gas oven

Changing the burner injector

Make sure that the oven is not 

connected to the electric power supply.

Open the oven door completely.
Remove the burner by unscrewing 

its screws, then unscrew the injector 
and replace it. Reassemble the burner.

Adjusting the minimum 

The oven thermostat is equipped 

with a by-pass for the minimum. 
When the type of gas is changed, this 
adjustment must be adapted as follows:

If there is a glass front panel, it has 

to be removed by unscrewing the two 
fi xing screws (fi g 4).

If there is a metal front panel, the 

adjustment can be done thorugt the 
opening, which is on the left side of the 
knobs (fi g 5).

Light the oven and let it burn at the 

maximum temparutere for at least 30 

minutes. Turn the thermostat knob to 

the minimum and adjust the by-pass 

to the minimum so that you achieve a 

reduced  by  stable  fl ame.  Perform  this 

operation with the oven door closed.

Use  a  fl at-head  screwdriver  on  the 

by-pass  screw.  It  is  suffi cient  to  loosen 
the screw several turns to adjust the 
minimum when changing from liquid 
gas to natural gas. Important: once 
adjusted the burner, check that the 
minimum fl ame is maintained, test ing if 
by repeatedly opening and closing the 
oven  door.  If  the  fl ame  goes  out,  adapt 
the by-pass adjusment.

Complete  the  operations  (replacing 

the injector, adjusting the air and 
minimum),  turn  off  the  oven  and  apply 
the  new  data  plate  (which  shows  the 
type  of  gas  being  used)  replacing  the 
previous one and apply seals using 
sealing wax or similar.
