INSTALLING OFFSETS
First, review the Offset Elevation Chart and
Figure 38 for reference.
Step 1. Determine the offset distance where
chimney is to pass through the first ceiling-
dimension "A." To find this point on your ceil-
ing, first determine the center point for a verti-
cal chimney following the instructions for ver-
tical installation.
Measure height to the ceiling from the top of
fireplace-dimension "B." Use the appropriate
Offset Elevation Chart to find dimension "A."
Mark point where you will drive your nail to
show the center point for your offset ceiling cut.
Step 2. Proceed by using the Straight Up Instal-
lation Instructions for cutting and framing ceil-
ing and roof openings.
Note: See Framing and Dimension Chart for the
sizes of the ceiling and roof openings. The size
of the roof opening varies with the degree of
pitch of the roof.
Offset Elbow Assembly
Offset elbows install the same as chimney
sections. First, snap the inner section INTO the
preceding inner section of flue. Check connec-
tion by pulling up slightly to ensure a tight fit.
Next, the outer sections snap lock OVER the
preceding outer section of chimney. Again,
check outer section by pulling up slightly to
ensure proper connection is made.
Return Elbow Assembly
Return elbows install the same way as round
terminations and stabilizers:
Step 1. Hold return elbow over top of last
chimney section.
Step 2. Center inner slip section into inner flue
pipe-slip down.
Step 3. Center outer-locking section over outer
chimney pipe. Push down until locking joint has
firmly engaged.
Step 4. Pull up slightly on return elbow to
ensure locking joint has firmly engaged.
Step 5. Secure support straps to framing
members by nailing under tension in sheer
( Figure 39 ).
Figure 39
Note: The return elbow assembly performs
the same function as a stabilizer. Consider this
when determining the need for a stabilizer.
Note: Do not apply excessive pressure to any
subsequent chimney section following return
elbow assembly when installing. Ensure that
each subsequent chimney section is securely
attached by testing as noted above.
Combustion Air Kits
These appliances are equipped with an outside
(make-up) air door and integral actuator arm.
If the appliance is to be installed with an
outside air vent system, use only Models FAOK-
4 or FAOK-4LD Combustion Air Kits. 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 op-
tional combustion 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.
The control lever that operates the outside
combustion air valve has been pre-installed on
your fireplace. A coverplate has been mounted
over this control lever only if the outside air kit
has not been attached. The control lever is
located on the closed end of the fireplace open-
ing behind the screen. To open the air damper,
turn the lever handle 1/2 turn counter clockwise
(or until lever can be moved upward), then re-
tighten at desired open position. To close
damper, reverse procedure ( see Figure 40 ).
Operate the actuator through several cycles
including the "lock position. Ensuring proper
operation and freedom of movement. Return
the actuator arm to the locked position.

Gas Line Connection
Install a
" (13 mm) gas supply line through
fireplace wall for connection to a decorative
gas appliance inside the firebox. Outside, the
gas supply line must connect to a gas shut-off
valve usually recessed flush into the wall or
floor. The valve should be controlled by a
removable valve key for safety.
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.
Always plumb gas line installation per local
codes. Check all connections and test for gas
leaks, using a gas leak test solution (also
referred to as bubble leak solution).
Note: Using a soapy water solution (50% dish
soap, 50% water) is an effective leak test
solution but it is not recommended, because
the soap residue that is left on the pipes/
fittings can result in corrosion over time. Never
use an open flame to check for leaks.
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.
