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.

2. If installing GA3450TA blower accessory, do
so at this time. Follow instructions included
with blower accessory.
Note:
If not installing blower accessory, you
may wish to run electrical wiring to your fire-
place for future blower installation (see Ac-
cessories, pages 40 and 41). Use only ap-
proved three-wire electrical wiring.
WARNING: If pre-wiring, do
not connect wiring to any elec-
trical source at this time.
Install fireplace electrical outlet
and connect wiring to outlet be-
fore connecting to electrical
source. The fireplace electrical
outlet is included with the
GA3450TA blower accessory.
Only use the fireplace electrical
outlet supplied with the
GA3450TA blower accessory.
Note:
A qualified installer should make all elec-
trical connections.
3. Install gas piping to fireplace location. This
installation includes an approved flexible gas
line (if allowed by local codes) after the equip-
ment shutoff valve. The flexible gas line must
be the last item installed on the gas piping.
4. If you have not installed hood, follow instruc-
tions on page 6.
5. Carefully set fireplace in front of rough open-
ing with back of fireplace inside wall opening.

lator. See Connecting Equipment Shutoff Valve

pliers (see Figure 9).

wood screws through holes in nailing flange.
