INTRODUCTION

Series L and WL Water Tube Boilers

The Columbia Models L and WL are water tube boilers designed for hot water, and/or low pressure

steam applications. These units are manufactured to the specifications set forth by Section IV of the

ASME Boiler and Pressure Vessel Code. Boilers are inspected and stamped for conformity to require-

ments of the National Board of Boiler and Pressure Vessel Inspectors. All boilers are designed to be

fired using No. 2 fuel oil, and/or natural, manufactured, or liquid propane (LP) gas, and are powered

by standard AC electrical service.

CWH Series Steam Boiler

The CWH Series is a steam boiler used for indirect hot water applications. This boiler classification

consists of all L and WL Series Boilers providing heat transfer to one or two coils, depending on boil-

er size. The boiler is a self contained unit allowing a steam cavity above the water line for expansion.

Columbia hot water and low pressure steam boilers are typically shipped knocked down (unassem-

bled), but are also available factory packaged. All boilers are furnished with a jacket kit, burner, and

boiler trim. Boiler trim consists of the operating and limit controls, pump and/or low water cut off

(LWCO) controls, a safety valve, and a smokehood for all WL Series Boiler Models, and Model L-32.

Factory packaged boilers are fully assembled and test fired.
