This Carrier furnace offers apatented algorithm that continually monitors and adjusts furnaceoperation by looking at both current and past conditions todetermine the most effective stage of heating and the amount oftime to run each stage, every cycle.SmartEvapt Technology — When paired with a compatiblethermostat, this dehumidification feature overrides the coolingblower off-delay when there is a call for dehumidification. Bydeactivating the blower off-delay, SmartEvap technology preventscondensate that remains on the coil after a dehumidification cyclefrom re-humidifying throughout the home. This results in reducedhumidity and a more comfortable indoor environment for thehomeowner.Unlike competitive systems, SmartEvap technology only overridesthe cooling blower off delay when humidity control is needed.Once humidity is back in control, SmartEvap re-enables theenergy-saving cooling blower off-delay.ComfortFant Technology — Sometimes the constant fan settingon a standard furnace system can actually reduce homeownercomfort by providing too much or too little air! Fan On Plustechnology improves comfort all year long by allowing thehomeowner to select the continuous fan speed of their choice usinga compatible thermostat.HYBRID HEATR Dual Fuel system — This system can providemore control over your monthly energy bills by automaticallyselecting the most economical method of heating. With HYBRIDHEAT, our system automatically switches between the gas furnaceand the electric heat pump as outside temperatures change tomaintain greater efficiency and comfort than with any traditionalsingle-source heating system. The heat pump also delivershigh-efficiency cooling in the summer.Power Heatt Igniter — Carrier’s unique SiN igniter is not onlyphysically robust but it is also electrically robust. It is capable ofrunning at line voltage and does not require complex voltageregulators as do other brands. This unique feature further enhancesthe gas furnace reliability and continues Carrier’s tradition oftechnology leadership and innovation in providing a reliable anddurable product.Full-Featured, Variable Speed Motors — Our variable--speedECM (Electronically Commutated Motor) optimizes comfort levelsin the home year round; features such as passive/activedehumidification, ramping profiles, and quiet operation. They canprovide cooling match enhancements to increase the effectiveSEER of select Carrier air conditioner or heat pump system. Thismotor does not report back RPM and static pressure to enable staticpressure reporting to the UI or zoning system, which is required forzoning, active filter monitoring and system static pressurereporting.Reliable Heat Exchanger Design — The aluminized steel, clamshell primary heat exchanger was re--engineered to achieve greaterefficiency out of a smaller size. The first two passes of the heatexchanger are based on the current 80% product, a design withmore 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 essentialcomponent.The condensing heat exchanger, a stainless steel fin and tubedesign, is positioned in the furnace to extract additional heat.Stainless steel coupling box componentry between heat exchangershas exceptional corrosion resistance in both natural gas andpropane applications.Optional Media Filter Cabinet — Enhanced indoor air quality inthe home is made easier with our media filter cabinet Wheninstalled as a part of the system, this cabinet allows for easy andconvenient 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 modelswhen one unit will do it all. The new heat exchanger design allowsthese units to achieve the certified AFUE in all positions.Direct or Single-pipe Venting, or Optional VentilatedCombustion Air — This furnace can be installed as a 2-pipe(Direct Vent) furnace, in an optional ventilated combustion airapplication, or in single-pipe, non-direct vent applications. Thisprovides added flexibility to meet diverse installation needs.Sealed Combustion System — This furnace brings in combustionair from outside the furnace, which results in especially quietoperation. By sealing the entire combustion vestibule, the entirefurnace can be made quieter, not just the burners.Insulated Casing — Foil-faced insulation in heat exchangersection of the casing minimizes heat loss. The acoustical insulationin the blower compartment reduces air and motor noise for quietoperation.Monoport Burners — The burners are specially designed andfinely tuned for smooth, quiet combustion and economicaloperation.Bottom Closure — Factory--installed for side return; easilyremovable for bottom return. The multi-use bottom closure canalso serve for roll-out protection in horizontal applications, and actas the bottom closure for the optional return air base accessory.Certifications — This furnace is CSA (AGA and CGA) designcertified for use with natural and propane gases. The furnace isfactory--shipped for use with natural gas. A CSA listed gasconversion kit is required to convert furnace for use with propanegas. The efficiency is AHRI efficiency rating certified. This furnacemeets California Air Quality Management District emissionrequirements.2

Maximum cooling airflow is achieved when switches SW2 ---6, SW2 ---7, SW2 ---8 and SW1 ---5 are set to ON, and SW2 ---2 is set to OFF.3. All heating CFM’s are when low heat rise adjustment switch (SW1 ---3) and comfort/efficiency adjustment switch (SW1 ---4) are both set to OFF.4. Ductwork must be sized for high ---heating CFM within the operational range of ESP. Operation within the blank areas of the chart is not recommendedbecause high ---heat operation will be above 1.0 ESP.5. All airflows of 1880 CFM or less on 21” and 24.5” casing size furnaces are 5% less on side return only installations.6. Return air above 1800 CFM on 24.5” casing requires two sides, one side and bottom, or bottom only to allow sufficient airflow to the furnace.7. 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.8. Airflow not stable at this ESP.8

Venting System Length CalculationsThe Total Equivalent Vent Length (TEVL) for EACH combustion air or vent pipe equals the length of the venting system, plus the equivalentlength 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 onefoot 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 159TP6AA direct--vent 60,000 Btuh furnace installed at 2100 ft.
