A screwdriver is used to open the braid at this pucker, allowing the cable to be bent and worked through the opening. The inner jacket is then lightly scored and peeled off, exposing the core. The core is notched, and the bus wires are peeled away from it. The core is scored between the buswires, snapped, and then peeled from the bus wires. Any remaining core material is removed, and the braid is pulled tight to form a pigtail. The measurement for inner jacket removal is 6 1/2 inches (165 mm).

Step 5B: Prepare XTV and KTV Cable

Push the braid back to create a pucker. Use a screwdriver to open the braid at the pucker. Bend the heating cable and work it through the opening in the braid. Lightly score the inner jacket around and down as shown, then peel off the inner jacket. Cut and remove all fiber strands. Score and remove the center spacer. Remove any remaining fiber material from the bus wires. Pull the braid tight to make a pigtail.

Diagram description: Similar to Step 5A, but illustrates the removal of fiber strands and a center spacer from the XTV and KTV cable construction. The measurement for inner jacket removal is 6 1/2 inches (165 mm).

Step 5C: Prepare VPL Cable

Push the braid back and bunch it as tight as possible. Lightly score the inner jacket around and down as shown, then peel off the inner jacket. Unwind the heating element, cut, and remove it as shown. Lightly score the clear jacket around and down as shown. Bend the heating cable to break the jacket at the score, then peel off the jacket. Push the braid forward. Use a screwdriver to open the braid. Bend the heating cable and work it through the opening in the braid. Remove insulation from the ends of the bus wires. Pull the braid tight to make a pigtail.

Diagram description: Shows the preparation of VPL cable, which has a distinct construction including a heating element and clear jacket. Steps involve bunching braid, removing inner and clear jackets, preparing the heating element, and then preparing the bus wires. Measurements of 6 inches (152 mm) and 1/2 inch (13 mm) are indicated.

Step 5D: Prepare HTV Cable

Push the braid back to create a pucker. Use a screwdriver to open the braid at the pucker. Bend the heating cable and work it through the opening in the braid. Score the inner jacket and conductive core around and down as shown. Peel off the inner jacket. Flip the cable 180° and score the other side of the inner jacket and conductive core. Remove the inner jacket and conductive core using needle-nose pliers. Score and remove the center insulation. Remove any remaining material from the bus wires. Pull the braid tight to make a pigtail.

Diagram description: Illustrates the preparation of HTV cable. Steps include preparing the braid, scoring and removing the inner jacket and conductive core from both sides (requiring a 180° flip), and then preparing the bus wires. Measurements of 6 1/2 inches (165 mm) are indicated.

Step 6: Mark Jacket

Mark the jacket as shown.

Diagram description: Shows a tool marking the heating cable jacket at a specific point. The measurement indicated is 5/8 inch (15 mm).

Step 7: Prepare Bus Wires and Guide Tubes

If needed, re-twist and straighten the bus wires, then insert them into the guide tubes as shown. Make sure all strands go into the tubes.

Diagram description: Shows the bus wires being inserted into guide tubes. A warning "Make sure all strands go into the tubes" is present.

Step 8: Apply Core Sealer

Push the core sealer onto the heating cable to the mark made in step 6. Note: Extra force may be required for larger cables or at lower temperatures.

Step 11: Insert Cable into Stand

Pull the heating cable back into the stand so 1 inch (25 mm) is exposed, as shown. Use cable lubricant if needed.

Diagram description: Shows the heating cable being pulled back into the stand assembly. A measurement of 1 inch (25 mm) is indicated for the exposed cable length.

Step 12: Fasten Stand to Pipe

Fasten the stand to the pipe with the label facing the desired direction of the box opening. Do not pinch the heating cable. Loop and tape extra heating cable to the pipe. ⚠️ CAUTION: To avoid pinching the heating cable, be sure the cable is not under the pipe strap. ATTENTION (French): Pour éviter de pincer le câble chauffant, assurez-vous que le câble ne se trouve pas sous la sangle du tuyau.

Note: For 1 inch (25 mm) and smaller pipes, use the JBS-SPA adapter (purchased separately) and install it between the stand and the pipe. Position the adapter this side up.

Diagram description: Shows the stand assembly fastened to a pipe using a pipe strap. The heating cable is routed. Glass cloth tape is shown. The JBS-SPA adapter for small pipes is illustrated, with an indication of its correct orientation ("Position adapter this side up").

Step 13: Screw Box onto Stand

Screw the box onto the stand until it stops. Do not overtighten.

Diagram description: Shows the junction box being screwed onto the stand assembly.

Step 14: Optional - Change Box Opening Direction

To change the direction of the box opening: Loosen the locknut using adjustable pliers. Lift the box and rotate it. Make sure the tab on the threaded piece fits into one of the four notches in the box. Tighten the locknut.

Diagram description: Illustrates the process of changing the box orientation. It shows loosening a locknut, lifting and rotating the box, aligning a tab with a notch, and then tightening the locknut.

Step 15: Secure Box with Cable Tie

Insert a cable tie through the slots on the stand and box, and tighten firmly to prevent box rotation. Trim any excess tie.

Diagram description: Shows a cable tie being inserted through slots on the stand and box and tightened to secure the box. The excess tie is shown being trimmed.

Step 16: Connect Wires to Terminals

This kit uses spring clamp style terminals. Terminals use a steel spring to clamp the wire to provide improved vibration resistance, reduced maintenance, and faster installation. To connect wires, firmly insert a slotted screwdriver into the square hole (①) to open the spring. When fully inserted, the screwdriver will lock into place, allowing you to remove your hand and insert the wire into the round hole (②). Remove the screwdriver to clamp the wire. The wire is held securely against the bus bar for low contact resistance over time without the need to periodically retighten screws. Use the green terminal for the braid and ground wire.

Diagram description: Illustrates the operation of the spring clamp terminals. A screwdriver is inserted into a square slot (①) to open the spring clamp, allowing a wire to be inserted into a round hole (②). Removing the screwdriver clamps the wire. The diagram also shows a green terminal designated for braid and ground wire.

Step 17: Install Conduit and Terminate Wires

Install conduit and fittings as shown. To minimize loosening due to pipe vibration, use flexible conduit. Pull in power and ground wires, strip off 1/2 inch (13 mm) of insulation, and terminate.

Diagram description: Shows conduit and fittings being installed, including a water-tight conduit seal and a conduit drain. A measurement of 1/2 inch (13 mm) is shown for wire stripping. A note states: "Make sure conductors are not exposed. nVent recommends the use of a conduit drain to prevent water condensation build-up."
