BUILT-IN FIREPLACE
INSTALLATION
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 trim kit accessory is available (see
Accessories, page 40). 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 below to install the
fireplace in this manner.
