Versatility at Its Best
FD Series boilers are available with oil, gas or gas/
oil burners. As a forced draft boiler, the FD Series
eliminates the need for external draft devices, such
as a high chimney or mechanical draft equipment.
The vertical design of the FD Series provides a smaller
footprint per gross output than conventional boilers
of comparable ratings. The FD water boiler is rated for
30 PSI maximum allowable working pressure, and is
available in eleven sizes from 262 to 1617 MBH output.
