5.2 De-aerating
De-aerating the gas line by closing the tap to the gas connection and
unscrewing the screw on the measuring nipple for the connection pressure.
Connect a plastic hose, open the tap and drain the gas in a safe place. When
the de-aerating is completed, be sure to refit the screw on the measuring
nipple.
5.3 Tightness control
When checking for leakage, the solenoid valve must be closed. A pressure
gauge is connected to the measuring nipple ”Pa”, see picture. The test
pressure in the system must not be higher than max. connection pressure,
see data plate. If leaks are found during measurement, locate the source
using soapy water or leak detection spray. After sealing: check the tightness
of the gas fixture again.
