2.3 CONNECTION OF INDIRECT HEATER TO HOT WATER HEATING
SYSTEM
It is recommended to install stop valves on the heating water inlet and outlet (for possible
dismantling of the heater). The valves have to be as close to the heater as possible to avoid
higher thermal losses
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.
After connecting the heater to the water supply, the hot water heating system, the electric
network, and after testing its safety valve (based on the valve manual attached), the heater
may be put into operation. Before opening the power supply, the tank must be filled with
water. The process of first heating must be executed by licensed professional who has to
check it. Both the hot water outlet pipe and safety armature parts may be hot.
