Your WESTINGHOUSE WHG644SA cooktop is fitted with mains-powered electronic ignition. Follow these steps to light a burner:

1. Ensure the power is connected and turned on.

2. Depress the control knob for the burner you wish to light.

3. While depressing the knob, turn it anticlockwise to the ‘High’ position.

4. Continue to push the knob down as far as possible for approximately 5 seconds. This allows the flame safeguard sensor to heat up.

5. Release the knob. The flame should remain lit.

6. If the flame goes out when the knob is released, depress the knob again, holding it down with slightly more force for the same length of time.

7. Adjust the flame height by turning the control knob between the ‘High’ and ‘Low’ positions.

Note: If a burner does not light within 5 seconds, turn the knob to the ‘Off’ position, allow the gas to disperse for a minute, and then try lighting it again.

In the absence of electrical power, you can light the burners directly with a hand-held ignition source.

Your cooktop has a choice of burners for different cooking needs:

• Small burner: For special low heat and slow cooking.

• Medium burner: For normal cooking and simmering.

• Large burner: For fast heating and large pots and pans.

• Wok burner: For very fast heating using a wok or a large pot or pan.

To conserve gas and cook efficiently, place the pan centrally over the burner. Adjust the flame so that it does not extend past the edge of the pan. A vigorous boil will not cook food any faster and will waste energy.

All common pots and pans (aluminium, stainless steel, cast iron, ceramic, etc.) may be used on your gas cooktop. Ensure that the pots or pans are steady and have flat bases to avoid dangerous spills and wasted energy.

A wok support is supplied for use when cooking with a round-bottom wok. The support is not necessary when cooking with a flat-bottom wok.

CAUTION: Never use asbestos mats, wire mats, grids, or aluminium foil as it can lead to overheating and cracked enamel, which will void the warranty. Woks should only be used on the wok burner with the wok support trivet.

Always ensure the appliance is turned off and cool before cleaning. Do not use steam cleaners or caustic-based cleaners.

Stainless Steel:

To prevent a yellowish discoloration, ensure any oil is cleaned off the hob before first use. To maintain the appearance of the stainless steel, clean it regularly. Wash with warm soapy water and rinse with clean water. For heavy soiling or discoloration, use a stainless steel cleaner. DO NOT use abrasive scourers or steel wool. When cleaning, be sure to follow the polish or brushing lines.

Enamel:

For persistent stains, you may need to rub with a nylon scourer or creamed powder cleansers. Do not use harsh abrasive cleaners, powder cleaners, steel wool, or wax polishes.

Trivets and Burners:

The burners and trivets are removable for easy cleaning. Ensure they are correctly seated when refitting. After cleaning or spillage, ensure burners are thoroughly dried. To clean flame ports, use a toothpick or brush to clear any blockages. Avoid scratching the polished outer surface of the burners. NOTE: DO NOT place burners in the dishwasher.

Ignition and Injector:

Gently clean the spark plug and flame safeguard sensor with a damp cloth to avoid lighting difficulties. Ensure the electrode is dry before use. For the injector, ensure it remains free of any foreign material. If necessary, use a thin piece of wire to clear the orifice.

The following tables provide the technical data for the various WESTINGHOUSE gas cooktop models. Height is the distance from the top of the kitchen bench to the bottom of the cooktop.

Models: WHG644SA, WHG646SA

Models: WHG756SA, WHG952SB, WHG956SA

The following table provides the required cutout dimensions (in mm) for installing the various WESTINGHOUSE cooktop models. Distances shown to adjacent walls/surfaces are for the distance to a combustible surface. If the surface is not combustible, the measurement can be smaller than that shown.

If the burner fails to light while the sparker is active, check the following possible causes and remedies:

• Knob not held down long enough: Repeat the lighting procedure, making sure to hold the knob down in the ‘High’ position for a full 5 seconds to engage the flame safeguard.

• Gas supply valve turned off: Ensure the gas supply to the appliance is turned on.

• Wrong knob turned: Make sure the control knob you are turning corresponds to the burner you wish to light.

• Port blockage in ignition area: Check that the burner ports in the ignition area are clean and dry.

• Ignition spark plugs wet or dirty: Carefully dry or clean the ignition spark plugs.

If you don’t hear or see a spark when the control knob is activated, check these potential issues:

• Electricity supply issue: Ensure the electricity supply is connected and switched on. Check your home’s circuit breakers or fuse box.

• Ignition spark plugs wet or dirty: The spark plugs may be damp or soiled. Carefully dry or clean the ignition spark plugs.

Uneven flames or flames that seem to lift off the burner can be caused by:

• Flame ports blocked or wet: Clean or dry the flame ports on the burner head to ensure they are clear of debris or moisture.

• Burner incorrectly fitted: Make sure the burner cap and crown are seated correctly on the burner base.

If the flame extinguishes after you release the control knob, it is likely a flame safeguard issue. Check the following:

• Knob not held down long enough: Repeat the lighting procedure. You must hold the knob fully depressed in the ‘High’ position for approximately 5 seconds after the flame ignites. This gives the flame safeguard sensor time to heat up and hold the gas valve open.

• Knob not set between ‘High’ and ‘Low’: The control knob MUST be set between these two positions for the burner to operate.

• Dirt or spillage on flame safeguard sensor: The sensor tip must be clean to function correctly. Clean the tip of the flame safeguard sensor.

If you are experiencing low heat and slow cooking times, the cause may be related to your cookware. Ensure you are using the correct size pot or pan for the burner you are using. A small pot on a large burner or a large pot on a small burner can be inefficient.

Overheating of the surrounding benchtop or the control knobs is typically caused by improper use of cookware. Check the following:

• Incorrect cooking pot or pan used: Ensure you are using the correct size cookware for the burner. A pot or pan that is too large for the burner can deflect heat outwards, causing the surrounding areas to overheat.

• Pot or pan not located on burner properly: Make sure the pot or pan is centrally located over the burner so that the flame heats the base of the pan directly and does not spill up the sides.

Discoloration of the stainless steel surface can occur if a pot or pan that is too large for the burner is used. The excessive heat can cause the steel to change color. To remedy this, clean the area with a suitable stainless steel cleaner.

Your appliance is supplied for Natural Gas use but includes a conversion kit for Universal LPG. Follow these steps for conversion:

1. Remove the hotplate trivets, burner caps, and burner crowns to access the injectors. Replace the factory-fitted NG injectors with the appropriate LPG injectors from the kit. The injector size is stamped on its side. Refer to the injector orifice table for sizes.

2. Unscrew the top hat nut from the regulator. The nut and control pressure spring assembly will disengage together.

3. Unscrew the threaded pin from the top hat nut.

4. Turn the threaded pin upside down so the spring is free, and screw the pin back into the top hat nut until it is firm.

5. Refit the top hat nut assembly to the regulator, ensuring it is fully screwed down. The regulator is now set for LPG.

6. Turn on the gas supply and check for leaks at each new connection using soapy water.

7. Confirm the regulator’s operation by checking the outlet pressure with a manometer at the pressure test point. For LPG, the nominal outlet pressure should be 2.60kPa (±0.52kPa).

8. If the regulator is not performing correctly, check the inlet pressure (should be 2.75 – 7.00kPa), ensure the insert is fitted correctly, the turret screw is fully down, and the regulator is oriented correctly.

9. Adjust the minimum flame setting. One by one, turn each knob to the minimum position. Access the bypass screw by removing the knob. Screw in the bypass screw until a small, stable flame is achieved. Turn the knob to maximum and then back to minimum to confirm the setting is correct.

10. Attach the LPG sticker (included in the kit) to the cooktop near the gas supply inlet, covering the original Natural Gas label.

The following table shows the correct injector sizes and gas consumption for NG and LPG:
