows and a concentric vent kit.

Maximum Equivalent Vent Length = 127 ft. (From Table 1)

Deduct (3) 90 long radius 3 x 3 ft. = - 9 ft. (From Table 2) Deduct (2) 45 long radius 2 x 1.5 ft. = - 3 ft. (From Table 2) No deduction for Concentric Vent Kit 0 ft. = - 0 ft. (From Table 2)

Maximum Vent Length = 115 ft. For EACH vent or inlet pipe

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 u se o f 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 f o r Canadian installations over 4500 ft (1370 M) above sea l evel 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 min imum 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 in stall ations requ iring 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

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.

Downflow Subbase

A88202

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.
