Adjusting the pilot burner (Fig. 1)
To get at the pilot burner, remove the control panel
(as previously described). Unscrew nut (34) and
using a screwdriver adjust the by-pass. For use with
LPG, the adjusting screw must be fully screwed
down. Tighten the nut, making sure the gasket has
been inserted.
Adjusting the primary air
To adjust the primary air according to the data in ta-
ble (1), the fixing screw (99 - Fig. 1) must be loose-
ned.
MAINTENANCE
Attention!
Before carrying out any maintenance or repair
work, disconnect the appliance from the mains.
The following maintenance programme should be
carried out at least once a year:
- Check that all the safety and setting devices are
working properly;
- Check that the burners are working properly with
regard to:
- ignition
- combustion safety;
- Check the functions of the appliance as descri-
bed in paragraph "Checking the functions", page
8;
- Check the gas venting path (make sure the gas
is correctly evacuated).
REPLACING PARTS
All parts must be replaced by authorised techni-
cians only!
To replace the following parts, remove the control
panel (after unscrewing its fixing screws). It is advi-
sable to empty the tank.

fixing screws. The valve may now be removed and
replaced with a new one. Replace and screw down
all parts in the correct order.

Unscrew the fixing nut and the nut fixing the bulb in
the tank, disconnect and insert the new part.
Burner (31 - Fig. 1)

chamber. Replace the burner.
Thermocouple (38 - Fig. 1)
Unscrew the nipple fixing the thermocouple to the
