925TA PREFERREDt SERIES TWO--STAGE 4--WAY MULTIPOISE CONDENSING GAS FURNACE, SERIES A

Product Data

A11264

The 925TA Multipoise SEER Boost Condensing Gas Furnace features the two--stage gas valve. The Perfect HeatR technology two--stage gas valve is at the heart of the comfort provided by this furnace, along with the multi--tap ECM blower motor, and two--speed inducer motor. With an Annual Fuel Utilization Efficiency (AFUE) of 96.2%, the Preferred two--stage gas furnace provides exceptional savings when compared to standard single--stage furnaces. This Preferred Gas Furnace also features 4--way multipoise installation flexibility, and available in five model sizes. The 925TA can be vented for direct vent/two--pipe, ventilated combustion air, or single--pipe applications. A Bryant Preferred™ Control and Preferred or Preferred Air Conditioner or Heat Pump, can be used to form a complete Preferred System. All units meet California Air Quality Management District emission requirements. All sizes are design certified in Canada.

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.

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)

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

*Not all families have these models.

Notes:

1. 3 -- - and 4 --- in. Vent pipe systems r equire long radius elbows.

2. Total equivalent vent lengths under 10’ for 40,000 require the use of an outlet choke plate at altitude 0 to 2,000 ft (0 to 610M).

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

3. Vent sizing f o r Canadian installations over 4500 ft (1370m) above sea level are subject to acceptance by the local authorities having jurisdiction.

4. NA --- Not allowed; pressure switch will not close, or fl ame disturbance may result.

5. Do not use pipe size greater than those specified in table or incomplete combustion, flame disturbance, or flame sense lockout may occur.

6. Size both the combustion--- air and vent pipe independently, then use the larger diameter 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. Elbows 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) for all applications.

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

RETURN AIR TEMPERATURE

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.

Concentric Vent Kit

A concentric vent kit allows vent and combustion--air pipes to terminate through a single exit in a roof or side wall. One pipe runs inside the other allowing venting through the inner pipe and combustion air to be drawn in through the outer pipe.

Downflow Subbase

A88202

One base fits all furnace sizes. The base is designed to be installed between the furnace and a combustible floor when no coil box is used or when a coil box other than a Bryant cased coil is used. It is CSA design certified for use with Bryant branded furnaces when installed in downflow applications.
