1.
Construct the Fireplace Framing
1.
Frame the fireplace as illustrated in
Table 10
. All framing details must allow for a minimum clearance to combustible
framing members as shown in
Table 8
. Steel studs are strongly recommended where exposed to heat.
2.
Mount the fireplace on a fully supported base extending the full width and depth of the unit. If installed on
combustible materials, such as carpeting, vinyl tile, or combustible material other than wood flooring, the
appliance shall be installed on a metal or wood panel extending the full width and depth of the fireplace.
NOTE:
Headers may be in direct contact with the fireplace top standoff spacers when they are bent up vertically,
maintaining the 4 3/8” 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.
