OFFSET CHIMNEY
An elbow may be installed directly on top of the fireplace if required. See the detailed offset charts in the EXCEL
chimney installation manual. Use the offset option if you need to clear a joist or pass around a cupboard. See Figure
12 and Figure 13 for examples.
•
Maximum offset angle:
•
In
USA
: 30°;
•
In
Canada
: 45°.
•
Maximum number of elbows: 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 required elbow. Turn it in the desired direction, and fasten it to the other section with 3 metal screws
at the joints.
2. Install enough lengths to obtain the desired offset. Secure each joint with 3 metal screws.
3. Use another elbow to return the chimney to the vertical direction.
4. Install 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).

You can also go through the wall at an angle starting directly at the fireplace as depicted in Figure 13. An angled
wall insulated radiation shield (XM-7EWRSI30 or XM-7EWRSI45) must be used wherever the chimney passed
