HEARTH EXTENSION

While a hearth extension is not required for this appliance, one is recommended
for aesthetic reasons. The installation of a 1" (25mm) hearth extension will
conceal the 1" (25mm) gap under the appliance. The hearth extension must
not be any more than 1" (25mm) above the bottom of the appliance.
If thicker, the appliance must be raised up accordingly.
NOTE: Hearth extensions thicker than 1" (25mm) will
interfere with the safety barrier assembly.
