Page 11: Installation Instructions
Installation Instructions Before installing the heater read these instructions in full. If you are unsure please contact our technical department 0844 372 7766. The installation must comply with all relevant Water and Building Regulations. The installer should check with the local water authority for confirmation of the maximum water supply pressure. - Page 12 Accommodation of the expansion in supply pipe work (diagrams 2 & 3). diagram 2 MW 10/15 diagram 3 EW 10/15 Do not fit any stop-cocks or non-return valves within the distance required for expansion. The distances quoted are for 15 mm pipe these can be approximately halved for 22 mm pipe to shorten the distance required for expansion.
- Page 13 Accommodation of expansion in an expansion vessel (diagrams 4 & 5). diagram 4 MW 10/15 diagram 5 EW 10/15 Using a pressure reducing valve (set at 3.5 bar), a non-return valve and expansion vessel charged to 3.5 bar, the expansion is accommodated in the vessel.
- Page 14 c) Discharge pipe work NOTE: The following guidelines refer to Building Regulation G3. This regulation only applies to an unvented system over 15 litres. It is good practice to adopt the same principles for the EW and MW range. 1) The tundish must be vertical and fitted within 500 mm of the temperature & pressure relief valve and must be located with the water heater.
- Page 15 iv) Where a single pipe serves a number of discharges, such as in blocks of flats, the number served should be limited to not more than 6 systems so that any installation can be traced reasonably easily. The single common discharge pipe should be at least one pipe size large than the largest individual discharge pipe to be connected.

Once the element is free from the water container the anode may then be inspected and removed if necessary. When reassembling the cover make sure that the regulation knob is coupled with the thermostat. Fault finding Pressure and temperature valve dripping/running all the time. Cause: Thermal cut-out and thermostat have failed (this is only the case if the water being discharged is near to boiling). -
