WinterGard®Splice and Tee Kit with End Seal
Description
The WinterGard®H910 Splice and Tee Kit is for use with WinterGard
self-regulating heating cables to make splice, tee, and end seal con-
nections. The kit contains materials for one splice and one end seal, or
one tee connection and one end seal. This kit does not provide a power
connection; use an H900 or H908 power connection kit for a complete
installation.
Applications
Use the H910 kit with the following WinterGard heating cables:
H311, H611, H612, H621, and H622. All are designed for pipe
freeze protection in dry locations, but H612 and H622 cables are
designed for both wet and dry areas, as well as for roof and gutter
de-icing. The cable type is printed on the outer jacket of the cable.
Tools Required
• Diagonal Cutters • Needle nose pliers
• Utility knife • Heat gun or torch
• Crimp tools (Ideal 30-425 and T&B WT112M or WT2000)
• Hammer and nail (for gutter/downspout applications only)
Installation and Support
The minimum installation temperature for this kit is 0°F (–18°C).
See the WinterGard Application and Design Guide (H53585),
H900, or H908 installation instructions for design information.

WARNING:
This component is an electrical device that must be
installed correctly to ensure proper operation and to
prevent shock or fire. Read these important warnings
and carefully follow all the installation instructions.
• To minimize the danger of fire from sustained
electrical arcing if the heating cable is damaged
or improperly installed, and to comply with the
requirements of Tyco Thermal Controls, agency
certifications, and national electrical codes, ground-
fault equipment protection must be used. Arcing may
not be stopped by conventional circuit breakers.
• Bus wires will short if they contact each other. Keep
bus wires separated.
• Keep components and heating cable ends dry before
and during installation.
• The black heating cable core is conductive and can
short. It must be properly insulated and kept dry.
• Component approvals and performance are based on
the use of Tyco Thermal Controls-specified parts only.
Do not use substitute parts or vinyl electrical tape.
• Leave these instructions with end user for reference
and future use.

• After the connection has cooled, fold
over the connection and fasten it
with the third cable tie.
• Secure heating cable with down-spout
hanger (H915).
• Fasten clamp tie to center of connection.
• Use a hammer, nail, and clamp tie to
secure connection and keep it off of the
gutter bottom as shown.
• Shrink the tube completely. Start at end farthest
from the cap and work toward the open end.
• Keep heating after tube has shrunk, to melt
adhesive and mastic inside tube. Total heating
time should be about 5 minutes.
Important: Additional heat
is needed after the tube is
shrunk to melt mastic and
adhesive inside.
• Immediately after
shrinking, pinch the end
of the tube with needle-
nose pliers until the
end stays sealed; this
normally takes
10 seconds.
