4.8.2 Filling the hot water heat exchanger
Open the shutoff valve for the cold water supply pipe.
Open the hot water tap connections so that the draw-off
volume can be set as high as possible.
Once water has been discharged from the tap connections,
do not interrupt the cold water flow; this will ensure that the
heat exchanger will be fully vented and that any impurities or
residue will be discharged.
