2. Framing the Fireplace
The T4200 fireplace will fit a framed opening of 52" wide x 43
27¾".
Figure 5 shows a typical framing (using 2 x 4 lumber) of the fireplace, assuming combustible materials are used. All
required clearances to combustibles around the fireplace must be adhered to. Any framing across the top of the
fireplace must be above the level of the top standoffs. Chimney sections at any level require a 2" minimum air
space clearance between the framing and chimney section.
Do not apply combustible finishing materials over any part of the black face of this fireplace or a structure fire
may result. The black metal fireplace front may only be covered with noncombustible materials such as ce-
ramic tile, brick, or stone. Do not cover or block any cooling air slots. Do not cover any portion of the opening
to the fireplace that would prevent the installation of an authorized glass door.
3. Sidewalls/Surrounds
Adjacent combustible side walls must be located a minimum of 24" from the fireplace opening. See Figure 6. If you
are using a decorative surround constructed of combustible material, it must be located within the shaded area
defined in Figure 6. Short stub walls are also acceptable if they are contained within the shaded area.
