Recirculation Connections
H
Pipe domestic hot water supply piping
with tank as illustrated. Connections
must be accessible for service (use
factory supplied adaptors).
Connection sizes are provided in
section entitled Orientation and
Dimensions on page 10.
H
Install recirculation pump, flow check
valve and recirculation timer (for
shut-down during off-hours where
feasible) on the recirculation piping
side.
H
Gravity circulation of the recirculation
system is restricted due to the
upward-curved domestic hot water
discharge piping inside the tank.
H
Connect tank battery to existing
recirculation piping. Cap off unused
recirculation connections of individual
tanks.
H
Saving Energy
A timer on the recirculation pump
reduces the heat loss significantly in
commercial applications during times
when no or reduced demand for
domestic hot water occurs.
