FEATURES AND BENEFITS
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
925SA
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 blower off delay. when humidity control is needed.
Once humidity is back in control, SmartEvap re-enables the
energy-saving cooling blower off-delay.
FanOnPlust 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.
HYBRID HEATR 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, our system automatically switches between the gas furnace
and the 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.
Boost ECM Blower Motor — This basic ECM, or electronically
commutated motor, can provide an efficiency enhancement for
select Bryant air conditioner or heat pump systems. It uses less
electrical power than its PSC counterpart and also has a wider
range of speeds
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 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.
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.

Venting System Length Calculations
The maximum length for each vent pipe (inlet or exhaust) equals the Maximum Equivalent Vent Length (MEVL) from Table 1 or Table 3
minus the number of elbows multiplied by the deduction for each elbow in Table 2.
Standard vent terminations and concentric vent terminations count for zero deductions.
See Vent Manufacturers’ data for equivalent lengths of flexible vent piping.
925SA
DO NOT ASSUME that one foot of flexible vent pipe is equivalent to one foot of standard PVC vent pipe.
Example
A direct--vent 60,000 Btuh furnace installed at 2100 ft. (640 M) with 2--in.(51 mm) vent piping. Venting system includes, FOR EACH
PIPE, (3) 90_ long radius elbows, (2) 45_ long radius elbows and a concentric vent kit.

4501 to 10,000 Ft. (0 to 1370 M) Altitude
NOTE: Maximum Equivalent Vent Length (MEVL) includes standard and concentric vent termination and does NOT include elbows.
Use Table 2 - Deductions from Maximum Equivalent Vent Length to determine allowable vent length for each application.
1. Use only the vent pipe sizes shown for each furnace. It is NOT necessary to choose the smallest diameter pipe possible for venting.
2. NA --- Not allowed. Pressure switch will not close, or flame disturbance may result.
3. Total equivalent vent lengths un der 10’ for 40,000 BTUH furnaces from 0 to 2000 ft. (0 to 610 M) above sea level require use of a n outlet choke plate .
Failure to use an outlet choke when required may result in flame disturbance or flame sense lockout.
4. Not all furnace fa milies include 140,000 BTUH input models.
5. Vent sizing for Cana dian installations over 4500 ft (1370 M) above sea level are subject to acceptance by l ocal authorities having ju risdiction.
6. Size both the combustion air and vent pipe independently, then use the larger size for both pipes.
7. Assume the two 45_ elbows equal one 90_ elbow. Wide radius elbows are desirable and may be required in some cases.
8. Elbow and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.
9. The minimu m pipe length is 5 ft. (1.5 M) linear feet (meters) for all application s.
10. Use 3 - --in . (76 mm) diameter vent termination kit for installations requiring 4--- in. (102 mm) diameter pipe.
This furnace is designed for continuous return--air minimum temperature of 60_F(15_C) db or intermittent operation down to 55_F(13_C)
db such as when used with a night setback thermometer. Return--air temperature must not exceed 80_F(27_C) db. Failure to follow these
return air limits may affect reliability of heat exchangers, motors and controls.
