Dielectric Fittings
A Dielectric Fittings Kit (Part No H3189)
is included with the water heater.
It is essential that dielectric fittings are
installed in
both
the hot water outlet
and cold water inlet sockets. Dielectric
fittings do not need to be installed in the
unused hot water outlet or cold water
inlet sockets. Please also refer to the
Plumbing Connections section.
Failure to install both dielectric
fittings may void the warranty.
To install a dielectric fitting:
1. Apply thread tape to both ends of
the brass nipple and install it into
the socket. Tighten the nipple to a
recommended torque of
~70 Nm
.
2. Install the dielectric fitting to the
brass nipple, with the knurled end
toward the tank. Tighten the fitting to
a recommended torque of
~40 Nm
.
3. Connect the pipework to the
dielectric fitting. If brazed
connections are to be used, remove
all insulation components from the
dielectric fitting to prevent damage.
Reassemble the fitting once brazing
is complete and the fittings are cool.
