Replacing the low setting nozzles (Fig. 11)
The low setting nozzles for the inner (2) and outer
(1) burners are located in the gas valve. They must
be replaced according to the new gas type and as
specified in the low setting nozzle table. Screw in
the nozzles fully and check that they are tight
(metallic seal).
If it should be necessary to correct the low-setting
nozzles (1) and (2) as the result of deviating gas
types and pressure, the flow rate can be increased
by turning to the left.
