Pentair Raychem WinterGard H311100 User manual

Raychem WinterGard self-regulating heating cables provide
convenient, reliable freeze protection for a wide variety of pro-
fessionally 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 provided 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 protect-
ed junction box.
For detailed information on roof and gutter de-icing applica-
tions, please refer to the WinterGard Wet Design, Installation
and Maintenance Guide (H56804).

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 elec-
trical arcing if the heating cable is damaged or
improperly installed, and to comply with the
requirements of Pentair Thermal Management,
agency approvals, and national electrical 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
installation 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 substitute parts.

WinterGard Selection Guide
Selection Tables
Use one of the tables below to help select
the correct WinterGard heating cable for
your application. (Consult the
Commercial and Residential Application
and Design Guide or H900/H908
Installation Instructions for complete sys-
tem design information.)
Use Table 1 to select heating cables for
insulated metal pipes. Use Table 2 for
insulated plastic pipes.
Read across the table to find your pipe
diameter, then drop down to the line corre-
sponding to the lowest air temperature for
that application and the correct insulation
thickness. The cell at that intersection has
a particular shade and may have a num-
ber.
The shade indicates which heating cable to
use (key to the shades appears to the left of
Table 1). A number in the cell represents
the spiraling ratio (feet of heating cable per
foot of pipe). If no number appears in the
cell, straight trace the pipe. If a number
does appear in the cell, spiral trace the
pipe. If your spiraling ratio is 2.0,
multiple-trace the pipe using two straight
traces at the 4 o’clock and 8 o’clock posi-
tions.
If your spiraling ratio is 3.0, multiple-trace
the pipe using three straight traces at the
11 o’clock or 1 o’clock position and at the 4
o’clock and 8 o’clock positions.
