Gutters and drains
For standard gutters with a 33 cm perimeter, we most often use the FTC 30 heating cable led in the gulley and subsequently drain only once. The heating cable usually starts with the power supply end on the side of the gutter without the drain. The cable can be connected with the FX/KIT/C kit straight to the box (e.g. FX/JB) or it can be extended by a power flex and led to the nearest connecting box. The cable is then led through the gutter and hanged into the drain using the FX/CRT stainless steel holder. It usually isn´t necessary to attach the heating cable to the drain in any other way. It can be occasionally glued with silicone putty. The blind end is usually at the end of the drain, terminated by a shrink sleeve, that is a part of the FX/KIT/C kit. The blind end is either pulled into a non-freezing depth of the sewage, or it is ended by a loop at the outfall of the drain. With multiple drains or branched gutters, the heating cable can be branched by an FX/JB box in an overall length of 100m.
Valleys
The necessary output for heating of valleys and valley gutters is around 200 W/m2. If using the FTC 30 or KYX cables, then the distance between cables is approximately 15 cm. The heating cables are usually attached by plastic struts. In the case of two cables, it is possible to ensure the distance between them by spacers made from the CY6 wire.
Roof edges
Usually we heat a 50 cm wide strip below the snow arresters with a heating output around 200 W/m2. The heating cable is installed according to the picture in a wavy or zigzag line. Attachment is chosen according to the type of a roof and roofing. For the firm fixation of the heating cable to the roof edge, it is possible to use silicone putty, plastic, sheet metal or wire clamps or a combination of these methods.
