Bertos G6F2BH6 Mode D'emploi page 113

Unscrew and remove the primary air regulator 1, then
replace the nozzle.
After replacing the nozzle according to the type of gas
being used and the technical data, reassemble everything
and adjust measure "H" (see table on burners).
Adjusting the pilot flame (gas oven Fig. 4.1 and 4.2)
Remove the bottom panel (Fig. 4.1).
Remove the bottom (Fig. 4.2)
Remove securing screw (11). (Fig. 4.3)
Use a screwdriver to set the internal adjusting screw
according to the gas used.
Replace securing screw (11) and relative gasket.
When using LPG, the internal screw must be tightened all
the way down.
Adjusting the low point control (gas oven Fig. 5)
After having removed the contro panel, adjust the low
flame screw (36):
- when using LPG, it should be fully screwed down;
- if natural gas is used:
1- Find the knob of the corresponding cock.
2- Turn the burner on and turn it to the minimun output
position.
3- Adjust the minimun flow by means of the screw 36.
The flow increases by loosening the screw and
decreases by tightening it.
4- Once the flame is considered suitable for a minimum
setting , check that it corresponds to the minimum
capacity indicated in the table on burners.
5- If the power is less than the value in the table, turn the
minimum screw again and repeat the check
6- If the power is greater than the value indicated in the
table, tighten the minimun flow screw and repeat the
check.
FULLPLATE
Replacement of burner nozzles of TP40 gas radiant
hotplate (Fig. 7). To replace nozzle (1); remove the control
panel by loosening the screws on the bottom edge.
Remove the air regulator (2) by loosening the screws.
Replace the nozzle (1) (see table on burners).
Replacement of burner nozzels of TP80 gas radiant
hotplate (Fig.9)
Remove the hotplate, remove the two fixing screws of
the insulating panel on the combustion chamber bottom.
Remove the air adjustment by unscrewing the fixing
screw
and replace the nozzle (see burners tables). Reassemble
the air adjustment and reposition the insulating panel.
Adjusting the low point control (fullplate Fig. 2)
After having removed the control panel, adjust the low
flame screw (2):
- when using LPG, it should be fully screwed down;
- for operation with methane:
1- Locate the knob of the corresponding cock.
2- Turn the burner on and turn it to the minimum output
position.
3- Adjust the minimum flow rate with screw 2. Unscrew to
increase and tighten to decrease the flow rate.
4- Once the flame judged as suitable for a minimum
setting has been obtained, check that it corresponds to
the minimum flow indicated in the table on burners.
5- If power is lower than the table, further loosen the
minimum screw and repeat the check.
6- If the power is greater than the value indicated in the
table, tighten the minimum flow screw and repeat the
check.
Replacing the pilot flame nozzle of the fullplate (Fig. 7)
The pilot flame operates with a fixed nozzle and fixed air.
To reach the pilot flame, remove the control panel as
described above and, if necessary, remove the round
central plate of the hotplate.
Use the table on burners to replace the nozzle (B) with a
suitable one, after having loosened nut (F).
Checking the primary air of the main burner
After changing the nozzle, as described above, check
that measure H (Fig. 7) of the primary air adjustment is in
accordance with the data in the burner table. To adjust the
position of the clamp (2), unscrew it and slide it.
APPLIANCE SAFETY SYSTEMS
Safety valve
A thermocouple valve stops the gas flow from reaching
the main burner in the event of the pilot flame going out.
To restore operations, repeat the directions relevant to
igniting the pilot device.
Safety thermostat (only ovens)
Stops the gas flow in the event of serious anomalies. It is
reactivated manually and, to restore it, it is necessary to
unscrew nut "A" (fig. 10). If the safety thermostat starts up,
call technical assistance.
MAINTENANCE
Attention!
Before effecting any maintenance or repair operation,
disconnect the appliance from the gas or electric
power supply.
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 described in
paragraph "Checking the functions".
Whenever the gas ring burners need cleaning, proceed
as follows:
- remove the grids, the burner caps and the burners.
