Raised and Flush Hearth Application:
 For a “ush hearth” the IBV must be built upon a
concrete (noncombustible) support slab that has no wood
underpinnings. (Figure 5) For a “ush hearth” application
the IBV three inch (3”) thick base plate is omitted from the
assembly.Therebrickwillthenbemortaredontheconcrete
slab and the noncombustible hearth material will butt tight up
against it.
 For a “raised hearth”(oor of thereplace elevated
above the room’s oor) the IBV base plate can be set on a
structurally sound built up platform that is built to the desired
nishedraisedhearthheight.
When calculating raised hearth height be sure to allow
for the three inch (3”) thick base plate plus the one and one-half
inch(11/2”)thickrebrickoorinadditiontotheheightof
theeldconstructedraisedplatform.(Figure6)
