A) GENERAL
The installation of the unit shall be in accordance with state and local regulations.
B) FREIGHT CLAIMS
All units should be inspected for damage upon arrival. Concealed damage claims should be filed
immediately against the carrier by the consignor. The carrier is responsible for taking prompt
action on all claims.
C) SIZING
Replacement boilers should not be sized from the firing rate of the old boiler; a DOE sponsored
study indicated 65% of the heating units in U.S. homes are substantially oversized. A complete
heat loss calculation of the structure is necessary to choose the proper size unit to install. The boil-
er should be sized to within 25% of the actual calculated heat loss of the structure. Over sizing
will result in short cycling and inefficient operation.
