The Weil-McLain Ultra boiler is available in six sizes and offers top efficiency with an LCD display. As a condensing boiler, it should be configured with primary/secondary piping. Easy-Up Manifolds for Ultra boilers work with the circulator that is included with the boiler to create such piping. They come with dielectric unions, shut-off valves, a check valve, a safety relief valve, and optional connections to indirect water heaters. The Easy-Up saves time and effort, making any job look professional.
