General requirements for roof & gutter
de-icing:
• Gardian is designed to remove melt water,
not accumulated snow.
• Gardian heating cable will not keep snow or
ice from falling off the roof. Snow fences or
snow guards should be used to eliminate
snow movement. For the names of
manufacturers of snow guards or snow
fences, contact Tyco Thermal Controls at
(800) 545-6258.
• Gardian heating cables may be used on:
-Roofs made from all types of standard
roofing materials, including shake, shingle,
rubber, tar, wood, metal, and plastic.
-Gutters made from standard materials,
including metal and plastic.
-Downspouts made from standard materials,
including metal and plastic.
• Do not use an extention cord.
• Do not install the heating cable underneath
any roof covering for roof and gutter de-
icing.
• Install only in accessible locations; do not
install behind walls or where the cable would
be hidden.
• Do not run the heating cable through walls,
ceilings, or floors.
• Connect only to ground-fault protected
outlets that have been installed in accordance
with all prevailing national and local codes
and standards and are protected from rain
and other water.
Note:
Route and secure the heating cable to avoid possible
mechanical damage, such as from ladders, etc.
