OPEL 2000

OFFSET CHIMNEY
Maximum offset angle:
45°
Maximum number of elbows:
4, resulting in two
(2) offsets.
An elbow may be installed directly on top of the fire-
place if required.
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 the 3 metal
screws provided at the joint.
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, or an offset support at each
offset to support the weight of the flue (elbows are not
designed to support a flue above an offset).
FRAMING IN
The enclosure walls can be framed with any suitable
materials (2x4 or 2x6 studs, plywood, gypsum board,
etc.). Because of the high heat output potential of the
OPEL 2000, combustible material must NOT go closer
to the fireplace than the standoffs, top, back and sides.
If you like, framing can be set back to allow the facing to
be flush with the front of the fireplace.
