Remove all pan supports, burner caps and
1.
distributors.
To replace the injectors, use the key that is available
2.
from our technical service with code 340847 (for
double-flame burners 340808). See table. It is
important to make sure that the injector does not
become detached during removal or fastening. They
must be properly tightened to ensure that there are
no leaks.
With these burners, there is no need to adjust the
primary air.
Fasten the distributors and burner caps to the
3.
corresponding burners. In addition to this, put the
pan supports in place on the corresponding burners.

Adjusting the gas valves
Turn the control knobs to the lowest setting.
1.
Remove the control knobs from the gas valves. A
2.
flexible rubber sealing ring will be visible. Push down
with the tip of a screwdriver on the gas valve's
setting screw.
Never remove the sealing ring. Sealing rings
prevent liquids and dirt from finding their way into
the appliance and impairing its ability to function
properly.
If necessary, use a Torx screwdriver to adjust the
3.
bypass screws:
A: For ULPG the bypass screws must be tightened
properly.
B: For Natural Gas the bypass screws must finish
flush with the fitting.
7
Make sure that the flame does not go out and that
there are no flashbacks when you turn the control
knob between the highest and lowest setting.
Never remove the gas tap axle. In the event of damage,
the gas valve must be completely replaced.
