Model CFC ClearFire Commercial Boilers
37 Rev. 05-2012
Hot Water Piping Primary/secondary pumps are not necessary with the Model CFC boiler. As its
design is such that no minimum flow is required, variable speed or on/off pumps
may be employed in the piping scheme.
Typical piping arrangements are shown in figures B5-33 through B5-45.
