APPLIANCE GAS CONNECTION

Before connecting the appliance to the gas network, make sure that the data on the label attached to the food
warmer drawer or on the back of the cooker are compatible with what is indicated for the gas distribution
network.
A label attached to the last page of this handbook and in the food warmer drawer (or on the back) of the
appliance indicates the appliance adjustment conditions: type of gas and operating pressure.
IMPORTANT: This appliance must be installed in compliance with current national standards in force and used
only in a well-ventilated room.
This appliance shall be installed only by authorised persons and in accordance with the manufacturer's
installation instructions, local gas fitting regulations, municipal building codes, electrical wiring regulations,
local water supply regulations, AS/NZS 5601.1-2010-Gas Installations–General installations and any other
statutory regulations.

WARNING: It should be recalled that the appliance utilises a threaded 1/2" gas cylindrical male fitting according
to UNI-ISO 228-1.

4

For ease of service, the cooker should be connected with a Flexible Hos e, which complies with AS/NZS 1869 (AGA
Approved), 10mm ID, class B or D, between 1 - 1.2m long and in accordance with AS5601 for a high level connection.

WARNING: Ensure that the hose is not subjected to abrasion, kinking or permanent deformation and should be able to
be inspected along its entire length. Unions compatible with the hose fittings must be used and con nections tested for
gas leaks. The fixed consumer piping outlet should be at appro ximately the sam e height as the co oker connection point,
pointing downwards and approximately 200mm - 300mm in from the left han d side of the cooker. The hose should be
clear of the floor when the cooker is in the installed position. A hose restraint chain should be anchor ed to the wall to
prevent strain on the hose connections when the cooker is pulled forward.

Fit the supplied gas connectors as shown in Fig. 10 for your installation gas type. The gas inlet has a 1/2" BSP male
thread. When making the connection, take care not to apply excessive stress by counterbalancing tightening force.
Ensure that the available gas supply is the same as the gas type label affixed near the gas connection point. If not,
contact Bertazzoni for a Gas Conversion Kit.

Natural Gas

The natural gas regulator supplied must be fitted for natural gas. Ensure t he arrow on the regulator points towards the
direction of the gas flow. Commissioning Procedure - The test point pressure must be adjusted to 1.00 kPa with the
Outer Wok Burner or both Semi Rapid Burners operating on maximum flame.

Propane (LPG)

Fit the LPG test point assembly (supplied in the gas conversion kit). An AGA Approved gas regulator suitable for a
supply pressure of 2.75kPa should be part of the gas tank supply.

ANTI-TILTING CHAIN/HOSE RESTRAINING CHAIN

A chain should be fitted by the installer within 50mm of the hose connection point to prev ent strain on the hose when the
cooker is pulled forward. The chain should restrict the appliance movement to no more than 80% of the hose length.
After the chain is installed, check that there is no strain on the hose or gas connections when the c ooker is pulled as fa r
forward as the chain allows.

The cooker is also supplied with two chain s which are connected to the rear left and right of the appliance. The chains
should be connected to the wall directly behind the chains as low as possible to prevent the appliance from tilting
forward. If the appliance is installed between two cupboards, drill a hole on each side o f the cupboards, pass the chains
through the holes and anchor the chains within each cupboard. Ensure the chain connections are strong enough to
support the weight of the appliance and taught to prevent it from tilting forward.

WARNING: In order to prevent accidental tipping of the app lianc e, for e xample a c hild cli mbing onto th e open oven do or,
the stabilising means must be installed. Ensure the chains are correctly anchored to prevent the app liance from tilting
forward and to prevent strain on the hose when the cooker is pulled forward.

MAKE SURE THE ANTI-TILTING CHAINS ARE TAUGHT WHEN ANCHORED TO PREVENT THE APPLIANCE
TILTING.

ADAPTATION TO DIFFERENT TYPES OF GAS FOR COOKER TYPE M6V

BURNER ADJUSTMENT

1) 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 sm all slotted scre wdriver into the hole
on the valve rod (Fig. 12) and turn the choke screw to the right or left u ntil t he burner flam e is a djusted to minimum. If th e
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 an d 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 (se e
the label applied to the bottom of the casing).

- The outlet or the system is equipped with an efficient gr ound c onnection in accorda nce with the curren t 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, ap ply 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 o pened 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 circ uit-breaker.

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