6. Cable layout must insure that both ends of cable end in the

junction box (see example 1). If there is not enough cable
to do so following the layout drawing, adjust the layout
by shortening every other cable towards the center from
the corners and ends slightly (see example 2). Contact
Thermon prior to completion of installation should there
be any discrepancies between the layout drawings and
actual field conditions.

7. Where expansion joints must be crossed, KSR-EJK expan-

sion joint kits are to be installed as shown below.

8. Attach cable with nylon tie straps on approximately 12"

centers such that installed cable will be between 2" and 3"
below the snow melting surface of the concrete.

DO NOT Use metal wire to secure heating cable
to rebar or steel mesh - electrical
hazard and short circuits could result!

Terminating the Heating Cable . . .

1. Upon completion of the cable layout recheck the spacing

and ensure agreement with the specific project layout
drawings. Check circuit length to insure length does not
exceed maximum length provided in Design Guide.

2. Terminate the ends of the snow melting cable using a

KSR-CFK circuit fabrication kit and the accompanying
instruction sheets.
