3. ROOF REQUIREMENTS
RoofMate heating cables are designed for use on inclined and flat roofs with
non-combustible shingles (for example, asphalt shingles) or rubber coated, and
on Standing Seam metal roofs that comply with national building codes.
WARNING
Using this product on any other type of roof increases the risk of ice formation,
personal injury, or death from electric shock or fire.
Do not use these heating cables on any other types of roofs, such as:
Roofs with wooden tiles
Composite (tar and gravel) roofs.
If you are not sure that your roof meets these requirements, consult a profes-
sional roofer.
4. ELECTRICAL SYSTEM REQUIREMENTS
The electrical system supplying power to the heating cables must meet the
requirements described below. If you are not sure that these requirements are
met, contact a licensed electrician.
WARNING
Failure to do so may result in injury or death from electric shock or fire.
The heating cable must be connected to an external 120-volt AC outlet which is:
1)
Grounded. The heating cable is equipped with a three-pin plug, which has a
grounding pin. To reduce the risk of fire and electric shock, the cable must
be grounded.
You must connect the plug to a power outlet that is correctly installed and
grounded in accordance with all local requirements and regulations.
It is forbidden to modify the plug supplied with the cable in any way. If it
does not match the outlet, install a suitable outlet by contacting a licensed
electrician.
2)
Protected from ground fault (one of the protection ways is the use of a
ground fault circuit interrupter (GFCI)). As a rule, utility outlets installed
outdoors are equipped with a GFCI system.
If you are not sure that your outlet is protected against ground faults, con-
sult a licensed electrician. An outlet with ground fault protection reduces
the risk of fire or electric shock by stopping the flow of electricity (current)
