self-regulating heating
cables provide convenient, reliable freeze pro-
tection for a wide variety of professionally
installed residential and commercial water-pipe
and roof-and-gutter de-icing applications in
nonhazardous areas. This data sheet is
designed to assist in cable and accessory
selection and basic circuit design of pipe-
freeze-prevention applications.
Complete design guidelines, installation
instructions, and safety information are pro-
vided in the Commercial and Residential Self-
Regulating Heating Products Application and
Design Guide (H53585), the H900 Power
Connection Kit, the H908 Plug-in Power
Connection Kit, and the H921 120-V ground-
fault protected junction box.
For detailed information on roof and gutter de-
icing applications, please refer to the
WinterGard Wet Design, Installation and
Maintenance Guide (H56804).

Construction
Pipe Applications
WinterGard systems must be installed correctly to
ensure proper operation and to prevent shock or fire.
Carefully read and follow the Commercial and Residential
Self-Regulating Heating Products Application and Design
Guide and the H900 series connection kit installation
instructions.
• Use only in ordinary (nonhazardous) areas. Do not
expose to any chemicals, oil or grease.
• In wet areas, use only WinterGard Wet.
• 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 approvals, and national electri-
cal codes, ground-fault equipment protection must be
used on each heating cable branch circuit. Arcing may not
be stopped by conventional circuit protection.
• This selection guide does not take the place of the instal-
lation instructions included in the Commercial and
Residential Self-Regulating Heating Products Application
and Design Guide and in the H900 series accessory kits.
• System approvals and performance are based on the use
of only H900 series accessories with WinterGard heating
cables. These accessories must be used. Do not substi-
tute parts.
