Adjusting the low flame (gas oven FG1 Fig. 3)
After having removed the control panel, adjust the low
flame screw (N) as follows:
- when using LPG, the screw 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 minimum output
position.
3- Adjust the minimum flow by means of the screw N. The
flow increases by loosening the screw and decreases by
tightening it.
4- Once the flame judged as suitable for a minimum
setting has been obtained, check that it corresponds to
the minimum flow indicated in Burner Table.
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 minimum flow screw and repeat the
EN
check.
FG SERIES GAS OVEN AND TUTTOFORNO T
Replacing the burner nozzle
(gas oven type FG Fig. 4.1)
Remove the bottom panel. Loosen screw (2) fixing the
primary air bushing and push the latter into the Venturi
tube. The nozzle is now perfectly accessible.
After replacing the nozzle according to the type of gas
being used and the technical data, reassemble everything
and adjust measure "H" (see Burner Table).
Replacing the burner nozzle
(Tuttoforno T Fig. 4.2)
Remove the left-hand bottom panel inside the cooking
chamber. 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 Burner Table).
Adjusting the pilot flame (gas oven Fig. 4.1 and 4.2)
Remove the bottom panel (Fig. 4.1).
Remove the left-hand bottom panel (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 control 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 minimum output
position.
3- Adjust the minimum flow by means of the screw 36.
The flow increases by loosening the screw and
decreases by tightening it.
4- Once the flame judged as suitable for a minimum
setting has been obtained, check that it corresponds to
the minimum flow indicated in Burner Table. This check
must be effected by means of the "volumetric method"
described above, i.e.:
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 minimum flow screw and repeat the
check.
APPLIANCE SAFETY SYSTEMS
Safety valve: a valve with a thermocouple stops the gas
flow from reaching the main burner in the event that the
pilot flame goes out.
To restore the operation, repeat the steps relevant to
igniting the pilot device.
Safety thermostat: stops the gas flow in the event of
serious anomalies.
The safety thermostat is reactivated manually and, to
restore it, it is necessary to unscrew nut "A" and press
button "B" (see fig. 7.1). If the safety thermostat starts up
again, 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.
- Clean the parts with detergent, water and a suitable
utensil, rinse and dry.
- Make sure when reassembling the parts that they are
slotted in correctly.
