3. If an extension cord is used, the marked electrical rating of the extension cord
must be at least 10 amps and 120 volts. The resulting extended cord must be

To reduce the risk of electric shock, this plug will fit in a polarized outlet only
one way. If the plug does not fit fully in the outlet, reverse the plug. If it still
does not fit, contact a qualified electrician. Do not modify the plug in any way.

centered on the warming plate or the water

lid is open.
