As of February 2015, manuals for Dunkirk boilers are available on the manufacturer's website, Dunkirk.com. Manuals are available for various fuel types and models of boilers.
Manuals can be found under the "Products" link on the main page of the Dunkirk website. A "Looking for Downloads?" box is available from the "Products" link. Under the list of different types of boilers, there is a list of links to available manuals. There is also a search box to help find a manual for a specific boiler model.
In most instances, manuals can only be viewed or downloaded using Adobe Acrobat. If a manual is not listed, customers can search archived materials or download the Dunkirk Literature Request Form.
