Installation and Operation Instructions

2.4 Installers
Installation of the heating cable must be carried out by persons authorized to
carry out electrical work.
2.5 When to Install RoofMate
The heating cable should be installed when there is no ice or snow on the roof.
Do not use the heating cable to melt the snow and ice that has already formed
on your roof. If snow and ice are already on the roof, consult a professional
roofer for help. Heating cables should only be installed after the ice and snow
have melted and/or are removed. The temperature when installing the cable
should be between 32 and 80°F (0 to 27°C).
2.6 Where to Install RoofMate
The heating cable should be installed on areas of the roof where ice deposits,
including icicles, can form. Depending on the influence of the sun, the prevail-
ing wind direction and the shape of the roof, cables can be installed both over
the entire roof area, and in individual sections.
2.7. Determining Necessary Cable Length
An accurate estimate of the cable length required is very important as it is not
possible to alter or modify a cables length. The cable should be installed on
the areas of the roof where ice forms. This can be the entire edge of the roof or
in individual sections. The cable must also be installed in any nearby gutters,
drainage pipes and/or valleys.
If you need to install a cable on a roof with gutters, drainage pipes, valleys and/
or attic windows, follow the instructions “A. For Typical Applications.”
If you need to install the cable only in the gutters and drainage pipes, follow the
instructions “B. For Installation in a Gutter and Drain Only.”
