Between the water heater and safety valve, no closing valve may be built in because
it could impede the function of the safety valve.
The heater can be connected to the domestic water supply network without a pressure-
reducing valve if the pressure in the network is lower than the nominal pressure. If the
pressure in the network exceeds the nominal pressure, a pressure-reducing valve must be
installed.
