FIRE AND SHOCK HAZARD
. This product 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 Pentair Thermal Building Solutions,
agency certifications, and the National Electrical Code, ground-fault
equipment protection must be used on each heating cable branch
circuit. Arcing may not be stopped by conventional circuit protection.
• Use only fire-resistant insulation materials such as fiberglass
wrap.
• Do not damage the heating cable and cord connector. Remove
any damaged cables from service immediately.
• Do not use any wire or metal clamps to attach the cable to the
pipe. Use tape (1/2 inch wide to 1 inch wide) or plastic cable ties.
• Leave these installation instructions with the user for future
reference.

HEATING CABLE SELECTION
FrostGuard 240 V (FG2) heating cable
selection for pipe freeze protection:
Use the tables to the right to select the
correct heating cable. Round up to the next
pipe size if your pipe diameter isn’t shown.
The charts assume the lowest ambient
temperature is –20°F (–29°C), with a
minimum of 1/2 in fiberglass insulation or
equivalent. For protection to –40°F (–40°C),
use 1 inch fiberglass insulation or equivalent
fire-resistant insulation.
Add 1 foot to your pipe length for each valve
or spigot on your pipe system. If length of
cable selected is longer than the pipe, spiral
cable evenly along the entire pipe.
Important
All thermal and design information provided here is based upon a “standard installa-
tion”: heating cable fastened to a pipe and thermally insulated. For any other method of
installation or application, consult Pentair Thermal Building Solutions at (800) 542-8936
for design assistance to ensure proper design of electrical distribution and acceptable
pipe temperatures.
