Roof, Gutter & Downspout Requirements; Electrical Requirements - EasyHeat ADKS Serie Guia Del Usuario

III. ROOF, GUTTER & DOWNSPOUT
REQUIREMENTS
This kit is only designed for use on:
• inclined roofs. An inclined roof is one where the water is expected to
flow off the roof edge.
• roofs with noncombustible tab shingles (such as asphalt shingles) that
meet national building codes.
• metal or plastic gutters/downspouts.
WARNING
Use of this kit on any other type of roof, gutter or downspout
increases the risk of ice dam formation or injury or death from
electric shock or fire.
Do not use this kit on any other type of roof, gutter and downspout, including:
• Roofs with wooden shingles.
• Rubber or rubber membrane roofs.
• Composite (tar and gravel) roofs.
• Wooden gutters or downspouts.
• Flat roofs.
• Slate, stone or ceramic and metal roofs. These types of roofs re-
quire special consideration. Contact Easy Heat for more information
toll-free at 800/562-6587.
If you are unsure if your roof, gutters, and downspouts meet these require-
ments, call a professional roofing contractor.
IV. ELECTRICAL REQUIREMENTS
There are several requirements for the electrical system that supplies power to
this deicing cable. Check with your local electrical inspector or a licensed elec-
trician if you are unsure about the requirements listed below or what you may
need to do in order to meet all applicable electrical codes and ordinances.
WARNING
Failure to meet these electrical system requirements
may result in ice dam formation or injury or death from electric
shock or fire.
This cable must be plugged into a 120 volt A/C outdoor receptacle that:
• Is grounded. This cable is equipped with a three-prong plug that has a
grounding prong. To reduce the risk of fire and electric shock, this cable
must be grounded. To do this, the plug must be plugged into an outlet that
is properly installed and grounded in accordance with all local electrical
codes and ordinances.
Do not modify the plug provided with the cable. If it will not fit the outlet,
have a proper outlet installed by a licensed electrician.

• Is ground-fault protected. A ground-fault protected receptacle reduces
the risk of fire or electric shock by stopping the flow of electricity (current)
when it senses that current is flowing through something other than the
cable (for example, a person or downspout). This unintended current:
• can be caused by a damaged cable,
• may not be large enough to trip a circuit breaker,
• can lead to overheating of the cable, which can result in fire, and
• may result in electrocution due to exposed electrical parts.
One type of ground-fault protection is a ground-fault circuit-interrupter
(GFCI). Some, but not all, outdoor receptacles are equipped with a
GFCI.
If you are not sure if your receptacle has ground-fault protection, check
with your local electrical inspector or a licensed electrician, or use the
Easy Heat Heating Cable Protector (HCP1) (sold separately). The Easy
Heat Heating Cable Protector (HCP1) is a ground-fault protection device
that is intended primarily to protect against fire. The HCP1 also provides
some protection against electric shock and electrocution, but it does not
reduce the risk as much as a GFCI.
• Is on a circuit that has an appropriate current (amp) rating. Do
not use this cable on a circuit whose circuit breaker or fuse is rated at
more than 20 amps. Limiting the circuit to a maximum of 20 amps will
reduce the risk of fire and electric shock if the cable becomes damaged.
While a 20 amp circuit is the maximum allowed, you also need to check
that the circuit can supply enough current without being overloaded.
Overloading a circuit can lead to a tripped breaker or a blown fuse. To
avoid overloading the circuit, do not use more than 80% of the circuit's
rated capacity (for example, do not load a 20 amp circuit more than 16
amps, and do not load a 15 amp circuit above 12 amps).
See Table 1 below for the current needed for your cable length. If you do
not have a circuit with an appropriate rating, contact a licensed electrician.
