PRESSURE STABILISER
To adjust gas pressure rotate the screw illustrated in
Figure 15.
Screw in to increase pressure; loosen the screw to redu-
ce it.
Never leave the adjuster screw turned as far as it will go
because, if you do, the pressure stabiliser will not work.
Maximum burner power can only be obtained when there
is suitable pressure upstream from the gas valve.
GAS FILTER
To clean the gas filter close the gas check valve on the
piping; remove the filter cover, extract the filtration cartrid-
ge and clean it carefully: if possible, clean with compres-
sed air.
When refitting the lid take care not to pinch the O-ring
and check that there are no gas leaks.
