The 59SC5 Multipoise Comfort Series Condensing Gas Furnace features energy efficiency up to 96.0% AFUE gas efficiency and workhorse PSC blower motor. This gas furnace also features 4-way multipoise installation flexibility, and is available in eleven model sizes. 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. Low NOx units are designed for California installations and meet 40 ng/J NOx emissions. Can be installed in air quality management districts with a 40 ng/J NOx emissions requirement. Units are design certified in Canada, and are certified for mobile/manufactured home use.

STANDARD FEATURES

• Aluminized-steel primary heat exchanger.
• Stainless-steel condensing secondary heat exchanger.
• High-quality corrosion-resistant prepainted steel cabinet with hemmed edges for safety.
• Factory-configured ready for upflow applications.
• Direct-vent/sealed combustion, single-pipe venting or ventilated combustion air.
• PSC blower motor, single-speed inducer motor, and single-stage gas valve.
• Self-diagnostics with SuperBrite LED.
• Approved for Twinning applications (060-10 through 120-20 sizes, only).
• Propane convertible.
• Approved for Manufactured Housing/Mobile Home applications (except 26,000 and 140,000 Btuh input) with MH accessory kit.
• Convenient Air Purifier and Humidifier electrical connections.
• Residential installations may be eligible for consumer financing through the Retail Credit Program.
• Cabinet air leakage less than 2.0% at 1.0 in. W.C. and cabinet air leakage less than 1.4% at 0.5 in. W.C. when tested in accordance with ASHRAE standard 193.

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 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 - 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. 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 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.
