An optional brass trim kit acces- sory is available (see Accessories, page 26). Brass trim will extend past sides of fireplace approximately 1/2 inch. This will cover the rough edges of the wall opening. If install- ing a built-in mantel above the fireplace you must follow the clearances shown in Figure 12, page 10. Follow the instructions below to install the fireplace in this manner.
