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.
