Installation
I. GENERAL
CWL-GS Series hot water boilers are high quality, high efficiency gas fired vertical fire tube heating units.
The in stal la tion of the unit shall be in accordance with regulations of the authorities having jurisdiction.
Refer to Local installation Codes for Gas Burning Equipment, for recommended installation practice.
The CWL must be installed with the factory assembled jacket intact.
II. FREIGHT CLAIMS
All units should be inspected for damage upon arrival. Concealed damage claims should be filed
immediately against the carrier by the consignee. The carrier is responsible for taking prompt action on all
claims.
III. SIZING
A complete heat loss calculation of the structure is necessary to choose the proper size unit.
Oversizing will result in short cycling and inefficient operation. In order to insure proper sizing of the unit,
domestic hot water re quire ments and the structure heat load must be calculated.
Replacement boilers should not be sized from the firing rate of the old boiler. A DOE sponsored
study indicates 65% of the heating units in U.S. homes are substantially oversized.
