7 Mounting and Commissioning
7.1 Safety Instructions and Preparation
Prior to starting work on pressurized components:
• Close all connections to the gas line.
• Depressurize all pressurized components. Also discharge residual energies.
• Defective components charged with pressure in operation must be replaced immediately by
an appropriate expert.
Prior to starting work, ensure sufficient clearance for mounting.
Before installing the device, check whether the performance data (nameplate) and the scope of
delivery coincide with the order or the system data, i.e., make sure that the provided devices are
suitable for their intended purpose. In particular, the inlet pressure of the system must be lower than
the maximum allowable pressure of the device.
Direct contact of gas valves and fittings, i.e., the control system, with hardening masonry, concrete
walls or floors is not permitted. Provide suitable supports, working materials and protective
equipment. The minimum distances to the masonry etc. must be carried out in acc. with DVGW
worksheet G491 / G600.
Take into account the minimum clearances for maintenance as stated in the product information.
Before installing the device in the pipeline, check whether a shut-off device that interrupts the gas
flow supply to the device has been mounted upstream and downstream of the device to be installed.
Prior to commissioning, make sure that all installation work has been carried out and completed
in accordance with the data and information given in these instructions and that no unauthorized
persons stay in the danger zone.
Important information:
If a safety relief valve SL10 is used, the switching point of the SRV must be approx. 20% below the
