INSTALLATION

BUILT-IN FIREPLACE
INSTALLATION
Built-in installation of this fireplace involves in-
stalling 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 40 and 41). 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 12. Follow the instructions be-
low to install the fireplace in this manner.
