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.
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
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).
A professional installer must adjust the small
flame on-site in your home. The adjustment
depends on the type of gas and its pressure.
Oven burner flame adjustment applies to
2K 25mbar gas only. The process involves
adjusting the appropriate air gap in the burner
injector by positioning of the adjustment
cover.
Increase the gap to increase airflow or reduce
the gap by positioning the curtain towards the
nozzle to reduce the airflow. The properly
adjusted burner should produce a less
intense flame than the surface burners. After
adjustment, secure the cover with screws.
A professional installer must adjust the airflow
and the small flame on-site in your home. The
