Refer to section “8.3.1 Equivalent Feet of Pipe Per Fitting” for more information on determining the maximum
equivalent pipe length.
IMPORTANT
If more than 40 equivalent feet of plumbing is needed with the I-Series Boiler, Rinnai recommends the use
of hydraulic separation with an external circulation pump. Hydraulic separation uses primary/secondary
piping to separate the boiler from the heating system. Hydraulic separator examples include a low loss
header (field-supplied), closely spaced tee (field-supplied), or the Primary-Secondary Heating Kit offered
by Rinnai (part # 807000212).
