Danger
CO formation as a result of incorrect burner
adjustment can have serious health implications.
Carry out a CO test before and after work on
gas appliances.
Operation with LPG
Purge the LPG tank twice on commissioning/replace-
ment. Vent the tank and gas connection line thoroughly
after purging.
01. Close the gas shut-off valve.
02. Undo clips and remove cover panel
03. Undo screw in test connector
but do not remove it. Connect the pressure gauge.
04. Open the gas shut-off valve.
05. Test the static pressure and record it in the report.
Set value: Max. 57.5 mbar (5.75 kPa).
06. Start the boiler.
Note
During commissioning, the appliance can enter a
fault state if there are airlocks in the gas line.
Reset the appliance after approx. 5 s (see operat-
ing instructions).

Note
Use a suitable measuring device with a resolution
of at least 0.1 mbar (0.01 kPa) to check the supply
pressure.
Implement measures as indicated in the table
