For straight tracing, install the heating cable on a lower half of the pipe; for example, in the 4
o'clock or 8 o'clock position.
Be sure to install the additional heating cable required for valves, flanges, etc. as shown in
Figures 1 and 2.
When the design calls for spiraling, begin by suspending a loop every 10 feet as shown in
Figure 2. To determine the loop length, divide the SpeedTrace Extreme heating cable length
by your pipe length and multiply by 10. For example, if you are using a 50 ft. SpeedTrace
Extreme heating cable on a 40 foot pipe, leave a 12 foot loop of heating cable at every 10
foot section of pipe. Grasp the loop in its center and wrap it around the pipe. Even out the
distance between spirals by sliding the wraps along the pipe. Use recommended fiberglass
or aluminum adhesive tape to secure the center of the loop to the pipe.
Fasten SpeedTrace Extreme heating cable to the pipe at 1- foot intervals using PSAT36A
fiberglass tape or AAT260 aluminum tape. Do not use vinyl electrical tape, duct tape, metal
bands, or wire.
If excess cable remains at the end of the pipe, double it back along the pipe.
3.
Check the installation
Prior to installing thermal insulation make sure the heating cable is free of mechanical
damage (from cuts, clamps, etc.) and thermal damage (from solder, overheating etc.).
4.
Install thermal insulation
A reliable SpeedTrace Extreme heating cable system depends on properly installed and dry,
weatherproofed thermal insulation like the INSUL-LOCK DS Flexible Closed Cell Pipe
Insulation.
Ensure that at least ½" of preformed foam or equivalent thermal insulation is used and that
all piping, including valves, joints, and wall penetrations, has been fully insulated as shown
in Figure 3.
For protection to -20°F (-29°C), use 1" (25mm) thick insulation.
Install the insulation on the piping as soon as possible to minimize the potential for
mechanical damage after installation.
Be sure the SpeedTrace Extreme heating cable label is visible on the outside of the thermal
insulation.

5.
Finishing the installation
To prevent damage to the heating cable or cord, secure the power cord (cold lead) with a
plastic cable tie, glass cloth tape, or duct tape as shown in Figure 4.
Electrical tracing labels indicating the presence of electric pipe heating cable are included
with the heating cable. Attach the supplied "Electrical Tracing" labels on the outer surface of
the pipe insulation at an interval of one label for every 10 ft (3 m) of pipe to indicate the
presence of the SpeedTrace Extreme heating cable.
6.
Starting the system
®
BriskHeat
recommends that the system be tested per the "Cable testing and maintenance"
section below.
Plug the heating cable into a ground-fault protected outlet.
Check the circuit breaker to verify power to the cable.
Standing water in the pipe should feel warm within an hour.
7.
Ground fault protection
®
BriskHeat
and national electrical codes require ground-fault equipment protection on each
heating cable branch circuit.
To reduce the risk of fire caused by damage or improper installation, circuit breakers or
equivalent, with a 30-mA trip level, should be used. Alternative designs providing
comparable levels of ground-fault protection may also be acceptable. For technical
assistance, please contact BriskHeat at 1-800-848-7673 (U.S. / Canada), or
1-614-294-3376 (worldwide).
WARNING
Conditions of maintenance and supervision ensure that only qualified persons service the
installed systems.
Continued circuit operation is necessary for safe operation of equipment.

CABLE TESTING AND MAINTENANCE

Using a 2500-Vdc megohmmeter, check the insulation resistance between both of the
rectangular (power) prongs on the plug and the round (ground) prong after installing the
heating cable. Minimum reading should be 1000 megohms.
Record the original values for each circuit, and compare subsequent readings taken during
regular maintenance schedules to the original values.
If the readings fall below 1000 megohms, replace the SpeedTrace Extreme heating cable
with a new unit. Do not attempt to repair the unit.
