Offset Chimney - RSF Woodburning Fireplaces FOCUS 320 SBR Owner's Manual

3. Place the first length of chimney on the fireplace.
Secure the chimney length to the fireplace with
the three screws provided. Assemble the rest of
the chimney.
The chimney must extend at least 3' above its
point of contact with the roof and at least 2' higher
than any wall, roof, or building within 10' of it. If
the chimney is higher than 5' above the roof, it
must be secured using a roof brace.
4. At the roof, install a roof radiation shield (XM-
7ERRS). The roof radiation shield must be
installed so it extends 1" above the roof line.
5. Put the roof flashing into place.
•
If the chimney is enclosed to the roof: use
a vented flashing .
•
If the chimney is not enclosed to the roof:
use a regular flashing.
6. Seal the joint between the roof and the flashing
with roofing tar. For sloping roofs, place the
flashing under the upper shingles and on top of
the lower shingles. Nail the flashing to the roof
using roofing nails.
7. Place the storm collar over the chimney and
flashing. Seal it around the chimney with silicone
sealer (DO NOT use roofing tar).
8. 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
8 and Figure 9 for examples.
•
Maximum offset angle:
•
In USA: 30°
•
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 chimney length with the three
metal screws provided at the joints.
2. Install enough lengths to obtain the desired offset. Secure each joint with three metal screws. Refer to the offset
charts provided with the EXCEL chimney installation manual for exact offset dimensions.
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).
