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 41
).
Note: The return elbow assembly performs the
same function as a stabilizer. Consider this
when determining the need for a stabilizer.

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.
OPTIONAL EQUIPMENT
CONSIDERATIONS
Blower Kits (Circulating Models Only)
Blower Kits model FBK-100/200 are available
for use with circulating models. The Blower
Kit can be installed prior to or after installation
of the fireplace.
When installing the FBK-100 Blower Kit, a
Blower Switch Kit (Model FUBSK) is required.
This switch kit allows for a unit mounted
blower switch to be used. The FUBSK is not
included and must be purchased separately.
The FBK-200 Blower Kit comes standard with
a wall mounted variable speed control switch.
Note: The fireplace must have provisions for
a wall mounted On/Off switch in order to install
the FBK-200.
THE FIREPLACE MUST BE WIRED TO THE
HOUSE ELECTRICAL SYSTEM AT THE TIME
OF INSTALLATION IN ORDER FOR THE OP-
TIONAL FANS TO OPERATE, (SEE
FIGURES
42 AND 43
).
Note: The utilization of fans will increase the
air flow around the firebox. However, only a
minimal increase in heat output should be
anticipated.
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.
INSTALLING OFFSETS
First, review the Offset Elevation Chart and
Figure 40
for reference.
