FEATURES AND BENEFITS

Fully Modulating Gas Valve — When paired with the
EvolutionR control, this furnace improves comfort by adjusting
heating output in 1% increments from 40% to 100% capacity to
meet the heating needs of the home. Precision begins with a
stepper motor to adjust manifold pressures. Stepper motors are
used in electronic devices, such as computer disc drives, which
require precise mechanical positioning. The precision of the
stepper motor, combined with our unique two-point calibration,
allows the modulating furnace to accurately control and directly
deliver the right amount of gas to the burners every time.
Perfect HumidityR Technology —The Perfect Humidity system
actively controls both temperature and humidity in the home to
provide the best comfort all year long. Other systems depend on
heating or cooling demand to manage the moisture in the air. But,
Perfect Humidity gives the homeowner the right amount of
humidity day and night, even in mild weather. No other
manufacturer can do this! Perfect Humidity saves energy, too. By
keeping humidity under control, the homeowner can set their
thermostat lower to stay comfortable and save energy.
SmartEvapt Technology — When paired with a compatible
thermostat, this dehumidification feature overrides the cooling
blower off-delay when there is a call for dehumidification. By
deactivating the blower off-delay, SmartEvap technology prevents
condensate that remains on the coil after a dehumidification cycle
from re-humidifying throughout the home. This results in reduced
humidity and a more comfortable indoor environment for the
homeowner.
Unlike competitive systems, SmartEvap technology only overrides
the cooling when humidity control is needed. Once humidity is
back in control, SmartEvap re-enables the energy-saving cooling
blower off-delay.
Fan On Plust Technology — Sometimes the constant fan setting
on a standard furnace system can actually reduce homeowner
comfort by providing too much or too little air! Fan On Plus
technology improves comfort all year long by allowing the
homeowner to select the continuous fan speed of their choice using
a compatible thermostat.
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.
Full-Featured, Communicating, Variable Speed Motors — Our
Perfect ECMt (Electronically Commutated Motor) provides
variable-speed operation to optimize comfort levels in the home
year round; features such as passive/active dehumidification,
ramping profiles, constant air flow and quiet operation. They can
provide cooling match enhancements to increase the effective
SEER of select Bryant air conditioner or heat pump system, and
feature the highest efficiency of all indoor fan motors.

Reliable Heat Exchanger Design — The aluminized steel,
clamshell primary heat exchanger was reengineered 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.
Media Filter Cabinet — Enhanced indoor air quality in the home
is made easier with our media filter cabinet—a standard accessory
on all deluxe furnaces. When installed as a part of the system, this
cabinet allows for easy and convenient addition of a Bryant high
efficiency air filter.
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 Venting or Optional Ventilated Combustion Air — This
furnace can be installed as a 2-pipe (Direct Vent) furnace or as an
optional ventilated combustion air application. 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.
Insulated Casing — Foil-faced insulation in heat exchanger
section of the casing minimizes heat loss. The acoustical insulation
in the blower compartment reduces air and motor noise for quiet
operation.
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.
