Warning notes
To avoid injury to persons, damage to property or the environment, the following
warning notes must be observed!
Do not open, interfere with or modify the combination gas valve!
 All activities (mounting, installation and service work, etc.) must be carried out by
qualified staff
 Before making any wiring changes in the connection area, completely isolate the
plant from mains supply (all-polar disconnection). Ensure that the plant cannot be
inadvertently switched on again and that it is indeed dead. If not observed, there is
a risk of electric shock hazard
 Ensure protection against electric shock hazard by providing adequate protection
for the connection terminals
 Each time work has been carried out (mounting, installation, service work, etc.),
check to ensure that wiring is in an orderly state and make the safety checks
 Fall or shock can adversely affected the safety functions. Such valves must not be
put into operation even if the unit does not exhibit any damage

Use a suitable screwdriver to open or close manually the screws of the pres-
sure test points. Observe
the permissible tightening torque (refer to «Technical
Data»).
If this is not observed, the threaded connections of the pressure test
points might get damaged, which can lead to loss of tightness
