3.9 Storage tank
NOTICE
In principle it is not necessary to use a storage tank for the system to run smoothly.
However we recommend that you use the system with a storage tank, as this ensures a
continuous supply of fuel in the ideal output range of the boiler.
For the correct dimensions of the storage tank and the line insulation (in accordance with
ÖNORM M 7510 or guideline UZ37) please consult your installer or Froling.
3.10 Boiler ventilation
r Fit the automatic ventilating valve at the highest point on the boiler or at the ventilation
connection (if present).
Ä This ensures that air in the boiler is constantly expelled, thus preventing
malfunctions caused by air in the boiler
r Check that the boiler ventilation is working properly
Ä After installation and periodically according to manufacturer’s instructions
Tip:
r Fit a vertical pipe as a calming section in front of the automatic ventilating valve in
such a way that the ventilating valve is positioned above the water level in the boiler
Recommendation:
r Fit a microbubble separator in the pipes to the boiler
Ä Follow the manufacturer's instructions!
