Cleaning the cooktop
Before using for the first time clean the
appliance as follows:
^ Wash the removable parts of the gas
burner in a mild solution of warm
water and liquid dish soap.
^ Wipe dry and reassemble them in the
proper order (see the "Cleaning and
Care" section).
^ Wipe the cooktop surface with a
damp cloth and dry thoroughly.
Metal components have a protective
coating which may give off a slight odor
the first time your new appliance is
heated.
The harmless odor will dissipate after a
short time and does not indicate a
faulty connection or appliance defect.
