I. Product Description, Specications and Dimensional Data
Alpine™ Series boilers are condensing high efciency
gas-red direct vent hot water boilers designed for use
in forced hot water space or space heating with indirect
domestic hot water heating systems, where supply water
temperature does not exceed 210°F. These boilers have
special coil type stainless steel heat exchangers, constructed,
tested and stamped per Section IV ‘Heating Boilers’ of
ASME Boiler and Pressure Vessel Code, which provide a
maximum heat transfer and simultaneous protection against
ue gas product corrosion. These boilers are not designed
for use in gravity hot water space heating systems or
systems containing signicant amount of dissolved oxygen
(swimming pool water heating, direct domestic hot water
heating, etc.).
