3. Part : INSTALLATION AND PREPARATIONS FOR USE
Adjusting The Reduced Flame Position
The flame length in the minimum position is adjusted with a flat screw located
on the valve. For valves with FFD, the screw is located on the side of the valve
spindle. For valves without FFD, the screw is located inside the valve spindle.
For easier reduced flame adjustment, we advise to remove the control panel
(and microswitch, if present) during adjustment.The position the by pass screw
must be loosened in transformation from LPG to NG. In transformation from NG
to LPG, the same screw must be fastened. Make sure that the appliance is
unpluged from the electric current and the gas feed is open.
To determine the min. position, ignite the burners and leave them on in minimum
position. Remove the knobs because the screws are accesible only when the knobs
are removed. With the help of a small screwdriver fasten or loosen the by pass
screw around 90 degrees. When the flame has a length of at least 4mm, the gas is
well distributed. Make sure that the flame does not die out when passing from the
maximum position to the minimum position. Create an artificial wind with your
hand toward the flame to see if the flames are stable. For oven burner, operate the
oven burner at min. position for 5 minutes, then open and close the oven door for 2-
3 times to check the flame stability of the burner.
Changing the gas inlet:
For some countries, the gas inlet type can be different for NG/LPG gases. In
such a case, remove the current connection components and nuts (if any) and
connect the new gas supply accordingly. In all conditions, all components used
in gas connections should be approved by local and/or international authorities.
In all gas connections, refer to the "ASSEMBLY OF GAS SUPPLY AND LEAKAGE
CHECK" clause explained before.
