Rebate mantels require that a 'chase' be constructed of 2x4's and drywall to accommodate the depth of the firebox. A cabinet mantel is deep enough to accommodate the firebox, eliminating the need of a chase.

All our mantels are designed with some depth to them, which gives any mantel more pleasing lines. However, this requires that the firebox that they are being installed with be located ahead of the drywall, whether they are used with a rebate or a cabinet mantel. Please consult the installation manual for the specifics of how far forward of the drywall the firebox must be installed.

A similar approach is required when using a hearth. The firebox must be installed at a certain height off the finished floor, in order to allow the hearth to be properly located. Again, please consult the installation manual for these specifics.
