HIMNEY
An elbow may be installed directly on top of the fireplace if required. Use the 12" RIS
offset charts in the RIS chimney installation manual which can also be found at:
www.icc-rsf.com/en/model-ris-offset-tables. Use the offset option if you need to clear a
joist or pass around a cupboard. See Figure 14 and Figure 15 for example.
The maximum offset angle:
•
In USA: 30°;
•
In Canada: 45°.
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:
Install the elbow. Turn it in the desired direction, and fasten it to the other section 1.
with 4 metal screws at the joints.
Install enough lengths to obtain the desired offset. Secure each joint with 4 metal 2.
screws.
Use another elbow to return the chimney to the vertical direction. Again fasten it to 3.
the other section with 4 metal screws at the joints.
Install a roof support, a wall support, or an offset support above each offset to 4.
support the weight of the chimney (elbows are not designed to support the chimney
above an offset).
