5.7 Ventilation
The burners can only function properly if the heat they produce can escape as
well. If this is not possible, then the burners may not get enough oxygen, which
may cause backfiring, especially if the burners are set to “HIGH”. If this happens
regularly, it may cause the burners to develop cracks. For this reason, there are
ventilation openings around the barbecue. These allow the hot air to escape.
Always ensure that there is sufficient space around the cooking area (the racks
will allow sufficient space). Never cover the ventilation openings with aluminium
foil or other materials that can impede the airflow. NEVER allow the cooking
surface to be completely covered, for instance by a large pan or by completely
filling it with grill trays.
5.8 Replacing the gas hose
The gas hose should be replaced every two years. Rubber gas hoses can dry out
which may result in gas leaks.
5.9 Burners
It is normal for rust (oxidation) to form around the burners. Food remnants must
be removed regularly. This can be done by means of a barbecue cleaning brush.
Burners must periodically be removed for inspection and cleaning, in particular
after a period of non-use/storage. The burners must be checked for their general
condition and to ensure that the openings are not blocked. The burners can be
cleaned with the use of a brush. When removing the burners, make sure that you do
not damage the gas valve and the ignition electrode.
An opening has been placed intentionally in the first part of the burner to ensure that
enough oxygen can be supplied to form a flammable mixture. This means you will
see a small opening, just where the gas valve connects to the burner. No gas will
leak from this.
5.10 Spiders and insects
Spiders and insects can make their nest inside the burners of the barbecue, which
may cause gas to flow from the front of the burner. This is a dangerous situation
that can cause a fire behind the operation panel. This will damage the barbecue,
which will then no longer be safe to use. Therefore, we recommend that you check
the barbecue at least once a year for spiders, insects and nests (particularly after
long storage periods). You can do this by dismantling the burner tubes and blowing
through them or brushing them clean.
