Friedrich FR802V1005A21UHSCAP Gas Furnace 100000 Btu 80 Afue

Product Description

The FRIEDRICH FR802V1005A21UHSCAP is a natural gas furnace rated at 80 percent AFUE efficiency and 100,000 BTU/h output. It uses a 2-stage gas valve paired with an ECM variable-speed blower motor, which allows the unit to ramp heating output and airflow to match the load rather than running at full capacity on every cycle. The cabinet is 21 inches wide and supports upflow and horizontal airflow configurations. Licensed HVAC technicians install and commission this furnace in residential and light-commercial applications.

This furnace is suited for upflow or horizontal installations in residential forced-air heating systems, typically paired with a 5-ton cooling coil for year-round HVAC service. The 2-stage operation reduces temperature swings and lowers fuel consumption compared to single-stage equipment. The ECM motor also delivers efficiency gains on the blower side, contributing to lower operating costs across the heating season. A 21-inch cabinet width fits standard closet and utility-room rough openings common in residential new construction and retrofit work.

Key Features

• 80 percent AFUE natural gas furnace with 100,000 BTU/h heating capacity
• 2-stage gas valve reduces short-cycling and improves comfort during mild weather
• ECM variable-speed blower motor lowers electrical consumption and reduces noise
• Upflow and horizontal airflow configurations in a single cabinet
• 21-inch cabinet width fits standard residential utility and closet installations
• Nominal 5-ton airflow rating matches common residential cooling coil sizes

Compatibility

Designed as an OEM-style replacement or new-installation gas furnace for residential forced-air systems requiring an 80 percent AFUE, 2-stage, ECM variable-speed upflow or horizontal unit with a 21-inch cabinet width and 5-ton nominal airflow capacity.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with the International Fuel Gas Code (IFGC), local mechanical codes, and the manufacturer installation instructions. Shut off the gas supply and disconnect electrical power before servicing or replacing any components. Venting must be sized and configured per the appliance venting tables in the IFGC; this is an 80 percent non-condensing furnace and requires Type-B vent or single-wall metal vent where permitted. Low-voltage thermostat wiring connections should be verified against the unit wiring diagram before restoring power.
