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 38 ).

INSTALLING OFFSETS

First, review the Offset Elevation Chart and
Figure 37 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
ceiling, first determine the center point for a
vertical chimney following the instructions for
vertical 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

Installation Instructions for cutting and fram-
ing ceiling 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.

Figure 38

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.

OPTIONAL EQUIPMENT
CONSIDERATIONS

Blower Kit

A Blower Kit model BFK36 is available for use
with these models.  The Blower Kit has been
installed in this fireplace at the factory.

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.

The BFK36 Blower Kit is design certified by
Omni-Test Laboratories for use with these
appliances.
