An elbow may be installed directly on top of the fireplace if required. Use
the offset option if you need to clear a joist or pass around a cupboard. See
following Diagrams for example.
- In
USA
: 30° Maximum
- In
Canada
: 45° Maximum
The maximum number of elbows per system is four, resulting in two offsets
and returns.
Install the fireplace and chimney as described earlier. When you require an
elbow, proceed as follows:
1. Install the elbow. Turn it in the desired direction, and fasten it to the other
section with 4 metal screws at the joints.
2. Install enough lengths to obtain the desired offset. Secure each joint with
4 metal screws.
3. Use another elbow to return the chimney to the vertical direction. Again
fasten it to the other section with 4 metal screws at the joints.
4. Install a roof support, a wall support, or an offset support above each
offset to support the weight of the chimney (elbows are not designed to
support the chimney above an offset).
NOTE: 'Through the wall offset' installation requires installa-
tion of the gravity kit along with chase ventilation grills.
Failure to do so could result in severe overheating of the fireplace
chase cavity.

chimney installed on the fireplace before the first elbow.
Offset Chimney Installation Example
Note: Nailing strips differ than shown in diagram
Offset Chimney Through a Wall Example
You can also go through a wall at an angle starting directly at the fireplace as
depicted in Diagram below. An angled wall insulated radiation shield must be
used wherever the chimney passes through an exterior wall.
Make sure to have enough ceiling height for your installation. If the ceiling height
is too low for the planned installation you may want to consider installing the
fireplace in an outside chase.
Refer to the angled wall insulated radiation shield installation sheets for detailed
installation instructions.
