5.1Filling the appliance
5.1.1Filling unvented installations
To fill the appliance, proceed as follows:
1.Open the stop valve (11) in the hot water pipe and, if present, the stop valves
(4)for the circulation pump (6).
2.Close the drain valve (9).
3.Open the nearest hot water
4.Open the stop valve (4) on the cold water side (A) so that cold water flows into the appliance.
5.Completely fill the appliance. When a full water jet flows from the nearest
6.Bleed the entire installation of air, for example by opening all
7.The appliance is now under water supply pressure. There should be no water coming out of the expansion valve (15), nor the T&P valve (3). If this does happen, the cause might be:
- The water supply pressure is greater than the specified 8 bar. Rectify this by fitting a pressure reducing valve (1).
- The expansion valve in the protected cold supply setup is defective or incorrectly fitted.
