If the separation between the two connection points is less than the
minimum bending diameter, it results in the hose ends bending in opposite
directions. This leads to fatigue fractures.
6.4 Testing for leaks
NOTICE
Use only DVGW-approved foam forming agents or those that have been
tested according to locally applying regulations!
Do not spray leak spray onto the wires of the ignition electronics.
Electronic gas detectors also react to exhaust gas (CO). Therefore, the
null calibration of an electronic gas detector should be done outdoors.
→ Test all connections inside and outside the unit for leaks according
to the "technical provisions for the gas installation" , using a gas
detector or leak spray.
6.5 Checking the connection pressure
All connections inside and outside the unit are free of leaks (see
"Testing for leaks", Page
NOTICE
The manometer should be accurate to at least 0.1 mbar.
1. Switch the unit off at the mains (switch off circuit breakers or remove
