Water Coil Piping

Figure 49 and Figure 50 illustrate typical water coil piping
configurations.
Water coils are self-venting only if the water velocity
exceeds 1.5 feet per second (fps) in the coil tubes. See the
unit submittals for coil water velocity. If the water velocity
is below these minimums, vent the coil by one of the
following methods:
1. Install an air vent in the top pipe plug tapping of the
return header.
2. When the return line rises above the top of the coil,
vent from the top of the return header horizontally to
the return piping.
