Ruud U97MV0855A21DHSGAP Gas Furnace 97% Afue 85000 Btu

Product Description

The RUUD U97MV0855A21DHSGAP is a modulating natural gas furnace rated at 97% AFUE and 85,000 BTU/h input capacity. It uses a Direct Spark Ignition (DSI) system and an ECM variable-speed blower motor to deliver consistent heat output while minimizing energy consumption. The modulating heating stage adjusts output from low fire up to 100% capacity based on real-time load demand. A fully insulated blower cabinet reduces operating noise. The integrated 7-Segment LED display provides onboard diagnostics, reducing time spent on service calls. This unit is ENERGY STAR certified and EcoNet enabled for remote monitoring via compatible smart thermostat and app. Licensed HVAC technicians install and commission this furnace.

The U97MV0855A21DHSGAP is designed for residential applications where high-efficiency heating and precise comfort control are priorities. At 21 inches wide, it fits standard multi-position installations in downflow and horizontal configurations, making it suitable for closet, alcove, attic, and crawlspace installs. The multi-position design supports flexible duct layout options. The patented block drain sensor monitors condensate and automatically shuts down the furnace if a drain blockage is detected, then alerts the technician via a diagnostic fault code. Nominal cooling capacity pairing is up to 5 tons. Natural gas is the rated fuel type.
