With its high efficiency, a Plymouth Xtreme boiler is an outstanding choice for performance and low operating cost.
Pilot is lit automatically and stays lit only when needed, eliminating fuel waste.
Unlike competitor's diverters erected in-field, Dunkirk eliminates any installation guesswork to ensure your family's safety. The operation and safety controls for the Plymouth Xtreme are located underneath the jacket. Enclosed controls offer an additional level of consumer safety and minimize the possibility of damage during installation and operation. Since like materials expand and contract in the same proportion during heating and cooling, cast iron push nipples and sections produce stronger, more water-tight seals than steel push nipples or rubber gaskets. Servicing controls is simple with our plug-in wire harness.
