The contractors’ choice




The PurePro® Advantage gas boiler is a residential, cast-iron, gas-fired water boiler designed for atmospheric draft into a conventional chimney. It is available in heating capacities from 70,000 to 175,000 BTU/hr. and is available for use with natural or LP gas.

The PurePro® Advantage sets the standard for installer-ready gas fired boilers. With its limited lifetime warranty, the Advantage comes standard with intermittent ignition, a Taco 00R 3-speed circulator and Honeywell controls which combine Temperature Limit Control with automatic water temperature adjustment. This user-friendly control is easily accessible, making the Advantage gas boiler simple to install and service. The integral draft diverter provides a low profile design, allowing the boiler to be installed in areas with low clearance.
