BURNER ADJUSTMENT

2) Burner "MINIMUM" adjustment:

Work surface burner adjustment: follow the instructions below to adjust the work surface burner minimum:

1) Light the burner and set the knob to the MINIMUM position (small flame).

2) Remove the knob of the valve that is press fit on the rod of that valve.

3) If the cooker is not equipped with safety valves on the surface burners, insert a small slotted screwdriver into the hole

on the valve rod (Fig. 12) and turn the choke screw to the right or left until the burner flame is adjusted to minimum. If the

cooker is equipped with safety valves, the choke valve is not located in the rod hole, but on the valve body (see fig. 13).

4) Make sure that the flame does not go out when switching quickly from the MAXIMUM to the MINIMUM position.

WARNING: The above-mentioned adjustment should be made only with methane gas burners, while for those

operating with liquid gas the screw must be locked at the end in a clockwise direction. The grill

burner always operates at maximum and therefore no minimum adjustment is required.

APPLIANCE ELECTRIC CONNECTION:

The electric connection must comply with the current legal standards and regulations.

Before making the connection, check that:

- The system electrical rating and the current outlets are adequate for the maximum power output of the appliance (see

the label applied to the bottom of the casing).

- The outlet or the system is equipped with an efficient ground connection in accordance with the current legal standards

and regulations. The company will not be responsible for the non-compliance with these instructions.

When the connection to the power supply network is made using an outlet:

- If the power cord is supplied without a plug, apply a standard plug that is suitable for the load indicated on the label.

Connect the wires according to the diagram shown in FIG.15 and check that:

letter L (phase) = brown wire;

letter N (neutral) = blue wire;

ground symbol

= green-yellow wire;

- The power cord must be positioned so that an overtemperature of 75 K will not be reached at any point.

- Do not use reductions, adapters or splitters since they might cause false contacts and lead to dangerous overheating.

When the connection is made directly to the electric network:

- Use a device that ensures disconnection from the mains in which the contacts are opened to a distance that permits

complete disconnection according to the conditions for over-voltage category III.

- Remember that the ground wire must not be interrupted by the circuit-breaker.

- As an alternative, the electric connection can also be protected by a high-sensitivity residual current circuit-breaker.

- It is highly recommended to attach the special green-yellow ground wire to an efficient ground system.

WARNING: If the power cord is replaced, the ground wire (yellow-green) connected to the terminal, should be

longer than the other wires by about 2 cm.

WARNING: If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a

similarly qualified person in order to avoid a hazard.

For New Zealand - This cooking range must be connected to the supply by a supply cord fitted with an appropriately

rated plug that is compatible with the socket-outlet fitted to the final sub-circuit in the fixed wiring that is intended to

supply this cooking range.

BEFORE LEAVING

When the installation is complete, always check for gas leaks using a soapy solution. Never use a flame to make this

check.

Ignite all burners on high flame to ensure correct operation of gas valves, burners and ignition. Turn gas taps to low

flame position and observe each burner to ensure they ignite completely at all ports and that the flame is stable. Conduct

these checks for each burner individually and concurrently.

When satisfied with the appliance, please instruct the user on the correct method of operation. In case the appliance fails

to operate correctly after all checks have been carried out, please call the Bertazzoni Service Centre.
