The Mascot II wall-mounted, modulating condensing boiler offers high efficiency, ease of use, and versatility in a small, 100-pound package. The low NOx, 95 percent AFUE, sealed-combustion, fully modulating system is available as a 125 MBtuh input boiler or combination boiler and water heater; both are Energy Star qualified. The boiler is designed for ease of installation and serviceability, with built-in condensate trap and auto air-elimination vent. Setup is easier with full access to both the gas valve and control panel at the same time, states the company. Also included is a sealed condensate trap that does not need to be primed at startup. The Mascot II offers zero-clearance installation, allowing the unit to be installed in tight spaces, and the option of multiple boiler staging to handle larger-sized heating loads, and common venting. Concentric or two-pipe venting permits the use of standard PVC or CPVC piping up to 100 feet with 3-inch pipe.
