Use the offset option if you need to clear a joist or pass
around a cupboard.
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 direc-
tion, 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 verti-
cal direction.
4. Install a roof support, an offset support, or a wall sup-
port after the return elbow, to support the weight of
the flue (elbows are not designed to support a flue
above an offset). Refer to the Excel chimney instal-
lation manual for more information.
