Page 12: Installation
6 INSTALLATION 6.1 Cylinder Location The unit can be located in any convenient, frost-free, indoor location. As it is connected directly to the mains water supply it is equally efficient on any floor – ground, first, second, etc. The unit can be fitted into a conventional airing cupboard and does not require any additional insulation or ventilation. -
Page 13: Primary, Renewable & Tertiary Circuits
6.3 Primary, Renewable & Tertiary Circuits The working pressure and temperature for all heat exchanger coils is given in Table 1. All connection to the cylinder must be made using compression fittings. 6.3.1 Safety thermostat Each heat exchanger coil has an associated combined control & safety thermostat. The system controls must be wired in such a manner as to cut off the flow of heat to the cylinder in the event of overheating in order to comply with Building Regulations and to ensure a safe installation. -

Page 15: Discharge Pipework
6.8 Discharge Pipework The following is an extract from Section G3 of the Building Regulations for England and Wales and provides the most up-to-date guidance on the requirements for discharge pipework. Refer also to Figure 8. Discharge Pipe D1 3.50 Safety devices should discharge either directly or by way of a manifold via a short length of metal pipe (D1) to a tundish. - Page 16 Note: An alternative approach for sizing discharge pipes would be to follow Annex D, Section D.2 of BS 6700:2006 + A1:2009. 3.59 Where a single common discharge pipe serves more than one system, it should be at least one pipe size larger than the largest individual discharge pipe (D2) to be connected. 3.60 The discharge pipe should not be connected to a soil discharge stack unless it can be demonstrated that the soil discharge stack is capable of safely withstanding temperatures of the water discharged, in which case, it should:...

6.9 Worked Example The example below is for a G½” temperature relief valve with a discharge pipe (D2) having 4 no. elbows and a length of 7m from the tundish to the point of discharge. The calculation shows that 22mm pipe would be unacceptable. UNACCEPTABLE ACCEPTABLE Discharge pipe (D2) run in 22mm copper:... -
