I plan to install a zero clearance woodburing box into my living room. I'd like to make a wood surround and mantle as well. Is the unit really "zero clearance", that is, can I put combustables right up to the metal side edges of the unit? Does anyone know what, if any, additional clearance is needed for an overhanging mantle (perhaps a 4-5 inch thick beam)?The box is a Heatilator unit.
