THIS FIREPLACE IS NOT INTENDED TO BE
USED AS A SUBSTITUTE FOR A FURNACE TO
HEAT AN ENTIRE HOME. USE FOR SUPPLE-
MENTARY HEATING ONLY.
The FBK-200 Blower Kit is design certified by
Warnock Hersey for use with these appliances.
Always check local building codes. Installation
of the FBK-200 Blower Kit must comply with
local regulations as well as the National Electric
Code.

Combustion Air Kits

These appliances are equipped with an outside
(make-up) air door and integral actuator arm.
The appliance must be installed with an outside
air vent system ( Figure 41 ). These kits come
complete with detailed installation instructions
and all components necessary in completing a
combustion air vent system.

After completing the installation of the com-
bustion air vent system the actuator arm must
be put in service and tested to ensure proper
operation before completing any enclosure
around the firebox. Failure to do so may result
in extensive and costly rework.
Locate the actuator arm along the right side of
the appliance firebox opening and refer to
Figure 42 .

operation and freedom of movement. Return
the actuator arm to the locked position.

Gas Line Connection

Install only a ¹⁄₂" black iron pipe through fire-
place wall for connection to a decorative gas
appliance inside the firebox. Outside, the iron
pipe 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
connection with a match or open flame.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
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 requirements 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.
WARNING: THIS FIREPLACE HAS NOT
BEEN TESTED WITH AN UNVENTED GAS
LOG SET. TO REDUCE RISK OF FIRE OR
INJURY, DO NOT INSTALL AN UNVENTED
GAS LOG SET INTO THIS FIREPLACE.
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
sufficient diameter for the gas line to fit through.
The entire knockout does not have to be re-
moved. 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.
