EXAMPLES OF HEATERS CONNECTION

Connecting a heater to a heating circuit

The heater is placed on the ground, next to the heating source, or in its vicinity. The heating circuit is connected to

marked inputs and outputs of the heater exchanger; the deaerating valve is mounted in the highest place. It is

necessary to install a filter into the circuit in order to protect the pumps, the three-way valve, and backflow flaps,

and the exchanger from sedimentation. It is recommended to flush the heating circuit before the assembly. All

wiring connections must be properly insulated from heat.

If the system works with priority heating of HSW using a three-way valve, always follow the installation

instructions of the three-way valve's manufacturer.

Connecting a Heater to a Hot Water Distribution

Cold water shall be connected to an inlet marked with a blue ring and writing "HSW INLET". Hot water shall be

connected to an outlet marked with a red ring or writing "HSW OUTLET". If the hot service water (HSW)

distribution is equipped with circulation circuit, it shall be connected to the outlet marked with "CIRCULATION".

For potential drain of heater, the HSW inlet has to be provided with a "T" fixture with a drain valve. Each

individually lockable heater must be at the cold water inlet provided with a stop gate, test cock, safety valve with a

reverse flap and a pressure gauge.
