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.
2. MAINTENANCE
WARNINGS:
Before carrying out any maintenance or conversion operations, turn off the electricity
supply and close the gas upstream of the appliance. If components and/or
accessories need replacing, use only Lofra spare parts only. All the operations
hereunder must be carried out by qualified technicians in accordance with the
enclosed instructions and current installation standards.
2.1. 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.
2.2. ELECTRICITY SUPPLY CABLE
If the electricity supply cable needs replacing, therefore only authorised LOFRA technicians
may replace it. Use HO5FVV-F cables only. The earth wire (yellow/green) must be at least 2 cm
longer than the other two phase wires (fig. 5 B). 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.
2.3. 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
certain resistance; now, while forcing the door closed, lift it in order to
slide it out by freeing the hinge lock from the kitchen. To refit the door
repeat the above instructions in reverse making sure the hinge lock is
correctly fitted.
