For conversion of the appliance from
natural gas to another type of gas, or
vice versa, it is necessary to exchange
the pilot injector and the main injector.
The conversion may only be executed by
a qualified competent person.
Procedure:
1. Close the main gas tap in the gas
supply;
2. Demount the burner (see
“Cleaning”);
3. Replace the injector of the main
burner and the pilot burner with the
correct injectors from the
conversion set (see table above).
4a.
Conversion from natural gas
to LP-gas:
-
Put the pressure regulation of
the gas control block out of
operation. To do this the
temperature regulating knob
should be pulled straight
forward. Turn the
‘no pr’
(no
pressure regulation) screw
down tight (see figure10);
-
Seal this setting with lacquer;
-
Remount the burner in reverse
order;
-
Open the main gas tap.
4b. Conversion from LP-gas to natural
gas:
-
Put the pressure regulator into
operation. To do this the
temperature regulating knob
should be pulled straight
forward. Next the red plastic
cover that is now visible, should
be removed. Turn the
‘no pr’
(no
pressure regulation) screw
completely up (see figure 10);
-
Seal this setting with lacquer;
-
Remount the burner in reverse
order;
-
Open the main gas tap;
-
Set the correct burner pressure
(see table above).
5. If necessary adjust the pilot
correctly (see “Pilot adjustment”).
6. Fit the correct sticker from the
conversion set on the appliance so
that it is clear that the appliance
has been converted and on which
gas the appliance operates.
