Water Regulations and

Water Regulations and Byelaws These regulations and byelaws ensure a good supply of wholesome water, and that only approved materials, pipes and fi ttings are used to convey water. Building Regulations These are a statutory document and take priority over all other regulations and recommendations. The installation of an unvented hot water system of over 15 litres is classifi ed as a “Controlled Service” and Regulation G3 applies. To meet the requirements of the regulation, installation of an unvented system should be undertaken by a “competent installer”. All installations of unvented hot water storage systems having a capacity of more than 15 litres should be notifi ed to the relevant Local Authority by means of building notice or by the submission of full plans. It is important to note that it is a criminal offence to install an unvented hot water storage system over 15 litres without notifying the Local Authority. Delivery The products are supplied with the following: Unvented water heater (with factory-fi tted T&P) Pressure relief valve set at 6 bar Dielectric junctions Tundish Expansion Vessel Check Valve Pressure reducing Valve x1 x1 x2 x1 x1 x1 x1 Important note: Dielectric junctions must be fitted to all models as they prevent an electrolytic reaction and safeguard against potential aggressive corrosion. If the supplied Dieletric Junctions are not fitted this could void the warranty. INSTALLING NORMS (for the installer) Before installing the heater read these instructions in full. If you are unsure please contact our technical service department (03332407777). The installation must comply with all relevant Water Regulations/Byelaws and Building Regulations. The installer should check with the local water authority for confirmation of the maximum water supply pressure. The appliance should be left packed until it is ready to be installed. When unpacking take care not to damage the temperature and pressure relief valve on the top of the heater. A drain has to be provided for any water discharged through the safety valves. A cold water supply pressure between 1 and 3.5 bar is required (if the mains pressure is above 3.5 bar a pressure reducing valve must be installed). Please note that turning down the stop-cock will reduce flow not pressure. The outlet pressure from the reducing valve (if supplied) is 3.5 bar. A 240 VAC; 3 kW single phase electrical supply is required 6 / EN

This product is a device that must be installed vertically in order to operate correctly. Once installation is complete, and before any water is added or the power supply is connected, use a measuring instrument (i.e. a spirit level) to check that the device has been installed perfectly vertical. The appliance heats water to a temperature below boiling point. It must be linked up to a mains water supply according to the appliance performance levels and capacity. Before connecting the appliance, it is fi rst necessary to: - Check whether the characteristics (please refer to the data plate) meet the customer’s requirements. - Make sure the installation conforms to the IP degree (of protection against the penetration of liquids) of the appliance according to the applicable norms in force. - Read the instructions provided on the packaging label and on the appliance data plate. This appliance was designed to be installed only inside buildings in compliance with the applicable norms in force. Furthermore, installers are requested to keep to the following advice in the presence of: - Damp: do not install the appliance in closed (unventilated) and damp rooms. - Frost: do not install the appliance in areas where the temperature may drop critically and there may be a risk that ice may form. - Sunlight: do not expose the appliance to direct sun rays, even in the presence of windows. - Dust/vapours/gas: do not install the appliance in the presence of particularly dangerous substances such as acidic vapours, dust or those saturated with gas. - Electrical discharges: do not install the appliance directly on electrical supplies that aren’t protected against sudden voltage jumps. In the case of walls made of bricks or perforated blocks, partition walls featuring limited static, or masonry different in some way from those stated, you fi rst need to carry out a preliminary static check of the supporting system. The wall-mounting fastening hooks must be designed to support a weight that is three times higher than the weight of the water heater fi lled with water. Fastening hooks with a diameter of at least 12 mm are recommended. To facilitate maintenance, make sure there is a clearance of at least 50 cm inside the enclosure for access to the electrical equipment. PLUMBING WARNING: Note: If a valve i.e. a non return valve, water meter, pressure reducing valve or any type of valve or fitting that acts as a non return valve is installed on the cold water mains, this will prevent expansion. Therefore it will be necessary to install an expansion vessel (see figure below). Note: If in doubt always install a pressure reducing valve (limited to 3.5bar) and expansion vessel. The outlet from temperature and pressure relief valve/pressure relief valve must not be for any other purpose. Take great care not to allow any swarf into the pipe work or fi ttings, as this might impair the operation of the safety valve(s). The water connection may be carried out as per the following: 7 / EN
