Ruud R951V0855A21M4SCAP Gas Furnace 85000 Btu 95% Afue

Product Description

The RUUD R951V0855A21M4SCAP is a single-stage, multi-position residential gas furnace rated at 85,000 BTU/h with 95% AFUE efficiency. It uses a variable speed ECM blower motor to deliver consistent airflow, tighter humidity control, and quieter operation compared to fixed-speed units. The furnace ships with EcoNet Bluetooth connectivity built in, allowing licensed HVAC technicians to commission, monitor, and troubleshoot the unit directly from the Ruud Contractor App without configuring DIP switches. Direct Spark Ignition (DSI) handles ignition duties, and a patented block drain sensor automatically shuts down the unit and triggers a diagnostic code when the condensate drain is obstructed.

This furnace is designed for residential installations where a high-efficiency, multi-position unit is required. Multi-position capability allows installation in upflow, downflow, or horizontal orientations, making it adaptable to attic, closet, basement, and crawlspace applications. The 21-inch cabinet width fits standard air handler closet openings. The unit is rated for natural gas fuel and is sized for up to 5 nominal tons of matched cooling capacity, making it suitable for whole-home systems paired with a compatible cooling coil and condensing unit.
