FEATURES AND BENEFITS
HYBRID HEATR Dual Fuel system — This system can provide
912SC
more control over your monthly energy bills by automatically
selecting the most economical method of heating. With HYBRID
HEAT, 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 — Bryant’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 Bryant’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 — 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 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.

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 20,000 BTU 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
