Page 10: Installation - Plumbing
Installation: Plumbing Water supply requirements The Fusion E10 Combi operates at 3 bar (controlled by the inlet control set) and is capable of delivering over 50 litres per minute. The high quality inlet control set has been designed to make the most of the flow rates available, however the performance of any unvented system is only as good as the mains water supply to the unit. - Page 11 Installation: Plumbing/ Cont.. Balanced cold connection If the system includes showers, bidets or monobloc taps, then a balanced cold supply is necessary. Do not use monobloc mixer tap or showers if the balanced cold connection is not used. Outlets of this type can back-pressurise the unit and result in discharge. A 22mm balanced cold mains outlet can be found on the control set supplied, (see diagram below) Use the balanced cold mains outlet from the inlet control set (as shown in the illustration) to...

Page 12: Installation - Discharge Arrangement
Installation: discharge arrangement The above diagram is of a typical discharge pipe arrangement. (extract from Building Regulation G3) Note: The discharge will consist of scalding water and steam. Asphalt, roofing felt and non- metallic rainwater goods may be damaged by such discharges. Note: It is not acceptable to discharge straight into a soil pipe. - Page 13 Installation: discharge arrangement /cont C) Be installed with a continuous fall. D) It is preferable for the discharge to be visible at both the tundish and the final point of discharge but where this is not possible or practically difficult there should be clear visibility at one or other of these locations.
