MasterTemp™ is a powerful electronic gas heater placed in a space saving enclosure. All four models measure the same cabinet size, ( 21 L x 21W x 28 H ) less vent and water connections. Until you see this heater up close, you won't believe how space saving this heater really is. Heater is power vented and water connections are unionized for easy installation. Controls rotate to 3 positions so there’s no need to reverse the header.

All units are stocked as natural gas heaters. Request conversion kit if propane is required. Quick-change orifice allows easy conversion of gas sources. Propane heaters from the factory are available as a special order item.
DO NOT convert ASME models.
