III. Product Rating, Specifications, and Dimensional Data
AMP boilers are condensing, high-efficiency, gas-fired, hot water boilers designed for space heating systems or indirect
domestic water heating, where supply water temperature does not exceed 190°F. These boilers have special coil type
stainless steel heat exchangers, constructed, tested, and stamped per Section IV of the ASME Boiler and Pressure Vessel
Code, which provide maximum heat transfer and simultaneous protection against flue gas product corrosion. These
boilers are not designed for use in gravity hot water space heating systems or systems containing significant amount of
dissolved oxygen (swimming pool water heating, direct domestic water heating, etc.).
