When assembling the device, in addition to the points listed here, any conditions imposed by the
approval authority, all local regulations and the requirement of the DVGW and TRGI must be strictly
observed.
Connections
Connect the gas control line to the gas line. Make sure that the connection is deenergized. Gas type
and gas pressure must be suitable for the control line.
The prerequisite for achieving the nominal heat output is compliance with the gas-side supply
pressure (see data sheet). The nominal heat output may not be achieved if the supply pressure falls
below the specified value under operating conditions.
Guide drain valve into non-hazardous area.
Assembly and wire all sensors (e.g., room thermostats).
Each installation must be equipped with an emergency switch.
Tightness
Check the gas line, connections and gas control system for tightness using a test device.
