Figure 20. Treatment Tank
Condensate Piping for Multiple Boilers
The number of condensate treatment tanks required for multiple boiler installations depends on the
total amount of condensate produced by the system. As a general rule, CB recommends a maximum
of 4 boilers per tank, with total BTU per tank not to exceed 8,000,000.
See figures below for suggested piping. When using the combo tank, supply make-up water at the
connection shown. An internal float in the tank activates the make-up water valve.
