Operation

Hob Burners

To light a burner:

• Push in the relevant control knob and turn it anticlockwise to the maximum position.
• Upon ignition, keep the knob pushed down for about 5 seconds. This allows the "thermocouple" (a safety device) to heat up and switch off the safety device, otherwise the gas supply would be interrupted.
• Then adjust the flame as required.
• If the burner does not ignite, turn the control knob to zero and try again.

To ensure maximum burner efficiency, use pots and pans with a flat bottom fitting the size of the burner used. The recommended sizes are:

Diagram Description (Fig. 1): Components of a burner assembly: A - Burner cap, B - Burner crown, C - Ignition candle, D - Thermocouple.

Important Usage Notes:

• Using a saucepan smaller than the recommended size can cause the flame to spread beyond the vessel's bottom, leading to handle overheating.
• Exercise caution when frying food in hot oil or fat, as overheated splashes can easily ignite.
• Once a liquid starts boiling, reduce the flame to a simmer.
• If control knobs become difficult to turn, contact your local Service Centre.

Maintenance and Cleaning

⚠️ Before any maintenance or cleaning, DISCONNECT the hob from the electricity supply.

The hob is best cleaned while still warm, as spillage is easier to remove.

The Hob Top

Regularly wipe the hob top with a soft cloth wrung out in warm water with a little washing-up liquid. Avoid the use of:

• Household detergents and bleaches.
• Impregnated pads unsuitable for non-stick saucepans.
• Steel wool pads.
• Bath/sink stain removers.

For heavily soiled hob tops, use a cleaning product such as Hob Brite or Bar Keepers Friend.

Pan Supports

Pan supports are dishwasher proof. When washing by hand, dry them carefully as enamelling may leave rough edges. Remove stubborn stains with a paste cleaner.

The Burners

Burner caps and crowns can be removed for cleaning. Wash them with hot soapy water and mild paste cleaner. A well-moistened soap-impregnated steel wool pad can be used cautiously for difficult marks. Ensure they are wiped dry with a soft cloth after cleaning.

Ignition Candle

The electric ignition uses a ceramic "candle" and a metal electrode. Keep these components clean to avoid difficult lighting and ensure burner crown holes are not obstructed.

Electrical Connections

⚠️ Any electrical work must be carried out by a qualified electrician or competent person, following current regulations.

THIS HOB MUST BE EARTHED. The manufacturer is not liable for damages resulting from failure to observe these safety measures.

This hob requires a 230-240V 50Hz AC electrical supply. Ensure the supply voltage matches the rating plate on the hob.

The hob is supplied with a 3-core flexible cord and a 3-amp plug. Use only a 3-amp ASTA approved (BS 1362) fuse if replacing it.

Replacing the Plug:

Wires in the mains lead are coloured as follows:

• Green and Yellow: Earth
• Blue: Neutral
• Brown: Live

Connect the wires to the corresponding terminals in the plug (marked 'E' or earth symbol for green/yellow, 'N' or black for blue, 'L' or red for brown).

Diagram Description (FO 0390): Shows the wiring connections for a plug: Green & Yellow wire to Earth terminal, Blue wire to Neutral terminal, Brown wire to Live terminal. Includes a 3 AMP FUSE and CORD CLAMP.

Important Notes:

• Ensure no wires are cut or frayed, and the cord clamp is secure over the outer sheath.
• A cut-off plug inserted into a 13-amp socket is a serious shock hazard; dispose of it safely.

Permanent Connection

For a permanent connection, install a double-pole switch between the hob and the mains supply. The switch must have a minimum gap of 3 mm between contacts and be suitable for the required load, complying with current electric regulations. The switch must not interrupt the earth cable.

Ensure the hob supply cord does not contact surfaces with temperatures higher than 50°C.

Fault Finding

Preliminary Electrical Systems Check

Follow this flowchart for electrical troubleshooting:

1. START: Isolate appliance and carry out: A: Earth Continuity check.
2. If Earth Continuity is satisfactory (less than 0.1 Ω), proceed. If not, check earth wires and contacts.
3. Has inlet fuse blown?
4. If NO: Inlet wiring is faulty. Rectify any fault.
5. If YES: Isolate appliance and carry out: B: Insulation check. Rectify any fault, including replacing fuses.

Detailed Checks:

• A. EARTH CONTINUITY CHECK: Appliance must be electrically disconnected. Meter set on Ω (Ohms) x 1 scale. Test leads from any appliance earth point to the earth pin on the plug. Resistance should be less than 0.1 Ω. Check all earth wires and contacts.
• B. INSULATION CHECK: Appliance electrically disconnected, all switches ON. Meter set on Ω (Ohms) x 1 scale. Test leads from L to N in the appliance terminal block. If meter reads close to 0, there is a short circuit. Meter set on Ω (Ohm) x 100 scale. Repeat test with leads from L to E. If meter reads less than ∞ (infinity), there is a fault.
• C. Polarity Check
• D. Resistance to Earth Check

NOTE: If a fuse has failed without an indicated fault, a detailed continuity check of each component is required to trace the fault. Visual inspection may reveal evidence of burning or arcing.

Ignition System / Gas Ignition

Troubleshooting flowchart for ignition issues:

• Ignitor does not spark:
• NO: Check plug top fuse and replace if necessary. Check polarity and earth continuity of supply point. Check earth continuity of appliance. Check continuity from 'N' on the mains connector block and 'O' on the ignitor unit. Check continuity from 'L' on the mains connector block and the taps ignition switches. Check continuity from ignition switches connector to ignitor unit.
• YES: Check gas supply at burner. Light burner manually. Check by-pass simmer adjustment. Check position of the electrode. Check continuity from the tip of each electrode to the terminals 1 to 4 on the ignitor unit. Check fitting of burners. Check for breaks in the insulation of the HT leads. Change the taps ignition switches. Change the ignitor unit.

Commissioning

After full installation, check the minimum flame setting:

• Turn the gas tap to MAX position and ignite.
• Set the gas tap to MIN flame position, then turn the control knob from MIN to MAX several times. If the flame is unstable or extinguishes, follow the procedure below.

Procedure:

• Re-ignite the burner and set to MIN.
• Remove the control knob.
• Use a thin-bladed screwdriver to turn the adjustment screw (see diagram) until the flame is steady and does not extinguish when the knob is turned from MIN to MAX. Repeat for all burners.
