Surface burners supplied do not require
adjustment of primary air. A correct flame
has distinct internal cones of blue and green
colour. A short, humming flame or long, yel
-
low and smoking one, without clearly outlined
cones, shows that there is poor quality of
gas in the household piping or a damaged
or soiled burner. In order to check the 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.
INSTALLATION
Caution!
Adapting the appliance to a different
type of gas other 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 responsibility of the user and the
fitter.
Gas supply to surface burners is opened and
set by knobs, see figure below 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.
To exchange the burner
nozzle – unscrew the
nozzle with special socket
spanner No 7 and replace
with a new one accord-
ing to a type of gas (see
tables).
Caution!
After adjustment is completed, put on
a label indicating the type of gas to
which the cooker is now adapted.
