The shut-off valve by the exchanger must be open and thus the flow of heating water ensured from the
hot water heating system.
It is recommended that an air release valve is fitted together with the shut-off valve on the inlet to the
exchanger, which according to requirement, especially at the beginning of the heating season, can be used to
vent the exchanger (fig. 1).
The period for heating required by the exchanger is dependent on the temperature and flow rate in the
hot water heating system. The combined heater is produced in a universal design – fitting of a shut-off valve to
the heating insert from the right or the left (fig. 1).
