5. Place the storm collar over the chimney and flashing. Seal it around the chimney with silicone sealer (
DO
NOT use roofing tar
).
6. Fit the rain cap on the chimney. Secure it tightly in place.
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 9 and Figure 10 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 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). The support can be installed
anywhere practical along the vertical course of the chimney as long as it is above the offset.
