Step 4.

Attach the heating cable to the pipe.

4A. Prepare to install the heating cable.

Begin the installation at the electrical outlet. Leave at least

1 foot (30 cm) of extra heating cable so the ground-fault unit can be secured to the outside of the thermal insulation, as shown in Figures 1 and 2. This will relieve any strain on the heating cable or plug. However, be careful not to leave heating cable hanging in a loose loop where it could be accidentally snagged and pulled out.

Make certain you have removed any old heating tapes and insulation.

Important: The ground-fault unit and plug must be kept dry. It is important to include the drip loop to prevent water from getting into the ground-fault unit.

Multiple run method

When two or more runs are required, install the heating cable in the 4 o’clock and 8 o’clock positions as shown in Figure 4. When three runs are required, install the heating cable as shown in Figure 5.

4C. Tape the heating cable and end seal to the pipe.

Fasten the heating cable to the pipe at 1-foot (30-cm) intervals, using two or three thicknesses of 9610 applica- tion tape or equivalent.

Provide extra heat at valves and spigots by wrapping each with 1 foot (30 cm) of additional heating cable, overlap- ping as required.

If you have excess heating cable at the end of your pipe, double it back along the pipe where the insulation will completely cover it as shown in Figure 6. Using 9610 application tape or equivalent, tape the end seal to the pipe as shown in Figures 1, 2, and 6.

Single run method

Run the heating cable in a straight line approximately a third of the way up from the bottom of the pipe, as shown in Figure 3.

Important: In a crock or standpipe, run the Frostex heating cable down and back up the pipe (as shown in Figure 6), so that the end seal is well above the ground level and will not be sitting in water.
