11. Use insulated bus wire crimps to connect each set of
bus wires together. Slide heat shrink cap over bus wire
crimps. It is not necessary to heat shrink the cap.

Heat Shrink End Seal
Model #: 13HSES & 9HSES
In order to ensure proper operation and prevent shock
or fire, all products must be installed correctly. Read all
warnings and follow all installation instructions.
Nuheat Freeze
Protection Products
EQUIPMENT REQUIRED:
12. Position the 6” heat shrink tube over the entire tee or
splice connection, aligning the back edge of the tube with
the mastic strip applied in step 5. Heat shrink down until
the inner sealant starts to appear.
Utility Knife
Wire Cutter
Heat Gun
Needle-nose pliers
Measuring tape
Ground-fault equipment protection must be used to
minimize the danger of fire from sustained electrical
arcing if the heating cable is damaged or improperly
installed and to comply with Nuheat requirements,
agency certifications and national electrical codes.
Conventional circuit breakers may not stop arcing.
KIT CONTAINS:
5 – Heat shrink cap
5 – Heat shrink tube ( 1” x ½” dia.)
HOW TO CREATE AN END SEAL:
1. Strip and remove outer jacket ¾” from the end. Do not
cut into inner jacket. Unravel ground braid and remove.
The heating cable core is conductive and can short if
not properly insulated and kept dry.
Heating cable core bus wires can overheat and short
when damaged. When cutting the cable jacket or core,
do not break bus wire strands.
13. Crimp and hold end of tube closed while still hot and hold
for 15 seconds to ensure seal.
2. Place heat shrink tube over cable and leave 3/8” of the
tube hanging off the cable. Heat shrink the tube and
while still hot, use pliers to pinch overhang together to
seal end; hold for 15 seconds.

Heating Cable
14. For straight through splice only: To avoid the risk
of serious burns, wait until the 6” heat shrink tube has
cooled completely. Once the 6” tube is cool to the touch,
fold back one cable against heat shrinked tube and
attach with third cable tie.
NOTE: Complete heat shrink end seal at the opposite
end of the heating cable by following the Heat Shrink
End Seal instructions included in this booklet.
Do not substitute parts or use electrical tape.
Component approvals and performance characteristics
are based on Nuheat specific parts only. Substitution
will void approvals, warranties and performance claims.

5. Lightly score around and down the inner jacket 6.5”
from the end of the heating cable and remove.
6. Remove 1 ½” of the conductive core from the tip of the
cable exposing the bus wires. Cut down the center of
the conductive core to separate the two bus wires. Trim
away just enough conductive core to allow the bus wire
to fit in a black heat shrink tube.
NOTE: Repeat steps 1 to 4 for each cable section.

5. Stretch and wrap a mastic strip around the outer jacket
on each heating cable section, 1” from inner jacket cut.
6. Wrap a mastic strip around the heating cable extending
¼” past the end.
KIT CONTAINS:
ADDITIONAL MATERIALS REQUIRED:
• Certified junction box for suitable location
KIT CONTAINS:
3 – Wire nuts
2 – 1” black heat shrink tubes
2 – Black bus wire heat shrink tubes
1 – Green / Yellow ground wire heat shrink tube
1 – End seal heat shrink cap
1 – Compression washer, grommet & sealing gasket
1 – Lock nut
1 – Caution label (End seal)
7. Slide a black heat shrink tube over each trimmed bus wire
until the tube meets the inner jacket. Heat shrink.
8. Slide green / yellow heat shrink tube over pigtailed braid
and heat shrink.
9. Slide the 1” heat shrink tube over both covered bus wires
until the tube meets the outer jacket. Heat shrink until
inner sealant flows from both ends. Using pliers, pinch
tube between the two bus wires and hold for 15 seconds.
HOW TO CREATE A TEE / SPLICE:
NOTE: All illustrations show a tee connection. To perform a
splice, follow all instructions using only 2 heating cables.
1. Allow 12” of extra heating cable. Trim cables evenly.
HOW TO CREATE A POWER CONNECTION:
NOTE: Nuheat recommends conducting continuity
testing at this point of the installation.
1. Slide the compression washer, sealing gasket and
grommet onto cable.
6 – Mastic strips
3 – Cable ties
3 – End seal heat shrink caps
2 – 1” black heat shrink tubes
2 – Insulated bus wire crimps
2 – Caution labels (End seal & Splice / Tee)
1 – Un-insulated braid crimp (copper)
1 – Over-jacket heat shrink tube (6” long)
1 – Black cloth tape (6” long)
4. Position braid on one side of cable and twist into a pigtail.
7. Align the heating cable sections together; ensure all
braids are on the same side of the cables. Press mastic
strips firmly together and fasten cable ties 6” and 9”
from end.
8. Twist together braid pigtails and slide un-insulated
braid crimp to within ¼” of cable. Compress the
un-insulated braid crimp and remove excess pigtail.
10. Slide compression washer, grommet and sealing gasket
over heat shrinked wires.
2. At the end of the cable, strip away 2” of outer jacket.
Do not cut into inner jacket.
2. Lightly score around and down outer jacket 7” from the
end of the heating cable. Bend heating cable to break
jacket at score; peel off outer jacket.
3. Push back braid to loosen. Spread apart braid, bend the
heating cable and work it through the opening in the braid.
11. Insert the heating cable into a junction box approved for
the application. Use the sealing gasket and lock nut to
securely connect the cable to the junction box.
12. Make the final electrical connections within the junction
box and ensure the box is sealed in accordance to
manufacturer’s instructions.
3. Unravel the braid back to outer jacket. Position braid to
one side of the heating cable section.
9. Fold the crimped braid back against the heating cables.
Wrap cloth tape evenly around un-insulated braid crimp
and heating cables covering crimp completely.
10. Select one bus wire from each cable and twist together.
Repeat with remaining bus wires (do not twist bus wires
from the same cable together).
4. At the end of the cable, strip away 1” of inner jacket
and remove conductive core, exposing bus wires.
NOTE: Complete heat shrink end seal at the opposite
end of the heating cable by following the Heat Shrink
End Seal instructions included in this booklet.
NOTE: Nuheat recommends conducting continuity
testing at this point of the installation.
