*This dimension can be reduced to 41" (1041 mm). This results in 0" (0mm) clear-

Position the fireplace within the framing. When
required, the flanges may be bent 90 degrees by
hand or with the assistance of a hammer. Use

ances of framing members to cabinet parts in
the nailing flange area. The nailing flange itself
is exempt from these clearances.
