Series Condensing Boiler Combi Manual

Rinnai requires hydraulic separation between the boiler and central heating system. Hydraulic
separators allow for no pump curve matching or flow calculation; this is ideal for multi

-

temperature

and multi

-

zone systems.

Examples of Hydraulic Separation

Closely spaced tees and low loss headers are common examples of hydraulic separators and can be
used to separate the boiler loop from the central heating loop.

Low Loss Header

Distance no

more than four

pipe diameters

IMPORTANT

For closely spaced tee installations, the
separation at the header is to be no
more than four pipe diameters.

Closely Spaced Tees
