ATTACHING CABLE TO PIPE
1.Prior to installing the cable, be sure all piping is dry, and any sharp surfaces are removed.
2.Attach heating cable to pipe with straight, spiraling or multiple tracing.
3.If the heating cable is the same length as the pipe, run it straight along the bottom of the pipe. If two cables are
required, position them in the 4 and 8 o'clock positions. If three cables are required, position them in the 11 o'clock or
1 o'clock positions and 4 o'clock and 8 o'clock positions.
4.If the cable is less than double the pipe length, spiral the cable over the length of pipe.
5.Any excess cable remaining at the end of the pipe can be doubled back along the pipe.
6.Be sure to include any additional heating cable required for valves, spigots, etc.
7.Secure the cable to the pipe with JSR0301/JSR0302 fiberglass application tape or nylon cable ties. Do not use
vinyl tape, metallic products or wire.
INSTALLING THERMAL INSULATION
1.Before insulating, inspect the cable to ensure that it is free of mechanical damage, such as gouges or cuts, etc.
2.Cover the pipe, cables, connections, valves with at least 1/2" (12.7mm) thick fiberglass insulation or equivalent. DO
NOT leave the cables exposed.
3.Use fire-resistant materials such as fiberglass wrap. Make sure the insulation is waterproofed (with polyethylene or
other vapor barriers) in areas where water may come in contact with the insulation.
4.Place the two warning labels on the outer surface of the pipe insulation where clearly visible and at suitable
locations to indicate the presence of electric heating cable.
5.After installation is complete, turn the circuit breaker on to give power to the cable. Standing water in the pipe
should feel warm within one hour.
MAINTENANCE CHECKS
1.Only qualified persons should service or install the system.
2.Check yearly for any damage to the heating cable and check any ground fault protection device for proper
operation. If any damage to cable is found, DO NOT operate until it is replaced.
Heating Cables for Roofs, Gutters and Downspouts
CHOOSING A CABLE
1.Determine the total length of cable needed by adding the total roof edge length (ft.) x feet of heating cable per foot
of roof edge, see Table 1 below, the total gutter length (ft.), and the total downspout length (ft. plus 1).
NOTE: The roof edge length (ft.) x feet of heating cable required per foot of roof edge equals the Total roof edge
cable length required.
2.For shingle roofs, add 1 foot of heating cable for each foot of gutter.
3.Add 1 foot of heating cable per foot of downspout.
4.When the downspout is between the gutter ends, double the length of the downspout to determine the length of
cable needed.
