The Evolution® 987M A unit with an AFUE of up to 97 percent is available in a new high-efficiency line of gas furnaces. The fully modulating gas furnace has load matching performance. A modulating gas valve is capable of adjusting from 40 to 100 percent of capacity, enabling lower speeds over longer periods of time for optimum energy efficiency. The unit is managed by the Evolution control, which helps homeowners optimize their comfort by improving zoning capabilities while lowering operating costs. In addition, the furnace is built with variable-speed ECM (electronically commutated motor) inducer and blower motors that aid in quieter operation and customized comfort, the company says. The line contains four models of the Evolution 987M modulating furnace and includes the two-stage Evolution 986T and Preferred™ Series units, as well as single-stage Preferred Series units. Outputs range from 40,000 to 120,000 Btuh. The units are 35 inches tall and some models are as narrow as 14.2 inches wide, and they are designed to fit smaller spaces. The entire gas furnace line offers four-way multipoise units with a rotating elbow to allow venting flexibility for faster installation in upflow, downflow, or horizontal applications. The units offer an easy-access condensate trap; a front-facing igniter attachment; two-door access with quarter-turn knobs; and a longer, rail-mounted pullout blower.
