Natural or Propane Gas-Fired Boilers by Dunkirk

PLYMOUTH
STEAM II
NATURAL OR PROPANE
GAS-FIRED BOILERS

An ISO 9001-2000 Certified Company
Dunkirk Quality
Since 1928, American-made Dunkirk
Boilers have been leading the industry
in value and reliability with innovative
designs and premium quality
components. Assured performance
has placed Dunkirk quality at the top
in trusted reliability (99.91%*).
Every gas boiler we manufacture is test fired prior
to shipment. This boiler is certified by C.S.A. in the
United States; heat exchangers by ASME; and
efficiency ratings by the Hydronics Institute.
The Plymouth Steam II Boiler by Dunkirk offers
the best combination of heating comfort,
efficiency, reliability... and affordability, making
it one of Americas Hottest Boiler Values.
Heating Efficiency
The high efficiency of the Plymouth steam
boiler renders outstanding performance
and low operating costs.
Electronic Ignition
(Option) Pilot is lit automatically and stays lit
only when needed, eliminating fuel waste.
Integral Draft Diverter
Dunkirk utilizes built-in draft diverter
technology that is factory designed to protect
against harmful carbon monoxide back drafts.
Unlike competitor diverters erected in-field,
Dunkirk eliminates any installation guesswork
to ensure your familys safety.
Effikal Vent Damper
Automatically closes when the unit turns off,
preventing heated air from escaping up the
chimney. Effikal provides the strongest vent
damper warranty in the industry.
Titanium
Burners
Dunkirks exclusive
high-tech titanium
composite burners
resist corrosion and
oxidation while withstanding
more heat
than conventional stainless steel or aluminized
burners. They provide superior strength and
longevity and are backed by a full 3-year warranty,
triple the industry standard.
Cast Iron Sections
& Push Nipples
Dunkirk utilizes cast
iron to construct
the boilers heat
exchanger to provide
heat transfer, reliability
and strength. 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.
Easy Installation
Surprisingly compact, the Plymouth Steam II
Boiler fits in tight spaces and is supplied
assembled, with controls that are accessible
and completely wired. Piping is also at hand
for easy connection to the system.
Easy Maintenance
Low water cutoff is electronic, therefore,
results in minimal homeowner maintenance.
Controls are easily accessible without having
to remove the jacket, and our standard
controls are readily available, making Dunkirk
Boilers easy to service.

The ratings marked Net I=B=R Ratings represent the heat available to
the radiation or terminal units. The Net I=B=R Ratings shown are based
on an allowance of 1.33 in accordance with the factors shown in the
I=B=R Code as published by The Hydronics Institute.
Selection of boiler size should be based upon Net I=B=R Rating being
equal to or greater than the installed radiation in square feet EDR.
Consult manufacturer before selecting a boiler for installations having
unusual piping and pick-up requirements.
These boilers may be installed on combustible flooring when placed
on combustible floor plate.
These gas-fired boilers are sectional cast iron boilers design certified
by C.S.A. in the U.S. for use with natural gas and propane gas. They
are constructed and hydrostatically tested dEngineers) Boiler And Pressure Vessel Code Section IV standards for cast iron
