STEP 2 (continued)
4. One SRK13 kit contains 25 roof clips for approximately 17
linear feet of the roof edge.
5. 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. See SRK13 installation instructions for
additional details on mounting roof clips.
6. 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.
STEP 3: ATTACH THE HEATING CABLE ON VALLEYS
1. Trace two-thirds of the way up each valley with a double
run of heating cable as shown in Figure 7.
STEP 4: INSTALLING THE CABLE IN GUTTERS AND
DOWNSPOUTS
1. Run the heating cable in the gutters and into downspouts,
end the cable in a loop at the bottom of the downspout and
then run the cable back up the downspout using a tie
wraps to fasten it as shown in Figure 8. Permanent
attachment of the cable to the gutter bottom is not
necessary.
2. Use the King SRK15 downspout brackets at the transition
of the gutter and downspout to protect the cable from
fraying. Refer to the SRK15 installation instructions for
more details.
3. Route and secure cable with care to avoid mechanical
damage during installation or maintenance from such
things as ladders, etc.
