FEATURES AND BENEFITS

Perfect HeatR Technology — This feature with Adaptive Control

is a proprietary function that promotes homeowner comfort through two stages of heating. This Bryant furnace offers a

986TA

patented algorithm that continually monitors and adjusts furnace operation by looking at both current and past conditions to determine the most effective stage of heating and the amount of time to run each stage, every cycle.

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 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.

(Electronically Commutated Motor) provides variable-speed operation to optimize comfort levels in the home year round; features such as passive/active dehumidification, ramping profiles, and quiet operation. They can provide cooling match enhancements to increase the effective SEER of select Bryant air conditioner or heat pump system. This motor does not report back RPM and static pressure to enable static pressure reporting to the UI or zoning system, which is required for zoning, active filter monitoring and system static pressure reporting.

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.

1. Nominal 350 CFM/ton cooling airflow is deliver ed with SW1-5 and SW4-3 set to OFF. Set both SW1-5 and SW4-3 to ON for +7% airflow (nominal 370 CFM/ton). Set SW1-5 to ON and SW4-3 to OFF for +15% airflow (nominal 400 CFM/ton). Set SW4-3 to ON and SW1-5 to OFF for -7% airflow (nominal 325 CFM/ton).

The above adjustments in airflow are subject to motor horsepower range/capacity.

2. Maximum cooling airflow is achieved when switches SW2-1, SW2-2, S W2-3 and SW1-5 are set to ON, and SW4-3 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 E.S.P. Operation within the blank areas of the chart is not recommended

because high-heat operation will be above 1.0 E.S.P.

5. All airflows of 1800 CFM or less on 21” and 24.5” casing size furnaces are 5% less on side return only installations.

6. Airflows over 1800 CFM require bottom return, two-side return, or bottom and side return. A minimum filter size of 20” x 25” is required.

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 E.S.P.

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. 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.

Maximum Equivalent Vent Length = 127 ft. (From Table 1)

Deduct (3) 90 long radius 3 x 3 ft. = - 9 ft. (From Table 2) Deduct (2) 45 long radius 2 x 1.5 ft. = - 3 ft. (From Table 2) No deduction for Concentric Vent Kit 0 ft. = - 0 ft. (From Table 2)

Maximum Vent Length = 115 ft. For EACH vent or inlet pipe

NOTES:

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 cl ose, or flame disturbance may result.

3. Total equivalent vent lengths un der 10’ for 40,000 BTUH furn a ces from 0 to 2000 ft. (0 to 610 M) above sea level require use of an outlet choke plate .

Failure to use an outlet choke when required may result in flame disturbance or flame sense lockout.

4. Not all furnace families include 140,000 BTUH input models.

5. Vent sizing for Canadian installations over 4500 ft (1370 M) above sea level are subject to acceptance by local authorities having jurisdiction.

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 minimum pipe length is 5 ft. (1.5 M) lin ear feet (meters) for all applications.

10. Use 3 ---in. (76 mm) diameter vent termination kit for installation s requiring 4 --- in. (102 mm) diameter pipe.
