4.1 Gas supply rubber pipe
The condition of the gas supply pipe should be
checked periodically (once a year) and replaced
by the date printed on the outside of the pipe
and if there are signs of cracking, cuts, scratches
or burns, or if it is no longer flexible but hard
and plastic.
The pipe must be suitable for use with liquid gas
and comply with the applicable standards.
4.2 Electricity supply cable
If the electricity supply cable needs replacing,
therefore only authorised LOFRA technicians
may replace it. Use HO5FVV-F cables only.
he earth wire (yellow/green) must be at least 2
cm longer than the other two phase wires.
This ensures that the electrics are safe should
the wire be pulled accidentally.
For the cookers with a gas oven and an electric
grill, use a 3x1,5 mm² HO5RR-F cable, for
cookers with electric oven and grill, use a 3x1.5
mm² HO5VV-F cable with a maximum external
diameter of 9 mm. In the case of current
exceeding 16A shall have the power section 2.5
mm².
4.3 Removing and fitting the
oven door
Open the oven door completely, insert the anti-
rotation device (A) in the hook of the hinge rods.
Hold the oven door by the sides and slowly
close it until you can feel a certain resistance;
simultaneausly lift the door and force it towards
its closed position in order to slide it out by
freeing the hinge lock from the kitchen’s body.
To refit the door repeat the above instructions
in reverse making sure the hinge lock is correctly
fitted.
For the CURVA models insert an anti-rotation
hinge in the appropriate holes. Hold the door by
the sides and slowly close it until you can feel a
minimum position, remove the knob and adjust the previously loosened screw until
the flame is lowered but stable, even when rapid changes from maximum to minimum
are made and the oven door is opened or closer quickly.
N.B.:
For liquid gas setting, the oven burner minimum is set by fully tightening the thermostat by-
passes.
Gas grill burners
To convert the gas to this type of burner, see the “oven burner” instructions above. The only
difference is that the burner is in the top of the oven, and there is no need to set the minimum
because the burner always works at full power.
