• This hob (Class 3) has been designed for use only as a cooking appliance. Any other use (e.g. heating rooms) should be considered incorrect and potentially dangerous.
• These instructions are valid only for the countries of destination, the symbols of which appear the appliance.

Using Your Hob

Gas burners:
Gas flow to the burners is controlled by the control knobs (5, 6, 7 and 8 on the diagrams on pages 6 & 7). There are 3 positions shown on the control panel. Turning the control knob to the positions shown below achieves the following:
Closed (OFF position)
Maximum position: Provides fast boiling function
Minimum position: Provides simmer function

The burners can be set to the desired position by turning the control knobs through the adjustment range in an anti-clockwise direction.

Igniting the Burners

The hob is fitted with a flame failure  device. Flame failure devices operateby shutting off the supply of gas to the burner in the event that the flame is extinguished accidentally. To ignite the burners, follow these instructions:

1. Lightly press the control knob down and turn the knob anticlockwise to the maximum position. Firmly press and hold down the control knob to begin the ignition process (a clicking sound will be heard). Hold down the control knob for a few seconds after ignition to allow the safety device to detect that the burner is lit.
2. Once the burner is lit, adjust the burner power to the required position.

Please note:

• The ignition device should not be operated for more than 15 seconds.
• If a burner does not ignite, or turns off accidentally, turn the control knob to the ‘off’ position, and wait for one minute before attempting to reignite the burner.
• If the burner does not ignite, repeat the ignition process with the burner at the minimum position.

Efficient Use of Your Hob

The hob is equipped with burners of different sizes, designed to accommodate most shapes and sizes of pan. For best results, only use pans with flat bottoms and choose an appropriate burner depending on the size of the pan. The most efficient use of the hob is shown below, where the pan and burner are correctly chosen.
Ensure that the pans do not overlap the edge of the pan stand, or cover the control panel. The table below shows the sizes of pan that should be used with each burner:

Burner Size| Minimum Pan Diameter (cm)| Maximum Pan Diameter (cm)
---|---|---
Auxiliary| 10| 14
Semi-Rapid| 16| 18
Rapid| 20| 22
Triple| 24| 26
Wok| | 36

Correct Use of the Wok Pan Adaptor

The wok pan adaptor is a special stand that is designed to be fitted over the triple ring burner to give support to round bottomed woks. When using a wok, always place the wok pan adaptor in position over the pan support on the triple ring burner as shown in Fig.6.

IMPORTANT:

• The wok pan adaptor (Fig. 6) must be placed over the pan support on the triple ring burner.
• Do not use the wok pan adaptor for standard flat bottomed pans.

Care and Maintenance

As the hob has a stainless steel or enamel surface, you should use a nonabrasive cleaner. Any abrasive cleaner (including Cif) will scratch the surface and could erase the control panel markings. Stainless steel can be effectively cleaned by simply using a dilute solution of water and mild detergent and drying to a shine with a clean cloth.
Over time with use, the stainless steel surface may discolour; this is normal and does not constitute a fault with this appliance. Proprietary stainless steel cleaners are available.

IMPORTANT:

• Steam cleaners must not be used when cleaning this appliance.
• Ensure that all parts are correctly replaced after cleaning, before attempting to use the hob.
• After removing the pan stands, ensure the rubber pads are in place on the base of the pan stands before repositioning the pan stands straight and level on the hob.

What to do if you smell gas:

1. Open doors and windows
2. Turn the gas supply off
3. Call TRANSCO on : 0800 111 999

Total rated gas input : 11.3kW
Mains electrical voltage:230 – 240Vac, 50Hz

If Your Hob is Not Working

1. Check that the mains supply has not been switched off.
2. Check that the fuse in the spur has not blown.
3. Ensure that the burner components are not excessively soiled as this can lead to ignition problems.

• Replacement injectors
• LPG identity plate

Instructions to fit replacement injectors:

1. Disconnect the appliance from the gas and electrical supplies.
2. Remove burner components and pan supports.
3. Remove the injectors and replace with the corresponding injector as shown in the table on page 17.

Setting up minimum flow rates:

1. Remove the control knobs.
2. Turn on the LP gas supply, light the burners and turn the controls to the minimum position, as indicated by the small flame.
3. Insert a 2.5mm screwdriver into the hole at the top of the tap and turn the adjustment screw fully clockwise as shown in Fig.9.
4. Turn the controls to maximum position then quickly to the minimum position – make sure the flame does not extinguish.
5. Replace the knobs.

LPG to Natural Gas Conversion

This hob can be converted from propane operation at a nominal inlet pressure of 37mbar or butane operation at a nominal inlet pressure of 28/30mbar to natural gas at 20mbar. This conversion must only be carried out by a competent person (i.e. a Gas Safe registered fitter).

Required:

• 7mm AF nut spinner

• NG identity plate

Fitting the Hob

Unpacking the hob:
Take care not to lose or mishandle any parts.
Fitting position of the hob:
This appliance must be installed in accordance with the dimensions in Fig. 11 on page 21 of this manual and a minimum of 150mm away from any adjacent vertical surfaces, e.g. a tall cupboard end panel. This may be reduced to 100mm if the adjacent surface is resistant to fire (tiles or steel, for example). These dimensions are shown in Fig. 11.
If fitting a cooker hood above the hob:
If a cooker hood is to be installed above the hob, the height of the hood above the hob must be at least 700mm (750mm is recommended) (Fig. 12). If the instructions supplied with the hood dictate that the hood must be installed at a height greater than 700mm, then that height is the minimum required.
Wall furniture requirements:
The minimum height of any cabinet immediately above the hob is 760mm. The minimum height of any adjacent units (including light pelmets) is 400mm, unless they are manufactured from a material resistant to fire (steel, for example)
Notes:

• Do not position this appliance above a refrigeration unit. The heat generated may cause the refrigeration unit to fail.
• This appliance is designed to be installed into cabinet units capable of withstanding temperatures 65°C above ambient or greater (typically 80-90°C).
• The rear wall or splashback the hob is to be fitted in front of must be made of flame resitant material
• If there is no oven to be built in below the hob it is recommended that, an isolation shelf should be fitted to protect the user from high temperatures. If the hob is to be installed above a working drawer, then a partition should be fitted to protect the contents and user from the heat generated during use. This should be fitted at least 15mm below the hob. This panel should have a ventilation space at the rear of greater than 30mm as shown in Fig. 10.
• Never place perishable foods in the cupboard below the appliance.

How to Install the Hob

1. Make the required hole in the worktop. Note that before doing this, check the instructions supplied with any cooker hood to ensure that you will have the required clearance. The cut-out (Fig. 11) shows a minimum 50mm gap from the wall or splashback, if fitted, to the cut-out edge.

2. Position the hob seal, as shown in the diagram below (Fig. 13), ensuring that the ends meet without overlapping. Do not use silicone type sealant.
   NOTE: The seal is supplied already fitted to the hob on some models, for your convenience.

3. Secure the hob to the worktop using the fixing brackets and screws supplied, as shown in the following diagram (Fig. 14). Remove any excess seal after tightening the brackets.
