Handling
Assembly
Connecting gas plug-in hose
INFO!
When mounting, also observe the instructions for use of the relevant gas socket.
Produce the threaded connection then the plug connection.
INFO!
If the plug is difficult to connect, lubricate the plug with tap grease in acc. with DIN EN 377.

Push the plug as far as it will go into the gas socket.
The markings on the gas socket and the plug must match.
-
Turn the plug anti-clockwise by 90°.
The connection is secured in this way.
Leakage test
The installer must perform a leakage test (load and leakage test) on the gas installation before commissioning.
The general rules of engineering must be observed.
E. g. the following regulations apply:
DVGW-TRGI 2008
DVFG-TRF 2012
INFO!
The gas plug-in hose must not be included in the leakage test.
The connector must be checked for leaks by suitable means after the gas has been filled.
The result must be documented.
Maintenance
The gas installation must be given a visual inspection, e. g. by the owner, once a year.
Particular attention should be paid to damage, e. g. kinks or corrosion.
Serviceability and leak tightness must be checked every 12 years by an installation contractor.
