Heating Cable Installation
Raychem-IM-H57548-HWATsystem-EN 16/08
• If the cable is on the wrong side of an obstacle
such as a crossing pipe or I-beam, you will need
to reinstall it or cut and splice it.
• When installing the heating cable, the cable
must not
be compressed or pinched between
two objects. Wall and floor penetrations and pipe
hangers are particular areas of concern.

penetrations
• Run insulation through the pipe hanger ensuring
that the pipe is not resting on the heater.

• When making floor or wall penetrations, make
sure the hole is large enough to accommodate
the pipe and the thermal insulation. When sealing
around pipes at floor penetrations, avoid damag-
ing or cutting the heating cable, or pinching it
between the pipe and the concrete.
