The Series GM cast iron, hot water boiler is ideal for use in large residences or commercial applications. This natural gas, atmospheric boiler is designed for use with a conventional chimney for simple installations.
Available in four sizes, the Series GM boiler features front mounted controls in the boiler vestibule for safe operation and easy servicing. Boilers are available with 30, 50, 80 or 100 psi safety relief valves, and are packaged and designed with the return piping located in the front and the supply piping at the top/front of the boiler. These features provide installation flexibility and allow the Series GM boiler to be used for any single, modular, or multiple boiler job.
A vertical draft hood and deluxe insulated enameled steel jacket are standard on all Series GM boilers. Five and six- section boilers feature a standard vent damper (optional on seven and eight-section boilers). Steel push nipples on all boilers assure a water-tight seal between sections for a lifetime of dependability.
All Series GM boilers are available with standard intermittent ignition provided by the Honeywell SmartValve® System. This system provides the safety and ignition functions in one device for simple, dependable operation. Five and six-section boilers are also available with optional standing pilot ignition. The Series GM five and six-section boilers exceed the federal standards for residential AFUE and the seven and eight-section boilers meet the ASHRAE 90.1 efficiency minimum as required by federal standards for commercial boilers.
