ELEKTRA SelfTec PRO 10, Руководство по установке

Страница: 14 / 108

The values given above refer to a gutter of the Ø100-125 mm diameter.
Gutters of larger diameters require application of the 20 W/m higher heat
output.
Flat roofs, or when roof snow barriers are installed, which would cause
snow deposition, require increase of the given values with approx. 15%.
Selection of the optimal power range depends from the climate zone the
building is located in.
Heating gutters and downpipes of the width (diameter) 150 mm installed in
a building located in the climate zone with mild winters requires single-led
®
installation of ELEKTRA SelfTec PRO 20 or 33 heating cable. For wider
gutters (of a diameter larger than 150 mm), double-led installation of
®
ELEKTRA SelfTec PRO 20 or 33 heating cable is recommended.
In regions that receive large amounts of snowfall, it is recommended to
additionally heat the roof edge adjacent to the heated gutter (suggested
width of the heated roof surface is approx. 500 mm).
Note:
If the downpipe water is led directly to a drainage channel, it is
necessary also to heat the downpipe segment from the ground level
to the frost penetration depth.
