WARNING: Electrical Device
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.
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.
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.
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.
Component and heating cable ends must be kept dry
before and during installation.
Fire-resistant thermal insulation materials should be used.
For use with Nuheat R8P5, R13P8 and 13FP cables.

HOWTOCREATEASPLICE (COMBININGTWOCABLES)
Preparing the heating cables:
1. Allow 6” of extra length on each heating cable. Trim
cables evenly.
2. Slide the three black heat shrinks (3½" long, 8" long,
8½" long) down one of the cable lengths for use later.
3. From the end of the cable, strip away 3" of outer
jacket using utility knife. Do not cut into inner jacket.
4. Push back braid to loosen. Spread apart braid, bend the
heating cable and work it through the opening in the braid.
5. Twist the braid into a pigtail.
6.  Usingwirecutter,cutoffapproximately1"oftheexposed

allow the heating cable to fit easily into the blue heat
shrink crimps in Step 14.
10. Repeat steps 1-9 on the other two cable lengths.
11. Locatethepieceofmasticstripandcutthestripinto
