Frequently Asked Questions - MHG100SS MATRIX

How do I ignite the gas burners?

Press and turn the knob to the ignition position (usually a spark symbol) while holding down. The automatic ignition will click. Once lit, adjust the flame as needed. If it doesn't ignite, check that the gas supply is on and the burner cap is properly seated.

What should I do if the oven is not heating?

Ensure the oven thermostat is set to a temperature above room temperature and the oven door is closed. Check if the gas supply is active. If the oven has an electric ignition, verify that the power cord is plugged in and the circuit breaker is on. If the problem persists, the oven thermostat or gas valve may need replacement.

How do I clean the stainless steel surface?

Use a soft cloth with warm soapy water. For stubborn stains, use a mild stainless steel cleaner. Avoid abrasive pads or bleach. Always wipe in the direction of the grain to prevent scratches. Dry thoroughly to avoid water marks.

Can I use the oven with the door open?

No, the oven is designed to operate with the door closed. Opening the door during use can cause heat loss, uneven cooking, and increase the risk of burns. Only open for brief checks or when using the rotisserie function.

What type of gas can I use?

The cooker is factory-set for Natural Gas (G20) but can be converted to LPG (G30/G31) using a conversion kit. The injectors need to be changed. Consult the manual or a qualified technician for conversion.

How do I adjust the oven temperature?

Turn the oven thermostat knob to the desired temperature. The oven will heat until it reaches that temperature and then cycle to maintain it. Use an oven thermometer for accuracy. If the temperature is off, the thermostat may need calibration or replacement.

Why does the flame go out on the burner?

This is often due to a dirty or blocked burner head or thermocouple. Clean the burner cap and ports with a toothpick or soft brush. Ensure the thermocouple is not covered with residue. If the problem persists, the flame failure device may be faulty.

Is the cooker suitable for propane gas?

Yes, but it requires conversion. The cooker is initially for Natural Gas. For LPG (propane or butane), you must replace the burner injectors and adjust the regulator. Use only certified conversion kits and have it done by a qualified gas engineer.

How do I remove the oven door for cleaning?

Open the oven door fully. Locate the hinge locks (usually metal clips) and flip them to the locked position. Then close the door until it stops, lift up and gently pull out. Reverse the steps to refit. Note: the door is heavy.

What spare parts are available for this model?

Common spare parts include burner caps, trivets, oven racks, door glass, thermostat, ignition switches, and injectors. Contact Matrix customer service or authorized dealers. Provide the model number MHG100SS for accurate parts.

Gas burners:

Gas flow to the burners is controlled by the control knobs (5, 6, 7 and 8 on the diagram above). 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 hob can be set to the desired position by turning the control knob through the adjustment range in an anti-clockwise direction..

Igniting the Burners

The hob is fitted with a flame failure device. Flame failure devices operate by 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.

The hob is fitted with a flame failure device. Hold down the control knob for a few seconds after ignition to allow the safety device to detect that the burner is lit. Flame failure devices operate by shutting off the supply of gas to the burner in the event that the flame is extinguished accidentally.

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	12	14
Semi-Rapid	14	20
Rapid	18	24

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.

The enamelled parts of hobs are not suitable for cleaning in dishwashers; these should be washed by hand.

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 stand before repositioning the pan stands straight and level on the hob.
