2. From below, install a radiation shield in each floor through which the chimney passes. At the attic level, install
a radiation shield and a storm collar as shown in Figure 14.
WARNING: A RADIATION SHIELD MUST BE INSTALLED AT EACH FLOOR WHERE THE CHIMNEY
PASSES THROUGH.
3. Remove the flue adapter from the fireplace, put
the screws aside. Install the flue adapter on the
first chimney length and secure it with the screws
provided. Reinstall the flue adapter on the
fireplace and secure it with the screws you have
put aside earlier. 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. Put the roof flashing into place. 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.
If the chimney is enclosed to the roof:
In
USA
: use a vented flashing;
In
Canada
: use a vented flashing, or a roof
radiation shield with a regular flashing.
In the case of the regular flashing with a
roof radiation shield, the roof radiation
shield must be installed so it extends 1"
above the roof line.
5. Place the storm collar over the chimney and flashing. Seal it around
the chimney with silicone sealer (
DO NOT use roofing tar
).
If a vented flashing is used, the bottom of the storm collar should be
aligned with the bottom of the openings in the flashing as shown in
Figure 15.
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 16 and Figure 17 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.
