2.3 PLUMBING FIXTURE

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 safety valve with membrane spring.

Nominal clearance of safety valves is defined by standard. Heaters are not equipped with a

safety valve. The safety valve must be easily accessible, as close to the heater as possible.

The inlet 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 a branch pipe. 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 to the maximum

allowed heater pressure and at least 20 % higher than the maximum pressure in the water

main (Table 5). 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.
