same as any other. To achieve this, the following is necessary:
1.
The cold water manifold (cold header assembly) must be designed to balance the flow to each unit i.e.
each branch line must be the same diameter and length and be fitted with identical ball or gate valves (refer
to diagram below).
2.
The heating
(heating header assembly) must
be designed to balance the flow
from each unit i.e. each branch
line must be the same diameter
and length and be fitted with
identical ball or gate valves (refer
to diagram opposite).
3.
The hot water manifold (hot
header assembly)
designed to balance the flow from
each unit i.e. each branch line
must be the same diameter and
length and be fitted with identical
ball or gate valves (refer to
diagram opposite).
