Gas adjustments
The hose must be connected as shown in Fig. 1 and 2, in
compliance with the local regulations.
Natural gas
Use outlet union GN for natural gas.
The hose must be connected to the outlet union and secured
using hose clamp B (Fig. 1). A mechanical connection can also be
used where appropriate. To make this connection, remove the
NG nut from the tip of the manifold. Place the extra seal that is
placed in the injector set on the connector to the appliance, and
then assemble the connector to the appliance. The connector to
the appliance must be ½” threaded female.
Butane/Propane gas
Use outlet connector B/P for Butane/Propane gas. The hose must
be connected to the outlet union and secured using hose clamp B
(Fig. 2).
The hose must not be longer than 2 m. It must be a standard hose
and replaced within the date printed on it.
Important:
Close the gas supply cock before carrying out any
maintenance operation.
Connection details: see the specific regulations for your country.
Use pressure regulators that are suitable for the gas
pressure values given on the Product Description Sheet
supplied separately.
If the appliance is arranged for a type of gas different from that
available, it is necessary to change the injectors, adjust the
minimum flame and change the outlet union.
Carry out the following operations to change the hob injectors:
remove the pan supports, remove the burners and burner caps
(see Fig. 3); change the injector (Fig. 4) and replace it with one
suitable for the new type of gas (see table on the separate Product
Sheet).
Replace the gas setting label with the new one
included in the injector bag.
Refit everything by proceeding in reverse order, making sure to
correctly fit the burner cap on the burner.
Minimum for hob taps
NB: The appliance injectors must be replaced by an
authorised technician.
For appliances equipped with Flame Failure Devices and
microswitches, the control panel must be removed in order to
safely access the adjusting screw.
To adjust the minimum flame, proceed as follows
•
Light the burner and turn the knob to min. ; remove the tap
knob (Fig. 5). Insert a small screwdriver in the tap pin (Fig. 6).
Turn the adjustment screw anticlockwise to increase the flame,
or clockwise to decrease it. Adjustment is correct when the flame
is approx. 3 - 4 mm.
The adjustment screw must be completely screwed down for
butane/propane gas.
Make sure the flame does not go out when switching straight
from high to low flame and vice versa.
Refit the knob.
