Installation requirements 7Vaillant Vantage 120/150/200 177.3 Secondary SystemTo achieve optimum distribution of the water supply it isimportant that the water system pipework andterminal fittings are correctly sized and balanced. Theteed-off supply to the bath outlet should be in 15 mmpipework. The tee-offs to sinks and basins should be in10 mm pipework. Terminal fittings should be suitable formains pressure operation and taps should be of theaerated type to prevent splashing.Some designs of terminal fittings may allow excessiveflow rates resulting in user inconvenience and starvationof other outlets. In these circumstances provide a valvein the supply to that terminal fitting in order that theflow rate can be regulated.If the VANTAGE is being installed to existing pipeworkwith a 22 mm run to the bath terminal fittings and/or 15mm to sinks/basins, an adjustable valve should be fittedin the supply to each outlet: By adjustment of these val-ves, flow rates to fittings can be regulated to achievecorrect system balancing.If the water capacity of the additional secondary pipe-work exceeds20 litres (VANTAGE 120 or 200) or10 litres (VANTAGE 150) anadditional expansion vessel may be required.Pipe capacities for copper tube are:15 mm 0.13 l/m22 mm 0.38 l/m28 mm 0.55 l/mThe cylinder may be drained completely for maintenan-ce works via the drain valve (E, fig. 6) after first turningoff the water supply to the cylinder and opening the hotdraw off taps. Adequate access to the drain valve musttherefore be available.Fig. 740408 bar*4 bar*3 bar*2 bar*1 bar*8 bar*4 bar*3 bar*2 bar*1 bar*30302020flow available (litres/min) at entry to systemMixed water @ 40 °C, mixed from60 % hot water @ 60 °C and40 % cold water @ 10 °CNotes:1) flow rates shown apply to situations where the supply is capable of supplying an adequate dynamic pressure.2) the graph represents the results of tests carried out by the BBA and Vaillant.3) where static water pressures are less than 1 bar, consult Vaillant Ltd.* static supply pressure of incoming water supply.flow out (litres/min) of the system10100404030302020flow available (litres/min) at entry to systemflow out (litres/min) of the system10100Flow rates from VANTAGE, hot 60 °C.Flow rates from VANTAGE, hot cold mixed.VIH 364/1
