Overview

The Bryant 926TA Preferred™ Two-Stage 4-Way Multipoise, Variable Speed Condensing Gas Furnace, Series A, is a high-efficiency heating system designed for residential use. It incorporates two-stage heating and a variable-speed ECM blower motor to provide enhanced comfort and energy savings. The furnace is CSA (AGA and CGA) design certified for use with natural and propane gases (a conversion kit is required for propane). It meets ENERGY STAR® Version 4.0 criteria for gas furnaces with an Annual Fuel Utilization Efficiency (AFUE) up to 96.5%, an AMACF electrical rating, and 2% or less cabinet airflow leakage. All units are design certified in Canada and meet California Air Quality Management District emission requirements.

Function Description:

The 926TA furnace operates with a two-stage gas valve and a variable-speed ECM blower motor, along with a two-speed inducer motor. This allows for precise control over heating output and airflow, contributing to consistent indoor temperatures and improved humidity management. The "Perfect Heat®" technology utilizes a patented algorithm to continuously monitor and adjust furnace operation based on current and past conditions, determining the most effective heating stage and run time for each cycle. "SmartEvap™" technology, when paired with a compatible thermostat, overrides the cooling blower off-delay during dehumidification calls, preventing condensate re-humidification from the coil. "FanOn Plus™" technology enables selection of continuous fan speeds with a compatible thermostat. The furnace is designed for 4-way multipoise installation, accommodating upflow, downflow, or horizontal configurations. It supports direct-vent/sealed combustion, single-pipe venting, or ventilated combustion air applications.
