FEATURES AND BENEFITS

Perfect HeatR Technology — This feature with Adaptive Control

is a proprietary function that promotes homeowner comfort

926TA

through two stages of heating. This Bryant furnace offers a 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.

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.

Full-Featured, Variable Speed Motors — Our variable--speed ECM (Electronically Commutated Motor) optimizes 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 enablestatic 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, 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.

Optional Media Filter Cabinet — Enhanced indoor air quality in the home is made easier with our media filter cabinet 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.

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.

Venting System Length Calculations

The Total Equivalent Vent Length (TEVL) for EACH combustion air or vent pipe equals the length of the venting system, plus the equivalent length of elbows used in the venting system from Table 2.

Standard vent terminations or factory accessory concentric vent terminations count for zero deduction. See vent system manufacturer’s data for equivalent lengths of flexible vent pipe or other termination systems. DO NOT ASSUME that one

foot of flexible vent pipe equals one foot of straight PVC/ABS DWV vent pipe. Compare the Total Equivalent Vent Length to the Maximum Equivalent Vent Lengths in Tables 1 and 3.

Example 1

A direct--vent 60,000 Btuh furnace installed at 2100 ft. (640 M). Venting system includes, FOR EACH PIPE, 100 feet (30 M) of vent pipe, 95 feet (28 M) of combustion air inlet pipe, (3) 90_ long radius elbows, (2) 45_ long radius elbows and a factory accessory concentric vent kit.

Can this application use 2--in. (50 mm ND) PVC/ABS DWV vent piping?

Measure the required linear length of air inlet and vent pipe; insert the longest of the two here:

Add equiv length of (3) 90º long-radius elbows (use the highest number of elbows for either the vent or inlet pipe)

926TA

Add equiv length of (2) 45º long-radius elbows (use the highest number of elbows for either the vent or inlet pipe)

Add equiv length of vent termination 0ft. From Table 2

Add correction for flexible vent pipe, if any 0ft.

Total Equivalent Vent Length (TEVL) 112 ft. Add all of the above lines

Maximum Equivalent Vent Length (MEVL) 127 ft. For 2” pip e f rom Table 1

Is TEVL less than MEVL? YES Therefore, 2” pipe may be used

3 x 3ft = 9ft. From Table 2

2 x 1.5 ft = 3ft. From Table 2

100 ft

Use length of the longer of the vent

or air inlet piping system

From Vent Manufacturer’s instructions;

zero for PVC/ABS DWV

Example 2

A direct--vent 60,000 Btuh furnace installed at 2100 ft. (640 M) Venting system includes, FOR EACH PIPE, 100 feet (30 M) of vent pipe, 95 feet (28 M) of combustion air inlet pipe, (3) 90_ long radius elbows, and a polypropylene concentric vent kit. Also includes 20 feet (6 M) of flexible polypropylene vent pipe, included within the 100 feet (30 M) of vent pipe.

Assume that one meter of flexible 60 mm or 80 mm polypropylene pipe equals 1.8 meters of PVC/ABS pipe. VERIFY FROM VENT

MANUFACTURER’S INSTRUCTIONS.

Can this application use 60 mm (O.D.) polypropylene vent piping? If not what size piping can be used?

Measure the required linear length of air inlet and vent pipe; insert the longest of the two here:

Add equiv length of (3) 90º long-radius elbows (use the highest number of elbows for either the vent or inlet pipe)

Add equiv length of (2) 45º long-radius elbows (use the highest number of elbows for either the vent or inlet pipe)

Add equiv length of vent termination 9M x 3ft/M = 18 ft. From Vent Manufacturer’s instructions Add correction for flexible vent pipe, if any 1.8 x 20 ft = 36 ft. From Vent Manufacturer’s instructions Total Equivalent Vent Length (TEVL) 163 ft. Add all of the above lines

3 x 3ft = 9ft. From Vent Manufacturer’s instructions

0 x = 0ft. From Vent Manufacturer’s instructions

100 ft

Use length of the longer of the vent

or air inlet piping system

Maximum Equivalent Vent Length (MEVL) 127 ft. For 2” pip e f rom Table 1

Is TEVL less than MEVL? NO

Maximum Equivalent Vent Length (MEVL) 250 ft. For 3” pip e f rom Table 1

Is TEVL less than MEVL? YES Therefore, 80 mm pipe may be used

Therefore, 60mm pipe may NOT be used;

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 close, or flame disturbance may result.

3. Total equivalent vent lengths under 10’ for 40,000 BTUH furnaces from 0 to 2000 ft. (0 to 610 M) above sea level require use o f an outlet choke plate .

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

4. Not a ll 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 minimu m pipe length is 5 ft. (2 M) lin ear feet (meters) for all applications.

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