5.8. Filling the heating system and checking for leaks
CAUTION: Health hazard due to contamination of usable water!

Strictly adhere to national regulations and standards on the prevention of usable water
contamination.

Ensure compliance with EN 1717.
NOTE: Damage to the system due to frost!
If the heating system along with pipelines is not installed in a manner that protects against freezing:

Fill up the heating system with anti-corrosion and anti-freeze agent characterized by low freezing
temperature.
NOTE: Damage to the system due to improper water quality!
Depending on the quality of water, the heating system may be damaged due to corrosion or limescale.

Adhere to the requirements relating to the quality of water used for filling.
In the case of open heating systems, act in accordance with local
provisions.
NOTE: Damage to the system due to too frequent addition of water!
Frequent addition of water may cause, depending on the water quality damage
of the system due to corrosion or limescale.

Ensure proper ventilation of the heating system.

Check the heating system for leaks.

Check the expansion vessel for proper operation.
The hand of the manometer must be above the red hand. The red hand must be set to the required
operating pressure.

Check the operating pressure in the heating system.
If the manometer hand is below the red hand, it means that the operating pressure is too low.


above the bottom of the boiler.

Fill up heating water or drain through the filling-drain valve until obtaining the desired operating
pressure.

When filling up, vent the heating system.

Check the operating pressure again.
Water can be supplied from the water supply system through the drain plug, using a flexible hose that
should be disconnected from the boiler after filling up the installation and closing the drain plug.
