The boiler features a quick-open top and a swing-away burner door that provides full combustion chamber access, making inspection, cleaning, and servicing significantly faster.

The boiler includes a low water cutoff and full water trim as standard equipment. Supply and return pipe connections are both 1.5 inches, and the unit runs on 120V single-phase power. It is ASME certified, CSA certified, and UL listed. The Slate Gray cabinet finish, introduced in 2021, gives the unit a clean, professional appearance. This boiler is Energy Star Qualified when ordered with the optional vent damper kit.
