1.
Determine the best route for the heating cable on roofs and gutters.
2.
Route the heating cable to avoid mechanical damage from ladders, etc.
3.
Before installing the heating cable, make sure the roof, gutter and
downspouts are free from debris, leaves, pine needles or any combustibles.
4.
Check the maximum exposure temperature rating of all roof, gutter and
downspouts, and select a heater that will not exceed their temperature
ratings.
5.
Use a downspout cable hanger bracket (SSFR15) to support the heating
cable where it enters a downspout to prevent cable from being damaged by
the gutter’s edge. It also can be used as a spacer in wider gutters.
6.
Run heating cable over top of hanger and secure it using UV resistant
cable ties.
7.
Use roof clips for SSFP/SSFR cables (SSFR13 – SSFR14) to attach the
heating cable to the roof.
8.
For roof valleys, measure two thirds of the distance of the way up and
double it. Add this additional length to the overall cable length.
9.
Attach the two warning labels (included with the heating cable). The labels
must be clearly visible on the premises.
