1-2 Boiler Nameplate and Model Number

The Boiler Name Plate
The following illustration is an accurate depiction of the nameplate found on the rear side of the boiler. You will also find
an ASME nameplate on the inlet pipe with some of the same information.
A. Boiler description
B. Model number
C. Serial number
D. Minimum relief valve capacity
E. Maximum Btu/Hr fuel input
F. Maximum Btu/Hr output**
G. Boiler horsepower
H. Square feet of heating surface
I. Minimum Btu/Hr fuel input*
J. Minimum Btu/Hr output***
K. Gross E.D.R.
L. Max. allowable working press.***
M. Supply voltage
N. Electrical supply Hertz
O. Electrical supply Phase
P. Required Amperage
Q. Motor amp draw****
R. Control voltage****
S. Control amp draw****
T. Min. Gas pressure*****
U. Max. Gas pressure*****
V. Manifold gas pressure*****
W. Fuel type (See model #)
X. Gallons per hour oil****
Y. Int. Group Prim Safety****
Z.
Minimum distances btw. boiler and adjacent construction.
* Minimum Btu/Hr ratings apply to high-low and modulating type boilers only.
** Boiler output ratings are based on factory tests under appropriate conditions. Field results may vary.
*** Maximum allowable working pressure for the boiler. Relief valve set pressure should not exceed the lowest MAWP of any component in your system.
**** Applies to forced draft type burners only
***** Minimum and maximum gas pressure values are measured at the point of connection to the boiler gas train. Manifold gas pressures are measured
after the gas train.
