To access fuse, unscrew fuse housing and remove from appliance. (See diagram).

Electric wiring requirements

The cooker MUST be installed in compliance with:

• Wiring connections in AS/NZS 3000 wiring rules.

• Local regulations, municipal building codes and other statutory regulations.

• Data plate – Gives information about the rating and is located behind the bottom of the oven door.
  For New Zealand only: The cooking range must be connected to the supply by a supply cord fitted with the 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.

• A functional switch MUST be provided near the appliance in an accessible position (AS/NZS 3000 – Clause 4.7.1).

• Wiring MUST be protected against mechanical failure (AS/NZS 3000 – Clause 3.9).

• The cooker requires a means of all pole disconnection incorporated into the fixed wiring. This MUST have a disconnection gap of 3mm.

• The cooker MUST be properly earthed.

• Disconnection in the fixed wiring must occur in accordance with the AS/NZS 3000 Wiring Rules

• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

• This range must be connected with cable of 75°C rating minimum.

• This product has passed the insulation resistance test after manufacture. If the resistance reading is low at installation, it is probably caused by moisture from the atmosphere being absorbed by the elements after the range has been produced. (Pass at 0.01M AS/NZS 3000 Wiring Rules Clause 8.3.6.3).

IMPORTANT
Before you cook in your new oven it is important that the protective oils used in the manufacture of the product be removed. Refer to ‘Before Operating your Appliance for the
First Time’ in the Using The Oven section.
Hard wiring

1. Remove rear panel.
2. Fit wires through hole at bottom centre using the appropriate gland to protect insulation of wires from the hole edge. Note that the secondary insulation of the wires will probably need to be removed to fit through gland. If the conduit to appliance is required to bend due to rear wall an elbow may be required to achieve this.
3. Set the length of wiring from the gland to terminal block, ensuring length is suficient but not excessive.
4. Make connections to terminals and engage wires into plastic clip. Cable tie as per diagram and secure plastic clip with two long screws supplied.
5. Replace rear cover.

Rated power input

Gas requirements
This appliance must be installed by an authorised person, according to all codes and regulations of:

• AS/NZS 5601.1 (particular attention to clause 6.10.1 and clause 6.10.1.11)
• Local gas fitting regulations, municipal building codes and other statutory regulations.

Unpacking
When packaging is removed from product you will notice there are several items nested in the packaging base.
The burner crowns, burner caps and trivets can be fitted to the hob.
The regulator or test point fitting installation is described in the front of the manual with UNPACKING.
The cookers come in three gas types:
Natural gas, Propane and Universal LPG. If the cooker is required to use ULPG, a conversion kit can be obtained by contacting the Customer Care Centre for details. Before installation, check that the cooker is suitable for the gas supply by looking at the data plate behind the bottom of the oven door.
The following table shows the supply and operating pressures for various supplies.

• If the regulator is placed upstream of the cooker inlet, as is normal for cookers operating on LPG, then the supply pressure and operating pressure are the same.
  The following table shows the injector sizes for each burner.

Checking pipe size
To work out a suitable pipe size for connection use the information in this table.

| NATURAL GAS| UNIVERSAL LPG| PROPANE
---|---|---|---
CONFIGURATION| Hourly gas consumption for cooker
STD Hob| 58.1MJ| 45.7MJ| 56.5MJ
WOK Hob| 60.2MJ| 48.2MJ| 58.3MJ

Also use information about the length of the run, number of elbows, tees and bends, the available service pressure and the supply requirements. AS/NZS 5601.1 will help you with this matter.
Operation ON NG

• The appliance regulator MUST be orientated so that the pressure nipple is accessible.
• The arrow showing the direction of flow MUST be pointed correctly.
• The regulator has a ½” BSP internal thread at the inlet and outlet.

Wiring connection for gas cooker
To allow for disconnection of the appliance after installation, the plug must be accessible after installation.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
Gas connection
Read these points before connecting to the gas supply:

• The cooker inlet connection point has a ½” BSP external thread.
  See diagram below.

• An NG regulator or a LPG test point fitting is supplied.

• It is recommended to fit the regulator or test point fitting to the appliance connection point, then fit either hard piping or a high level flexible connection (AS/NZS 5601.1 clauses 5.9 and 6.10.1.9) which is then attached to the consumer hard piping.

• Ensure installation allows withdrawal of appliance.

Operation on universal LPG/propane

1. The appliance inlet fitting provided MUST be orientated so that the pressure nipple is accessible.
2. The inlet fitting has ½” BSP internal thread at the inlet and outlet.

Operation on SNG

• If the cooker is to be used with SNG, then the grill burner MUST be modified by the replacement of the shutter, which fits into the throat of the grill burner.
• A conversion kit can be obtained by contacting the Customer Care Centre.

WARNING
Disconnect electric power before removing control panel.

1. Remove the control panel.
2. Remove the existing NG shutter securing screw (refer to diagram above) and slide upwards to disengage from grill burner.
3. Slide the SNG shutter into position and secure with screws.
   Testing the gas cooker

WARNING
You MUST test the cooker after installation, before you hand it over to the customer.
You MUST have a manometer and a connecting tube.

Checking the gas supply

1. Check the manometer zero point is correct.

2. Connect the manometer to the cooker pressure test point.
   This is located on the regulator or LPG inlet fitting.

3. Turn on the gas supply and the electricity (if applicable) and try to ignite the gas.
   NOTE: It will take additional time to light the gas for the first time, as air needs to be purged from the pipes.

4. Check the operating pressure for the particular gas type (see ‘Gas Type’ table).
   • For LPG cookers: Adjust the regulator if necessary (this may be remote from the cooker).
   • For Natural Gas cookers: Regulators are supplied pre- adjusted and configured by the component maker for use with Natural Gas. The appliance installer is not required to make an adjustment to obtain the correct outlet pressure setting. An arrow on the base of the regulator indicates the direction of the gas flow when the inlet and outlet of the regulator are orientated correctly.

5. When the regulator has been fitted check for leaks from the connections with soapy water.

Checking regulator function
With the appliance operating, check the outlet pressure:

1. When all the burners of the appliance are operating at maximum.
2. When the smallest burner of the appliance is operating at minimum. Under both these conditions the outlet pressure should not vary from nominal operating pressure of 1.0kPa by more then ± 20% (ie ±0.20kPa for Natural Gas).
   If the regulator does not appear to be performing satisfactorily then check the following points:
   1. If the outlet pressure is consistently too low then
   • the inlet pressure may be too low and adjustment of an upstream regulator may be needed, or
   • an upstream regulator or valve with insuficient flow capacity may be present in the gas supply line. It may be necessary to repeat the checks whilst measuring both the inlet and outlet pressure to determine if the inlet pressure is in the range 1.13-5kPa.
   2. Check that the regulator has been fitted to the gas supply line in the correct orientation.
   3. Replace the regulator if it fails to perform after the checks.

Testing burner performance

• Observe the flame appearance on each burner when set to max. If it is smaller or larger than expected, then the injector size needs checking (refer to table).
• When maximum flame appearance is correct, check the turn down setting on each burner. If incorrect, proceed as follows:

WARNING
Disconnect electric power.

1. Remove the control panel and adjust the bypass screw when valve is set to maximum. The screw is mounted on the body of each hotplate control valve.
2. Check the ignition on all burners both separately and in combination.
3. Check the operation of the electrical components, if applicable.
4. When operating correctly, show customer how to use the cooker.
5. If not operating correctly, advise the customer to ring Electrolux Customer Service Centre. Place a warning sign on cooker or if dangerous, disconnect cooker.
