Rinnai I-Series Condensing Boiler Solo Manual
Rinnai recommends hydraulic separaon between the boiler and central heang system. Hydraulic
separators allow for no pump curve matching or ow calculaon; this is ideal for mul-temperature
and mul-zone systems.
Examples of Hydraulic Separaon
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 heang loop.
Low Loss Header
Distance no
more than four
pipe diameters
IMPORTANT
For closely spaced tee installaons, the
separaon at the header is to be no
more than four pipe diameters.
