Outside air drawn into the fireplace supplies air
to the fire for combustion. Only one combus-
tion air duct on the left side of the fireplace is
necessary if installed ( Figure 41 ).
Provision

Air

Figure 41
If additional length of duct is necessary, pur-
chase locally available Type 0 or 1 metallic duct.
The duct may extend up to 50' in any direction.
Note: When installing the air duct vertically, DO
NOT terminate the duct closer than 3' below the
chimney top.
There is a one hand operated shut-off valve
located in the left side of the fireplace opening
behind the screen. To open, pull out all the way.
The combustion air damper should be fully
open when the fireplace is in use and fully
closed when the fireplace is not in operation to
prevent outside air from entering your home.
CAUTION: NEVER LOCATE INLET WHERE IT
CAN BE BLOCKED BY SHRUBS, SNOW DRIFTS,
ETC. NEVER LOCATE INLET IN A GARAGE OR
ANY AREA WHERE THERE IS ANOTHER FUEL-
BURNING APPLIANCE OR PRODUCT EMIT-
TING COMBUSTIBLE GASES SUCH A PAINT,
GASOLINE, ETC. IN COLD CLIMATES IT IS
RECOMMENDED THAT THE COMBUSTION AIR
DUCT BE INSULATED.
Outside combustion air ducting may be run
upwards or vertically through framing and ceil-
ing joists, with the hood installed through an
outside wall and 3' below the termination. Duct-
ing may also be run downward through floor
joists and under the home to a ventilated crawl-
space not considered part of the living area of
the home.
Note: Do not terminate combustion air kit in
attic space under any circumstances.

Gas Line Connection

Install a " gas supply line through fireplace
wall for connection to a decorative gas appli-
ance inside the firebox. Outside, the gas supply
line connects to a gas shut-off valve recessed
flush into the wall or floor. The valve should be
controlled by a removable valve key for safety.
Always plumb gas line installation per local
codes. Check all connections with soap suds;
leaks will bubble. Never test any gas line con-
nection with a match or open flame.
This provision is intended for connection to a
decorative gas appliance incorporating an au-
tomatic shut-off device and complying with the
Standard for Decorative Gas Appliances for
installation in vented fireplaces, ANSI Z21.60
(1991) or American Gas Association draft re-
quirements for Gas-Fired Log Lighters for Wood
Burning Fireplaces, Draft No. 4 dated August,
1993. Install in accordance with the National
Fuel Gas Code, ANSI Z223.1. This complies
with the revised U.L. 127 standard.

Vent Free Appliances

These fireplaces have been tested and ap-
proved to ANSI/IAS/AGA Z21.11.2 for use with
unvented gas appliances and comply with the
standard for Factory-Built fireplaces, UL 127,
when installed with unvented gas log sets.
Special instructions with regards to mantle
installations must be taken into consideration
when installing such appliances.
These fireplaces have been tested for use
with any unvented log set having a maximum
rating of 26,000 BTU (38 Models) and 32,000
BTU (43 Models). The minimum mantle con-
figuration for these log sets are outlined in
Figure 42 .
Log sets with 40,000 BTU may be installed
provided that no combustible mantle projec-
tions are placed lower than 18 inches from the
fireplace opening.
These fireplaces have been marked with a
maximum rating of 26,000 BTU (38 Models)
and 32,000 BTU (43 Models) to assure that
homeowners do not exceed the allowable lim-
its for all allowed installations of mantles. That
limit may be increased to 40,000 BTU, pro-
vided that the mantle installed complies with
the 18-inch limitation and a copy of these
instructions are available.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
NEVER INSTALL AN UNVENTED GAS LOG SET
WITH A BTU RATING GREATER THAN 26,000
BTU (38 MODELS) AND 32,000 BTU (43 MOD-
ELS) IF THE COMBUSTIBLE MANTLE PRO-
JECTIONS ARE LOWER THAN 18 INCHES
ABOVE THE FIREPLACE OPENING.
CAUTION: WHEN USING THE DECORATIVE
GAS APPLIANCE, THE FIREPLACE DAMPER
MUST BE SET IN THE FULLY OPEN POSITION.
CAUTION: PLUMBING CONNECTIONS SHOULD
ONLY BE PERFORMED BY A QUALIFIED, LI-
CENSED PLUMBER. MAIN GAS SUPPLY MUST
BE OFF WHEN PLUMBING GAS LINE TO FIRE-
PLACE OR PERFORMING SERVICE.
If you're installing a gas line, connect it before
the fireplace is framed and enclosed in the
finished wall. The gas knockout is determined
by the indentation located at the bottom and
slightly off center in the side refractories. THE
KNOCKOUT IS ALWAYS REMOVED FROM IN-
SIDE THE FIREPLACE. DO NOT REMOVE THE
KNOCKOUT UNLESS YOU ARE INSTALLING A
GAS LINE. If removal is attempted from the
outer wrapper, side refractory damage may
occur. With a medium-sized hammer, lightly
tap the surface of the indentation. The refrac-
tory material is very thin in this area and is easily
removed. Once a small hole has been made,
continue tapping until you have reached suffi-
cient diameter for the gas line to fit through. The
entire knockout does not have to be removed.
Remove insulation in the gas line channel.
IMPORTANT: REPACK INSULATION MATERIAL
IN SQUARE HOLE AROUND GAS LINE, INTE-
RIOR AND EXTERIOR OF FIREPLACE, TO SEAL.

Glass Doors

If glass doors are to be installed on these
fireplaces, refer to specific installation instruc-
tions packed with the glass doors. Use only the
doors that are listed for use with these fire-
places. Use of other non-listed glass door on
these fireplaces may constitute a potential fire
hazard and is not recommended.
CAUTION: CERTAIN GLASS DOORS OVERLAP
THE BLACK METAL FACING OF THE FIRE-
PLACE. IF THE FIREPLACE HAS BEEN FACED
WITH NONCOMBUSTIBLE MATERIALS, THERE
MIGHT NOT BE SUFFICIENT CLEARANCE TO
INSTALL THE GLASS DOORS OF YOUR
CHOICE. ENSURE ADEQUATE CLEARANCE IS
MAINTAINED AT ALL TIMES SO AS NOT TO
INTERFERE WITH THE INSTALLATION AND
OPERATION OF GLASS DOORS.
