Fig. 1 (Note this system

Fig. 1 (Note this system is not suitable for model 30L) 1) Using the feed pipe to accommodate expansion (Schedule 2, Section 6: Paragraph 15 of the Water Supply (Water Fittings) Regulations 1999 and the Water Byelaws 2000, Scotland) (Fig. 1). Do not fit any stop cocks or isolating valves within the distance required for expansion. If a pressure reducing valve is needed, due to a mains pressure of over 3.5 bar, an expansion control kit must be fitted regardless of expansion pipework installed. The expansion distances quoted are for 15mm pipes and can be approximately halved for 22mm pipes. 2) Using a set of expansion controls (Fig. 2 & 3). Fig. 2 (Models 10L/15L) 12

Fig. 3 (Models 30L) The tundish must be installed away from electrical devices. The model 30L is covered under the Building Regulations and therefore it is not possible to accommodate the expansion water within the system pipe work and consequently a set of expansion controls must be installed. Note: The discharge from relief valves must be made in a safe and conspicuous manner; therefore a tundish (Kit C) is available for 10 and 15 litre units if required. Please note that in all cases the dielectric junctions must be connected to the heater before any other connection is made (these prevent an electrolytic reaction). Only the use of copper pipe is recommended for connection to the heater. If any other material is used it must be able to withstand 90°C at 7 bar pressure for long periods. No valve must be fitted between the expansion/pressure relief valve and the water heater. All other required safety components to install the model 30L are supplied as a kit with the appliance: 15mm pressure reducing valve set at 3.5bar. Expansion vessel (charge pressure set at 3.5bar)" c) DISCHARGE PIPE WORK NOTE: The following guidelines refer to Building Regulation G3. It is good practice to follow these guidlines for all relief valve discharge pipe work. 1) The tundish must be vertical and fitted within 600 mm of the temperature & pressure relief valve and must be located with the cylinder. The tundish must also be in a position visible to the occupants, and positioned away from any electrical devices. The discharge pipe from the tundish should terminate in a safe place where there is no risk to persons in the vicinity of the discharge and to be of metal. 2) Discharge pipes from the temperature & pressure relief and pressure relief valve may be joined together. 13
