**Max. mantle depth is 10" (254mm).
Thermal fl oor protection is not required if the unit is raised 3.5" minimum (measured from the bottom of the stove). However, standard ember fl oor protec- tion is required. It will need to be a
If the unit is not raised, thermal fl oor protection required is 18" (450 mm) in the US and Canada.
