INSTALLATION PROCEDURES
Maintenance Check List. . .
As part of an annual maintenance program or after any work
(repair or alteration) has been performed on or near the heat
traced piping, the following steps should be performed:
1. Visually inspect the pipe's thermal insulation looking for any
areas where the insulation appears repaired or replaced.
Any suspect areas should be examined for damage to the
heating cable. Verify that any new/repaired insulation meets
the specification.
2. While inspecting the insulation, verify that it is completely
dry. Wet insulation will not only cause temperature mainte-
nance problems, but could also signal a more serious prob-
lem that could cause damage to the cable and the facility.
3. Test for ground-fault protection by manually tripping the
push-to-test button on the device (remember to reset after
the test).
4. Using a calibrated thermometer, check the water tempera-
ture at the water heater to be certain that it is within the
desired range.
5. Again, using a calibrated thermometer, check the water
temperature at various tap locations that are heat traced. Al-
low sufficient time for water to pass any unheated portion of
water line.
6. Heating cable should tested with a megohmmeter (megger)
at the power distribution panel by a qualified electrician.
7. Record any observations on the project's as-built drawings
and any maintenance log kept for facility.
Do Not enter any power connection point, ca-
ble splice or end termination while heating cable
is energized. Disconnect power to heating cable
and seek qualified assistance.
