Built-In Fireplace Installation

INSTALLATION

Continued

Built-in installation of this fireplace involves installing fireplace into a framed-in enclosure. This makes the front of fireplace flush with wall. An optional brass trim kit accessory is available (see Accessories, pages 36 and 37). Brass trim will extend past sides of fireplace approximately 1/2 inch. This will cover the rough edges of the wall opening. If installing a built-in mantel above the fireplace, you must follow the clearances shown in Figure 10, page 10. Follow the instructions below to install the fireplace in this manner.
