All construction above the appliance must be self-supporting. DO NOT use the appliance for structural support. Secure the fi replace to the side framing members using the unit’s nailing fl anges — one top and bottom on each side of the fi replace front (See Figure 7). Use 8d nails or their equivalent.

Figure 7: Unit Secured to Framing by Nailing Flange Note: The nailing flanges, combustible members and screw heads located in areas directly adjacent to the nailing flanges, are EXEMPT from the 1/2” clearance to combustible requirements for the firebox outer wrapper. Combustible framing may be in direct contact with the nailing flanges and may be located closer than 1/2” from screw heads and the firebox wrapper in areas adjacent to the nailing flanges.
