Installation Instructions; Boiler Ratings And Capacities - Dunkirk XEB-2 Installation, Operation & Maintenance Manual

This boiler cannot be used with all types of chimneys. Read
these instructions carefully before installing.
These Gas-Fired Hot Water Boilers are low pressure, sec-
tional cast iron boilers Design Certified by C.S.A. (Canadian
Standards Association) for use with Natural and Propane
Gases. They are constructed and hydrostatically tested for
a maximum working pressure of 50 psi in accordance with
A.S.M.E. Boiler and Pressure Vessel Code Section IV Stan-
dards for cast iron heating boilers.

* MBH = 1,000 Btuh = British Thermal Unit Per Hour. Boilers are equipped for altitudes up to 2,000 feet only. U.S.A. Only - For altitudes above 2,000
feet, ratings should be reduced at the rate of 4% for each 1,000 feet above sea level. Canada Only - Boilers may be used at high altitude (2,000-4500
feet/640-1350m) by using a certified field conversion kit, resulting in a 10% de-rate. Contact Provincial authority having jurisdiction for installations
above 4500 ft (1350m) above sea level.
+ Heating Capacity based on D.O.E. (Department of Energy) test procedure.
New York City MEA Number 484-84-E Vol. IV.
The Ratings marked "Net I=B=R Ratings" indicate the
amount of remaining heat input that can be used to heat
the radiation or terminal units. The Net I=B=R Ratings
shown are based on an allowance of 1.15

loss of the building.
The manufacturer should be consulted before selecting a
boiler for installations having unusual piping and pickup
requirements.
