Non-Combustible Board Placement
Minimum Venting Requirements
Minimum permitted venting is shown below. The framing height to the center of
the thimble is 50”. Minimum venting must include a 12” vertical section and a
90 degree elbow which is then terminated horizontally. For a vertical
termination please follow the vent pipe manufacturer’s installation
instructions for vertical vent termination framing. A minimum of 1 in. (25 mm)
clearance on all sides of the vertical vent pipe must be maintained. For every
12” of horizontal run there must be a 1/4” of rise. 1” of clearance between
framing and venting must be maintained at all times. 2” above the venting and
3” above an elbow.
Fireplace Dimensions
Mantel Projections
Mantel graph dimensions are measured from the bottom of the fireplace, if you
wish to reference the mantel height from the tiling edge subtract 15 inches
(381mm) from the mantel height depicted on the graph. If you plan to install a
TV above your fireplace refer to the appropriate section of the owner’s manual
for available options.
It is acceptable to install a combustible mantel over top of the
noncombustible board. If you are activating the Cool Surface System you are
eligible to subtract 12” (305mm) from the mantel height shown in this diagram.
See page 6 for more details.

TV Installation Considerations
If you are planning to mount a TV above your fireplace some considerations must be made to ensure it is protected from the heat.
During testing temperatures did not exceed 121°F (49°C) midway up the front wall (see figures on right). There is no guarantee that these temperatures will not harm the longevity of your TV. Make sure to consult your TV manufacturer’s specifications to find the maximum allowable operating temperature. Since every home and installation is unique, temperatures should be verified at the time of install if possible. If desired, front wall temperatures can be lowered to 104°F (40°C) with the use of a mantle (see CSS TV clearances with Mantle figure). See revised mantle clearances chart above. A TV should not be installed if temperatures exceed the manufacturers maximum allowable temperature.
