PLUMBING FIXTURE
Power water connects to pipes with 3/4“ thread in the bottom part of the heater. Blue –
cold water supply, red – hot water outlet. For potential disconnection of the heater, the
service water inlets and outlets must be provided with screw coupling Js 3/4“. The safety
valve is mounted on the cold water inlet identified with a blue ring.
Each hot service water pressure heater must have a membrane spring loaded with a safety
valve. Nominal clearance of safety valves is defined by standard.
300 l heaters are not
equipped with a safety valve.
The safety valve must be easily accessible, as close to the
heater as possible. The input pipes must have at least the same clearance as the safety valve.
The safety valve is placed high enough to secure dripping water drain by gravity. We
recommend mounting the safety valve onto the branch led above the heater. This allows
easier exchange without having to drain the water from the heater. Safety valves with fixed
pressure settings from the manufacturer are used for the assembly. Starting pressure of a
safety valve must be identical with the maximum allowed heater pressure, and at least 20%
higher than the maximum pressure in the water main (Table 10). If the water main pressure
exceeds such value, a reduction valve must be added to the system.
No stop valves can be
put between the heater and the safety valve.
During the assembly, follow the guide
provided by the safety equipment manufacturer.
