Connecting A Heater To A Heating System - Dražice OKC 300 NTR/1MPa Operation And Installation Manual

2.4 CONNECTING A HEATER TO A HEATING SYSTEM

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; 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. Should the
system work with priority heating of hot service water using a three-way valve, always follow the
installation instructions of the three-way valve's manufacturer.
