The Series GM cast iron, hot water boiler is for both commercial and residential applications. This natural gas, atmospheric boiler is designed for use with a conventional chimney for simple installation, says the company. Available in four sizes, the boiler features front-mounted controls in the boiler vestibule for safe operation and easy servicing, the company says. Boilers are available with 30-, 50-, 80-, or 100-psi safety relief valves. Standard equipment includes an insulated, enameled steel jacket that reduces boiler heat loss, says the manufacturer.
