C. Sidewalls/Surrounds
Adjacent combustible side walls must be located a minimum of 24 in. (610 mm) from the replace opening. See Figure 3.3.
If you are using a decorative surround constructed of combustible material, it must be located within the shaded area de-
ned in Figure 3.3. Short stub walls are also acceptable if they are contained within the shaded area.

quired clearances to combustibles around the replace must be adhered to. See Figure 3.2. Any framing across the top of
the replace must be above the level of the top standoffs.
