5.1 Filling unvented
installations
To fill the water heater, 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 draw-off point (14).
4. Open the stop valve (4) on the cold water side (A) so that cold water flows
into the water heater.
5. Completely fill the water heater. When a full water jet flows from the nearest
draw-off point, the water heater is full.
6. Bleed the entire installation of air, for example by opening all draw-off points.
7. The water heater is now under water supply pressure. There should now be
no water coming out of the inlet combination expansion valve or (if used) out
of the T&P valve (3). If there is, the cause might be:
- The water supply pressure is greater than the specified
value (3.4.2 "
General and electrical specifications").
Rectify this by fitting a pressure reducing valve (1).
- The expansion valve in the protected cold supply set-up is defective or
incorrectly fitted.
