With HYBRIDHEAT components, our system automatically switches between thegas furnace and the single--stage electric heat pump as outsidetemperatures change to maintain greater efficiency and comfortthan with any traditional single-source heating system. The heatpump also delivers high-efficiency cooling in the summer.Robust Igniter — Payne’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 Payne’s tradition oftechnology leadership and innovation in providing a reliable anddurable product.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.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 — All sizes except the 26,000 BTUH model canbe vented for direct vent/two-pipe, ventilated combustion air, orsingle-pipe applications. The 26,000 BTUH model can use thesame 2--pipe venting system using outside air for combustion, butis not considered direct--vent. This provides added flexibility tomeet 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.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.Quality Registration — Our furnaces are engineered andmanufactured under an ISO 9001 registered quality system.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

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 below the range allowed for heating. THESE AIRFLOW RANGES MAY ONLY BE USED FOR COOLING.6. All airflows that are shown in BOLD exceed 0.58 watts per CFM at the given external static pressure.7. The “ ---” entry indicates an unstable operating condition.6

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 .
