Detailed specifications for each model, including specific outputs, blower sizes, and filter requirements, are available in the full product documentation.

Dimensions and Clearances

The furnaces are available in various cabinet widths, from 14" up to 24½" for the AR9T96 series and 17½" to 21" for the AD9T96 series. Detailed diagrams illustrate unit dimensions, connection points (gas, electrical, vent, drain), and air intake/discharge locations for different installation positions (upflow, horizontal, downflow). Minimum clearances to combustible materials are specified for sides, rear, front, bottom, flue, and top, which vary based on the installation position.

Airflow Specifications

The document includes comprehensive tables detailing airflow performance (CFM) at various external static pressures for both heating and cooling operations across different thermostat tap settings and models. These tables are crucial for proper system balancing and performance tuning.

Temperature Rise Chart

A chart is provided to illustrate the relationship between BTU output and temperature rise for different airflow rates (CFM). It includes key formulas for calculating performance: BTU/h Output = CFM x 1.08 x Rise, and Rise = BTU/h Output / (CFM x 1.08).

Wiring Diagram

A detailed wiring diagram is included, illustrating the electrical connections for the furnace. It maps out the integration of components such as the hot surface igniter, two-stage gas valve, pressure switches (high and low fire), flame sensor, limit controls, induced draft blower, circulator blower, and the integrated control module. The diagram also provides essential notes on safety precautions, recommended replacement parts, grounding requirements, and error code status displays via a seven-segment display.

Available Accessories

A range of accessories are available to enhance installation and functionality, including:

• Vent Kits (Concentric, Flush Mount)
• Drain Kits
• External Filter Racks
• Fossil Fuel (Dual Fuel) Kits
• High-Altitude Kits (Natural Gas and LP Gas)
• Horizontal Drain Tubing Kits
• Low LP Gas Pressure Switches
• LP Conversion Kits
• Downflow Sub-Bases
