Wood burning stove - hearth thickness

[mattrgee]

Hi,

The wood burning stove we are looking at is certified for a 12mm hearth and will be installed in a fireplace recess. Consequently, is a full depth constructional hearth also required within and extending in front of the fireplace recess?

Thanks.
