INSTALLATION
Surface burners applied do not require ad-
justment of primary air. A correct flame has
distinct internal cones of blue and green co-
lour. A short, humming flame or long, yellow
and smoking one, without clearly outlined
cones, shows improper quality of gas in the
household piping or a damaged or soiled bur-
ner. 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.
Caution!
Adapting the appliance to a different
type of gas than that indicated by the
manufacturer of the cooker on the
data plate, or purchasing a cooker for
a different type of gas than supplied to
the house, is exclusively the responsi-
bility of the user and the fitter.
Exchange of a burner
nozzle – unscrew the
nozzle with special socket
spanner No 7 and replace
with a new one according
to a type of gas (see ta-
bles).
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.
Caution!
After adjustment is completed, place
a label indicating the type of gas to
which the cooker is now adapted.
