BUILT-IN FIREPLACE

INSTALLATION

Built-in installation of this fireplace involves installing fireplace into a framed-in enclo- sure. This makes the front of fireplace flush with wall. An optional brass trim kit acces- sory is available (see Accessories, page 27). 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 11, page 10. Follow the instructions below to install the fireplace in this manner.

Height	26"	26 7/8"
Front Width	26 3/4"	26 7/8"
Depth	9 1/2"	10 1/2"
Bottom	3/4"	3/4"

1.Frame in rough opening. Use dimen- sions shown in Figure 8 for the rough opening.

If installing in a corner, use dimensions shown in Figure 9 for the rough open- ing. The height is 26 7/8" which is the same as the wall opening above.

2.If installing GA3400(T) blower acces- sory, do so at this time. See Installing Blower Accessory GA3400T, page 11.

Note: If not installing blower acces- sory, you may wish to run electrical wiring to your fireplace for future blower installation (see Accessories, page 27) Use only approved three-wire electrical wiring.

Note: A qualified installer should make all electrical connections.

3.Install gas piping to fireplace location. This installation includes an approved flexible gas line (if allowed by local codes) after the manual shutoff valve. The flexible gas line must be the last item installed on the gas piping.
