“Multiblock T-RTL” Connection fittings for the combination of radiator and surface heating systems Technical information Das Qualitätsmanagementsystem von Oventrop ist gemäß DIN-EN-ISO 9001 zertifiziert. Tender specification: Oventrop connection fitting “Multiblock T-RTL” for the combination of radiator and surface heating systems for room temperature control and limitation of return temperature. With presettable valve insert, radiator isolating facility and integrated return temperature limiter (RTL). For radiators with a distance of 50 mm between the pipe centres, radiator connection soft sealing. Body made of nickel plated brass, stem of the valve insert made of stainless steel with double O-ring seal. Technical data as “Series AV 6”. G 3⁄4 pipework connections according to DIN EN 16313 (cone “Euro”) for Oventrop compression fittings (alternatively, the compression fittings of other manufacturers – except for composition pipe “Copipe” – which are suitable for the connection to male thread G 3⁄4 according to DIN EN 16313 (cone “Euro”) may also be used). “Multiblock T-RTL” White or chrome plated design covers made of plastic available as accessories. Technical data: Operating temperature ts: Max. operating pressure ps: Recommended differential pressure range: 30 up to 200 mbar Control range return temperature: 10 °C up to 40 °C 2 °C up to 70 °C 10 bar (PN 10) Models: “Multiblock T-RTL” for radiators with: Item no.: G 3⁄4 male thread according to DIN EN 16313 Rp 1⁄2 female thread Design cover white chrome plated 1184016 1184086 Design cover 1184087 1184077 Function: The connecting fitting for two pipe heating systems is a combination consisting of a presettable thermostatic valve, an isolating fitting and a return temperature limiter (RTL). Room temperature control is carried out by the thermostatic valve with mounted thermostat in combination with a radiator. Surface temperature balance is carried out independent of the thermostatic valve by limiting the return temperature via the integrated return temperature limiter. Advantages: Oventrop connection fitting “Multiblock T-RTL” for the connection to all radiators with a distance of 50 mm between the pipe centres – for separate control of radiator and surface heating with one fitting – for isolation – presettable flow rate – adjustable surface heating return temperature Application: Two pipe central heating systems, max. operating pressure 10 bar (PN 10), max. flow temperature 70 °C irrespective of the type of heat source, for heating water according to VDI 2035. Installation can be carried out with any standard pipe material. Oventrop offers suitable compression fittings for copper, stainless steel and plastic pipes as well as the composition pipe “Copipe”. The corresponding installation instructions are to be observed. 2014 Oventrop System illustration 1 “Multiblock T-RTL” Connection fittings for the combination of radiator and surface heating systems Installation: >120 Preparations: The position of the radiator and fitting have to be determined with due consideration of the specifications of the radiator manufacturer. The direction of flow must conform to the arrow on the valve body. Pipework In new buildings, the pipework for the supply and return connection of the heating circuit (middle connections of the fitting) is laid during the building shell phase. Suitable wall channels for the heating circuit and surface temperature balance have to be created for this purpose (see illustr. “Illustrated section, heating circuit connection” and “Wall view, heating circuit connection”). During pipework installation please observe that pipes must run in parallel. >200 Brickwork Insulation Upper edge finished floor The connection pipes laid into the wall have to be insulated according to the Energy Saving Directive. This will also facilitate the connection of the fitting. Laying of the connection pipes for surface temperature balance is only carried out after wall plastering has been completed. For radiators with female thread Rp 1⁄ 2, use enclosed selfsealing nipples and screw them tightly into the connection nipples of the radiator (only applies for item no. 1184086). For the connection of copper, precision steel, stainless steel and plastic pipes as well as the composition pipe “Copipe”, the Oventrop compression fittings are to be used (alternatively the compression fittings of other manufacturers – except for the composition pipe “Copipe” – which are suitable for the connection to male thread G 3⁄4 according to DIN EN 16313). Installation of the surface circuit: When designing the floor as surface heating, the construction regarding thermal and sound insulation, has to comply with the valid rules, standards and regulations. Once the insulation has been applied, the supply pipe of the surface circuit is connected to the connection “FV” and the return pipe to the connection “FR” of the “Multiblock T-RTL” (see illustr. “Wall view, surface temperature balance”). The surface heating circuit has to be laid in a spiral pattern in order to achieve a constant temperature distribution. Installation of the surface heating circuit can be carried out with any standard pipe material. Oventrop offers suitable compression fittings for copper, stainless steel and plastic pipes as well as the composition pipe “Copipe”. The corresponding installation instructions are to be observed. >105 >125 50 50 70 Brickwork >30 Screw “Multiblock T-RTL” to the radiator tension-free (torque 20-30 Nm) and connect to the pipework of the heating circuit by use of compression fittings.
