Condensate Piping For Multiple Boilers - CleaverBrooks CFC Operation, Service & Parts Manual

2. 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 one
tank per 5-6 million BTU/hr of total boiler capacity. Model CFC
capacities are as follows:
CFC Model BTU/hr
3300 3,300,000
2500 2,500,000
1800 1,800,000
1500 1,500,000
1000 1,000,000
750 750,000
500 500,000
See Figure 2-36 and Figure 2-37 for suggested piping. A drain trap
is built into the condensate tank. Make-up water must be supplied
at the connection shown in order to prevent flue gas from entering
an idle boiler. An internal float in the condensate tank activates the
make-up water valve.
