Dunkirk is one of the most established names in heating. Their reputation has been built over the years by ingenious design and perpetual innovation. The D248-2600S is a modular steam boiler for large applications. The modular design makes it easy to find a D248 that suits your application without worrying about over —or under —sizing. Cast-iron is used for the construction of the heat exchanger sections to create a boiler that is as durable as it is powerful. Installing a large boiler may seem daunting, but Dunkirk has already handled a lot of the heavy lifting. The modular bases of the D248 are assembled before shipment with the gas valves, manifolds, burners, and pilots preinstalled. When it comes to supplying reliable heating for the largest applications, the D248 shines. With a simplified installation process and incredible longevity, this is an exceptional hydronic heating choice.
Heat retention is a cornerstone of efficiency. Dunkirk employs an insulated boiler jacket with the D248 to reduce wasted heat and make your energy dollar go further.
The D248 is designed for quick inspection and maintenance. The boiler's front panels are easily removed to allow access to the boiler controls. The draft hood of the D248 features a cleanout panel, providing a simple way to clean the flueways.
Wiring for the D248 is streamlined through a "plug 'n play" harness and junction box. This harness is color-coded so that connecting the boiler base controls is not just quick, but error proof.
