The Plus 80™ Model 311 Multi-Poise Unit Profile The Right Fit For Comfort and Value. When winter arrives, most of us retreat to our homes for comfort. After all, there’s nothing quite like enjoying the warmth of your home when chilling winds and falling temperatures are waiting outside. And, there’s nothing quite like the reliability and value provided by the Bryant Plus 80 gas furnace. The Plus 80 delivers proven heating performance in a versatile and compact design that fits even the most challenging installations. Once it’s installed, you’ll enjoy energy-efficient operation from one of the quietest standard 80% AFUE (Annual Fuel Utilization Efficiency) furnaces available. Best of all, you’ll enjoy knowing that the Plus 80 offers exceptional reliability backed by Bryant’s commitment to your satisfaction. Features Quiet Operation & Comfort Every Season. The Plus 80 has always been a great value in heating comfort, and now it’s even better thanks to some significant design changes. For example, we’ve made this model extra quiet by reducing noise from the burner, the inducer and the fan. For improved comfort during unusually large get togethers or changing weather conditions, Bryant offers the new Fan On Plus™ feature. Fan On Plus improves comfort all year long by allowing you to select different fan speeds during continuous fan operation to achieve more or less airflow as needed. For additional comfort during the cooling season, add our optional Thermidistat™ Control. This enables a feature called SmartEvap™, which allows your system to reduce summertime humidity levels by nearly 10% over standard systems. The Plus 80 can be the cornerstone of a complete, year-round comfort system. A Fitting Design. Bryant understands that all homes offer unique challenges, especially where installation is concerned. The Plus 80 was designed with those challenges in mind. It’s several inches shorter than older models, thanks to a patented heat exchanger. And, it’s designed to install in all four standard positions with thirteen possible venting setups. That means no matter where you live and what style of home you own, the Plus 80 can be the perfect fit.
