Friedrich FR801T1005A21UHSNAP 80% Gas Furnace 100K Btu

Product Description

The FRIEDRICH FR801T1005A21UHSNAP is an 80% AFUE single-stage natural gas furnace built for residential and light-commercial forced-air heating systems. Rated at 100,000 BTU input, it delivers consistent heat output through an electronically commutated motor (ECM) blower drive. The 21-inch-wide cabinet is configured for upflow and horizontal installation, making it suitable for a range of mechanical room and attic installations. This unit belongs to the Builders Series line and is typically installed by licensed HVAC contractors on new construction or replacement applications. The ECM motor reduces electrical consumption compared to standard PSC motors while supporting matched 5-ton cooling airflow requirements.

This furnace is designed for upflow and horizontal installations in residential new construction and replacement projects. The 5-ton nominal airflow rating makes it compatible with larger duct systems serving homes with significant cooling and heating loads. Natural gas fuel type suits regions with existing gas service infrastructure. The single-stage burner operation provides straightforward control and reliable ignition sequencing, which simplifies commissioning and service. It fits alcove, basement, utility closet, and attic horizontal configurations where a 21-inch cabinet width is appropriate.

Key Features

• 80% AFUE efficiency rating meets minimum federal standards for gas furnaces
• 100,000 BTU/h input capacity for high-demand residential and light-commercial applications
• ECM blower motor reduces operating amperage and supports variable airflow for matched cooling systems
• Single-stage gas valve simplifies wiring, control board integration, and field service
• Upflow and horizontal configuration expands installation flexibility across multiple equipment placements
• 21-inch cabinet width fits standard alcove and platform installations

Compatibility

Designed as an OEM-style upflow and horizontal gas furnace replacement or new-installation unit for natural gas forced-air systems requiring a 5-ton nominal blower and 100,000 BTU/h input capacity.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with the International Fuel Gas Code (IFGC) and applicable local mechanical codes. Shut off gas supply and disconnect electrical power before servicing or making connections. Venting must comply with applicable B-vent or Category I venting requirements for 80% AFUE non-condensing appliances. Do not alter factory gas train components or bypass pressure switch circuits during startup.
