The appliance switches itself off automatically after 2 hours.
Metal components have a protective coating which may give
off a slight smell when heated up for the first time.
The smell and any vapours will dissipate after a short time,
and do not indicate a faulty connection or appliance.
Ensure that the kitchen is well ventilated whilst the appliance
is being heated up for the first time.
