PREPARE FOR INSTALLATION
1. Store the heating cable in a clean, dry place.
2. Inspect for any mechanical damage prior to installation.
3. Warranty is void if non-King accessories are used. King approved
accessories include:
- SR1K5 Downspout hanger bracket
- SRK13 Roof clips
4. Gutters and downspouts must be free of leaves and other debris.
5. Plan the routing of the heating cable for roof and gutter deicing.
ATTACH THE HEATING CABLE ON ROOFS
1. Loosely loop the heating cable on the roof at the overhang area. Pull
the bottom of each heating cable loop over the roof edge and, using a
UV-resistant cable tie. Connect the bottom of each loop to the cable
running in the gutter. This will ensure a drainage channel for the
melting ice to drain off the roof and into the gutter and downspout. The
cable in the gutter should remain against the bottom of the gutter as
shown in Figure 6 (Standard Roof) and Figure 7 (Metal Roof).
2. Extend the top of each heating cable loop beyond where the wall joins
the roof.
3. Trace two-thirds of the way up each valley with a double run of heating
cable as shown in Figure 8.
4. Use SRK13 roof clips to route heating cable up and down the edge of
the roof according to the tracing height noted in the tables above and
shown in Figures 11 and 12. Route the heating cable in such a way as
to prevent abrasion to the cable jacket.
5. One SRK13 kit contains 25 roof clips for approximately 17 linear feet
of the roof edge.
6. Roof clips may be attached to a shake or shingle roof using nails or
screws. Roof clips may be attached to a metal roof using nails, screws,
or adhesive. Reseal the nail or screw holes if necessary before
installing heating cable in the clips.
7. A barrier (snow fence) can be placed on the roof above the heating
cable. This prevents damage to the cable and keeps the roof brackets
from tearing loose during ice slides. The heating cable can be
attached to the barrier with UV-resistant cable ties, instead of using
roof clips. The use of other materials, such as wire, may cause
damage to the heating cable and will void the warranty.
