up wait for one minute until the boiler is burning at full
load.
z Measure the gas supply pressure and enter it in the start-
up report, page 85.
The gas supply pressure must be:
– for natural gas min. 7 inch W.C. (17.4 mbar),
max. 10.5 inch W.C. (26.1 mbar), nominal supply pres-
sure 8inchW.C. (19.9mbar).
– for LPG min. 8 inch W.C. (19.9 mbar),
max. 13 inch W.C. (32.3 mbar), nominal supply pres-
sure 11 inch W.C. (27.4 mbar).
z Press the "Service" button (fig. 58, pos. 4) repeatedly
