Turning the boiler – tank suite on
• Open the heating system shutting valves (boiler and tank).
• By turning on the boiler top-up valve, increase the heating system water pressure to the
recommended value (1.2 – 1.6 bar).
• Open the tank hot water shutting valves and then open a hot water tap. Wait until a con-
tinuous stream of water flows out of the tap and then turn the tap off.
• Turn the boiler on and set the temperature on the operation thermostat to the maximum
value (85˚C).
Important: The hot water tank heating time increases with the decreasing heating water
temperature.
• Always set the temperature on the tank operation thermostat by about 10 ˚C lower than
the required temperature.
• Check if the whole system (boiler, tank and entire interconnection) functions correctly.
