SAFETY WARNINGS:

Follow all five of these instructions to prevent
fire or shock:
1. Use the correct heating cable.
• Use only braided versions of Frostex heating cable.
• Earlier versions of Frostex heating cable with no braid
are not compatible.
2. Use the right end seal and plug.
• Seal the heating cable only with the end seal provided;
do not use electrical tape.
• Use the 9800 FlexFit plug contained in this kit. It has
special safety features.
• Use the 9800 FlexFit Plug Kit only with Frostex heating
cable.
3. Do not twist wires together or allow them
to touch each other.
• Do not strip the heating cable. If wires touch, the
nonreplaceable fuse will blow and the system will
not work.
4. Keep the entire Frostex system dry. This
includes the insulation.
If the system gets wet, pipes may freeze.
• Use the system only on insulated residential pipes
carrying water.
• Do not use the system on buried pipes.
• Do not use the system to de-ice roofs or gutters.
• Do not install any part of the heating system where it
would be under water.
• Do not use where water is likely to enter the plug.
5. The blue plastic heating cable and the
metal braid must not be cut or damaged.
• Before you begin, inspect the pipe. File and remove any
sharp edges. Make sure the heating cable crosses only
smooth, nonabrasive surfaces.
• Where the system might be damaged by animals or
objects, protect the complete system with a solid cover,
such as sheet metal or additional pipe insulation.
• Do not use any wire or clamps to attach the heating
cable to the pipe. Instead, use the Frostex 9610
application tape, or equivalent 1/2 in–1 in (13 mm–25
mm) tape, or plastic cable ties.
• Inspect the heating cable periodically for damage. If you
discover broken braid or other damage, immediately
disconnect the system and replace the heating cable.
Do not splice or repair a damaged heating cable. You
must replace any damaged insulation or waterproof
covering.
6. Do not install Frostex heating cable close
to flammable materials, liquids, or fumes.
• Use only 1/2 in (13 mm) or thicker fire-retardant and
waterproof pipe insulation, in accordance with Table 1
or 2.

GENERAL INSTRUCTIONS

• Observe the safety warnings on page 1. Follow the
installation steps (pages 2–7) in the exact order given.
• To ensure the plug is properly connected, do not assemble
at temperatures below 0°F (–18°C).
• The Frostex system can be left plugged in all year, however
you will save energy by unplugging the system when there
is no risk of freezing.
• Use a properly grounded, 3-prong, 120-V outlet. If you
are not sure if your outlet is properly grounded, call a
professional service person.
• In manufactured housing installations, use the electrical
receptacle on the underside of the home. Do not use an
extension cord or there may be danger of fire or shock.
Using an extension cord is not in compliance with national
electrical codes.
• Frostex heating cable may be used on metal or plastic
pipes and tubing. Do not install on garden hoses or in
applications with tubing that is flexed frequently.
• Exposure to temperatures above 150°F (65°C) will shorten
the life of your Frostex heating cable. Before installing the
heating cable on hot water pipes, set the water heater
thermostat below 150°F (65°C), low to medium on most
thermostats.
• Remove any old heating tapes and insulation before you
install the Frostex heating cable.
• Do not use more than 50 feet (15 meters) of Frostex
heating cable with each 9800 FlexFit plug. Longer lengths
will blow the nonreplaceable fuse in the plug.
• The homeowner will need to keep these instructions for
future reference. It contains important safety warnings and
maintenance information.
• If you have any difficulty installing the system, please
contact nVent for information at (800) 545-6258, or call a
professional service person for help.
• Remove the clear label that covers the test and reset
buttons after installation.

INSTALLATION INSTRUCTIONS

Step 1.
Determine the length of heating
cable you need
1A. Collect the necessary information
You will need to know the following:
• Type of pipe (plastic or metal).
• Length and diameter of pipe.
• Lowest expected air temperature (disregard
windchill).
• Number of valves and spigots (requires additional
heating cable).
• If there is a crock (typically used for manufactured
housing applications).
1B. Determine the amount of Frostex
heating cable you will need
How to use the tables:
• Decide on the lowest temperature you can expect in
your area, down to –40°F (–40°C).
• Measure the diameter of your pipe in inches.
• Using Table 1 or 2 depending on pipe material,
determine how many straight runs of Frostex heating
cable required to protect the pipe. One run is equal to
the length of the pipe.
• To minimize the amount of heating cable required,
select the optimal insulation thickness from Table 1
or Table 2.
