925TA
PREFERREDt SERIES TWO- - STAGE
4- -WAY MULTIPOISE
CONDENSING GAS FURNACE, SERIES A
The 925TA Multipoise SEER Boost Condensing Gas Furnace
features two- -stage heating. 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 up to 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 six 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.
STANDARD FEATURES

  • Page 9: Venting System Length Calculations

    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.

    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.
