Series 32

Products > Commercial Boilers > Series 32

The Series 32 is a commercial, cast-iron, gas-fired, hot-water or steam boiler. The Series 32 is designed for use with a conventional chimney. The boiler is equipped with an electronic ignition system and is available for use with natural gas. The Series 32 is available in firing rates from 380 to 2,850 MBH. This boiler has built-in draft hoods for installation under low ceilings, and a choice of control options make the Series 32 the best choice for a wide variety of commercial applications.

Domestic hot water can be provided by an optional tankless coil water heater on water boilers only. The steam boilers are tapped for Mega-Stor or Maxi-Therm indirect water heaters.

The Series 32 has a compact design which uses preassembled and tested base modules. These modules have individual gas trains with a residential style combination gas valve and ignition control for simplicity and redundancy. These base modules are combined to provide the appropriate input.

Heat exchanger sections are shipped unassembled, which makes them easier to handle, get through narrow doorways and assemble.
