Construct the Fireplace Framing
1.
1. Frame the fireplace as illustrated in Table 10. For corner framing installations, use Table 11. All framing details
must allow for a minimum clearance to combustible framing members as shown in Table 8.
2. If the fireplace is to be elevated above floor level, a solid continuous platform must be constructed below the fireplace.
NOTE: Headers may be in direct contact with the fireplace top standoff spacers when they are bent up vertically,
maintaining the 4" clearance to the fireplace top, but must not be supported by them or notched to fit around them.
All construction above the fireplace must be self-supporting. DO NOT use the fireplace for structural support.
