Fig. 2 The tundish must be installed away from electrical devices. (Models 10/15L)
The water connection may be carried out as per the following.
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).
