This vertical roof drain, featuring a bitumen membrane collar (500), an insulated body, a 180 debris guard, and self-regulating heating (10-30W/230V), is used for collecting rainwater from non-accessible terraces and directing it to the building’s drainage system. It is recommended for waterproofing with bitumen membranes. -Material: PP. -Installation height: 10 cm. -Debris guard: 145 mm. -Components: drain body, stainless steel flange and bitumen membrane collar, flat debris guard, domed debris guard, self-regulating electric heating element. -Flow rate: 14 l/s. -Complies with EN 1253. The product is supplied with an anti-contamination protective cap for installation. Installation opening diameter: 255 mm. Connection to the building’s drainage system is made via a socket-gasket system for PP pipes, and by welding for HDPE pipes, using connectors: 46012110110 (for 110), 46012125125 (for 125), 46012075075 (for 75). It is recommended to perform at least one cleaning before the start of the season, or as needed for optimal drain operation. Recommendations for installing heated roof drains: -The heating coil connects to a 230V AC electrical conductor. The conductor length is 0.8 m. Connection is made via an electrical junction box placed on the support layer, underneath it, considering particular situations and the permitted conductor length. -An automatic circuit breaker with a type C tripping curve, 30mA, 100ms with 10A short-circuit protection, must be installed. Power consumption based on outdoor temperatures is: +10°C – 5.55W, +5°C – 9.25W, -10°C – 12.95W. The self-regulating heating coil is sensitive to outdoor temperatures when powered. It will heat even in warm seasons. Therefore, an outdoor thermostat is very useful for regulation. Manual heating control will be affected by human factors, especially during summer when heating should be turned off and frequent rains occur. Thermostat settings will depend on specific climatic conditions and building location. Typically, +5°C is considered the maximum temperature for contact closure. When connecting multiple drains to larger heating systems, for example, when combined with gutter heating, using thermostats with multiple sensors is recommended. The heating coil is tested according to VDE 0721 – 1/3.78 and VDE1008. Heating projects, operating manuals, and electrical connections must only be carried out by authorized companies. Electrical connections and installation methods for heated drains must comply with current local laws and regulations. It is recommended that before connecting the conductors in the junction box, a test of the heating circuit be performed, including measuring the resistance between the phase and neutral of the heating coil and recording this in the acceptance protocols (and building logbook).
