INSTALLATION
Burner of SOMIPRESS type (according to the "Somipress" symbol on burner components)
Type of gas
G20 2H - 20mbar
In order to perform adjusting operations, take off the knobs. Adjusting elements of the oven
burner are accessible after drawing out the oven chamber floor.
Caution!
The cookers provided by the manufacturer have burners which are factory-adapted to use
the gas specified on their data plates.
Surface burners applied do not require adjust-
ment of primary air. A correct flame has dis-
tinct internal cones of blue and green colour.
A short, humming flame or long, yellow and
smoking one, without clearly outlined cones,
shows improper quality of gas in the house-
hold piping or a damaged or soiled burner.
In order to check a flame, heat a burner for
around 10 minutes with a full flame, and next
turn the valve knob to the economical flame
position. The flame should not go out or jump
onto the nozzles.
In cookers with a safety device, a knob with
a surface burner safety valve is used, fig.
Knobs should be adjusted with the burner
switched on and set to the economical flame
position, using an adjustment screwdriver of
the 2.5 mm size.
Exchange of a burner noz-
zle – unscrew the nozzle
with special socket span-
ner No 7 and replace with
a new one according to a
type of gas (see tables).
