Mini trivet is included for RB-2CGN, RB-3CGN, if cooking with a 10cm & 12cm diameter of pan on
big burner, it’s recommended to use mini trivet.
When mini trivet is use make sure to turn down the flame and check that the flame do not spread
out to the sides of the pan.
Refer to the chart above and ensure that the pan diameter falls within the minimum and maximum
diametersgivenfortheburneryouareusing.Apanwhichistoosmallwillbeunstableonthepan
support. If the pan base diameter is too large, flames can spread out to the sides and damage or
burn the worktop, wall claddings or surrounding units and also parts of the hob. The manufacturer
cannot be held liable for this type of damage.
Select pans which are suitable for the burner they are to be used on. In general: use larger diameter
pans on the large burners, and smaller diameter pans on the small burners
Pans with thick bases are preferable as these distribute heat more evenly. With thin bases, there is a
danger of food overheating in places. Stir the food frequently.
Anyheat-resistantpanscanbeusedonagasburner.
When placing pans on the pan support(s) make sure you position them so that they cannot
tip up. Please note that it is not possible to prevent pans from wobbling very slightly.
