Raised and Flush Hearth Application:

If you would prefer to have a raised hearth, the Vent-Free

box can be raised to the desired height using wood studs or

concrete blocks.

When determining raised hearth height, be sure to

allow for the 3" thick firebox hearth and 1-1/2" thick firebrick

floor, in addition to the height of base platform.

For a "flush hearth" (fireplace floor flush with the room's

floor) the base plate can be omitted from the assembly and the

firebox walls built directly on the concrete support slab. The

fire brick floor of the firebox is then set directly to the concrete

support slab. This makes the fireplace finished fire brick floor

approximately one and one-half inches (1-1/2") above the top

of the concrete support slab.
