Near Condensing –

Sealed Combustion,

Multi-Stage Firing

The Dominator® Series offers the ultimate ﬂ exibility in boiler and

water heater application – at a competitive price. Efﬁ ciencies of

over 85% are among the highest available in near condensing

boiler and water heater designs.

The Dominator can operate using room air for combustion or by

drawing outside air directly as a sealed combustion product. Units

can vent combustion gases vertically or horizontally with factory

equipped draft-inducer kits.

The Dominator’s stackable frame option allows units to be stacked

two-high, adding valuable BTU’s while keeping the footprint to the

size of a single unit.

Built-in serviceability features include a slide out heat exchanger

that allows contractors to remove the heat exchanger for service or

repair, without having to disassemble the entire unit.
