Laars’ wall-mounted, modulating-condensing Mascot II boiler offers high efficiency, ease of use and versatility in a small, 100-pound package. The low NOx, 95% AFUE, sealed-combustion, fully modulating system is available as a 128 mbh-input boiler or combination boiler and water heater. Both are Energy Star-qualified. The boiler comes with a built-in condensate trap and an auto air-elimination vent. Concentric or two-pipe venting permits the use of standard PVC or CPVC piping (up to 100 feet with 3-inch pipe).
