Replacing the main nozzle 2
Proceed as follows:
– The main nozzle 2 is visible after detaching the
burner cover (see Fig. 9). It is unscrewed with a
special screw key.
– Unscrew the nozzle and insert the new nozzle as
specified in the main nozzle table. The nozzle
must be screwed in fully and firmly (torque
1.5 Nm) (metallic seal).
– Please do not forget to stick the new adhesive
label included with the nozzle set over the old
adhesive label on the gas connection, thus
documenting the changeover to a different gas
type.
Checking functions
The flames are adjusted correctly if no yellow tips
are visible and if they do not go out when switching
over swiftly from the high to the low setting.
Adjusting the primary air
The primary air setting for different gases is only
defined by the diverse nozzle shapes and therefore
does not require adjustment.
