Scheduling

The installation of the electric heat tracing needs to be coordinated with the piping, insulation, electrical and instrument groups. It should
begin only after the majority of mechanical construction is complete. Pressure testing of the pipe and installation of the instruments
should be complete prior to the start of the heating cable installation.

Pre-Installation Check

Walk the piping system and plan the routing of the heating cable. Use this check to verify completion of instrumentation and mechanical
work. All coatings (paint, etc.) must be dry before attempting the heating cable installation. Minimum installation temperature -40°F
(-40°C)

Heater Handling


Use a reel holder to roll out the heating cable.

Keep the cable strung loosely, but close to the pipe being traced. This will avoid interference with supports and other equipment.

Leave an extra 305-457mm (12-18") of heating cable at all power connections, tee splices and end seal connections to facilitate
easy working of the connections.

ADDITIONAL HEATING CABLE IS REQUIRED ON VALVES, PIPE SUPPORTS AND OTHER EQUIMENT. See the installation
detail section for exact lengths and method of installation.

When handling the heating cable, avoid pulling it over or installing against sharp edges.

Do not kink or crush the cable, including walking on it or driving over it with equipment.

Do not exceed minimum bending radius of 0.5" (12mm) at 68°F (20°C) during installation. Colder temperatures will increase the
minimum bend radius. Use caution to avoid exceeding a safe bend radius during cold temperature installations.

Heating Cable Location

The heating cable may be installed in either straight runs or spiraled around the pipe. Spiraling is generally used when a limited number
of cable types are available.

Straight Tracing

When straight tracing is used, install the heating cable on the lower quadrant of the pipe. This helps prevent physical damage to the
heating cable from falling objects and being walked on, and promotes optional thermal transfer to materials inside the pipe.

Spiraling

Spiraling increases the length of heating cable installed per foot of pipe. For spiraling application assistance, contact BriskHeat
factory.

Attachment

For regular installations, the heating cable may be attached with fiberglass tape. Plastic wire ties may also be used provided the plastic
has a maximum temperature rating equal to or better than the system requirements. The cable should fit snugly against the pipe and be
secured at one 305mm (12") intervals, as shown in Figure 4.

Notes:
1. To prevent possible damage to the heating cable, do not fasten with metal straps, wire, vinyl electrical tape or duct tape.
2. Aluminum foil tape should only be used if specified by design. The foil is most often used on plastic pipe to offset the insulate effect
of the plastic. See Figure 5 above.

Cutting the Heating Cable

Do not cut the cable until it is attached to the pipe. Confirm the allowances for terminations, connections and heat sinks (valves,
support, etc.) before cutting the cable. Heating cable power is not affected by cutting to length. Protect all heating cable ends from
moisture or mechanical damage if exposed for long periods of time.

Installation Details

Heating cables should be applied in a manner to facilitate the easy removal of valves and small in-line devices without the removal of
excessive thermal insulation or having to cut the heating cable. The best way to accomplish this is to loop the cable. The amount of
heating cable installed on each valve, hanger, etc. varies with the pipe size and type of device. For installation and application
assistance, contact BriskHeat factory.
