Operation Manual

Maintenance
• When the ceramic burner has been used very often, discolorations on the top can occur. This
is normal and does not harm to the quality of the product.
• Do not use an abrasive product for cleaning the insert. Clean the surfaces with a moist piece
of cloth or a non-abrasive stainless steel cleanser.
• Glass screens can be cleaned with a ceramic cook top cleaner.
