Elbows may be used in an interior
installation to provide an offset in order to avoid cutting of joists and
to clear other obstructions. Each Elbow support will support 15 feet
of chimney and the maximum length of chimney allowed between
elbows is 6 feet.
Forty-five-degrees (45°) Elbows may be used only with oil or gas
appliances. See Chart 1 - Offset Chimney Installation on page 15 in
these instructions for details.
The female end of Elbows are not embossed. This allows 360° rotation
and ensures the proper alignment of the chimney system is
maintained. Locking Bands must be installed at all chimney joints
forming an offset.
Install the insulated offset Elbow on the vertical chimney Length and
position the elbow in the required direction. Fasten the Elbow to the
chimney Length with the supplied Locking Band.
Place the required offset chimney Length(s) as per the Offset Chart
for appropriate Length(s). Turn it clockwise to lock it in place and
fasten in place with the supplied Locking Band.
Install the remaining Offset Elbow to turn the chimney back to the
vertical position and fasten in place with the supplied Locking Band.
During installation provide supplementary support for the offset
section to avoid undue stress on connected elbows.
Install an Elbow Support on the first Length just above the highest
Elbow. Attach the Support Band to the chimney with 4 of the nuts
and bolts, and then install the four stainless steel sheet metal screws
through the pre-punched holes. Attach the Support Straps to the
Support Band assembly and nail the Support Straps to the framing
using 6d (2”) nails or #8 x 1-1/2" wood screws (see figure 9).

FIRESTOP JOIST SHIELD
A Firestop Joist Shield (FRS) must be installed where the
chimney passes from one living space to another living space, as
shown in figure 8. It is designed to provide proper firestopping
between floors and to keep direct radiation from the chimney away
from the joist framing.

When the chimney is enclosed in the attic area, a Firestop Joist Shield
(FRS) must be installed at the ceiling level. If the base of the Firestop
Joist Shield (FRS) does not fit flush with the ceiling frame, measure
the distance that the base is sitting below the framing and trim that
amount off of the top of the FRS before securing into place.
Install the Firestop Joist Shield (FRS) from below the joist framing and
nail in place using 1" spiral nails. Ensure no insulation is within the
2" air space clearance around the chimney. This includes the air
spaces between the Firestop Joist Shield (FRS) and the joist framing.
Never install an Elbow in a joist area. Chimney Lengths
must pass vertically through framed joist areas.
