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, sectional cast
iron boilers Design Certified by C.S.A. (Canadian Standards Associ-
ation) 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 Sec-
tion IV Standards 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 by using a certified field conversion kit, resulting in a 10% de-rate.
+ 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 re-
maining 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 in accordance with the factors shown on the I=B=R Standard as
published by The Hydronics Institute.
