These fine cracks can lead to small pieces of enamel breaking off,
resulting in rust spots. However, chips and fine cracks in the enamel
will not affect the performance of your barbecue.
No claim can be made on the warranty for enamel damage in the
cooking area after use.
5.7 Ventilation
The burners can only work properly if the heat they produce can also
escape. If this is not possible, the burners may not get enough oxygen.
This can cause an after-ignition, especially if the burners are in the
"HIGH" position. If this happens repeatedly, cracks may occur in the
burners. For this reason, there are ventilation openings
around the barbecue.
These allow hot air to escape. Always make sure that there is
sufficient open space around the cooking surface (the grills provide
sufficient space). Never cover the ventilation openings with foil or
other materials that obstruct the air flow. Ensure that the cooking
surface is NEVER covered completely, for example by a large pan or
with only grill flat tops.
5.8 Replacing the gas hose
The gas hose must be replaced every two years. Rubber gas hoses
can dry out which may result in gas leakage.
5.9 Burners
It is normal that rust forms on the burners (oxidation). Food residue
must be removed regularly. This can be done with a barbecue
cleaning brush. Burners must be removed for inspection and cleaning
periodically, especially after a period of non-use/storage. The burners
must be checked for their overall condition and to ensure that the
openings are not blocked. The burners can be cleaned by brushing
them. If you remove the burners, make sure that the gas tap and the
ignition electrode do not get damaged.
An opening has deliberately been made in the beginning of the burner,
to ensure that there is sufficient oxygen supply to create the right gas
mixture. As a result, you would be able to see a small opening, where
the gas tap connects to the burner. No gas will leak out here.
