I. Product Description, Specifications and Dimensional Data
Phantom X Series boilers are condensing high efficiency
gas-fired 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
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 hot water
heating, etc.).
This manual is for use with boilers having a part number
ending in “C” (example: PHNTM399CHNL2HUC).
