CHIMNEY INSTALLATION
NOTE: The clearance between the chimney and com-
bustible material must be 2" or more. DO NOT fill this area
with insulation.
1. Cut and frame the required holes in the floor, ceiling and
roof where the chimney will pass through. Use a plumb
bob.
The rough opening in the framing size is 13 1/4”
square.
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 6).
3. Place the first chimney length on the fireplace. Secure
the chimney length to the fireplace with the three screws
provided.
The chimney must extend at least 3 ft. above its point of
contact with the roof and at least 2 ft. higher than any wall,
roof, or building within 10 ft. of it.
NOTE: If the chimney is higher than 5 ft. 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:
-USA:
use a vented flashing.
-CANADA:
use a vented flashing or a
roof radiation shield (ERRS)
and a regular flashing.
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.
7. Read the EXCEL Chimney installation manual concern-
ing requirements for supports, bracing, anchors, etc.
8. The maximum height of chimney that can be supported
by the top of the fireplace is 18 feet.
MASONRY CHIMNEY
WARNING: When contemplating using an existing
chimney, it must first be thoroughly inspected by an
authority having jurisdiction to determine the follow-
ing:
1. It is a well constructed, lined masonry chimney, fully in
accordance with Local Building Codes and the National
Building Code of Canada NBCC 9.21 or NFPA 211.
2. It has been thoroughly cleaned of any soot or creosote
residue and inspected to determine that it is in good con-
dition.
3. There is no attic insulation of any type in contact with the
chimney and no insulation stuffed in around the chimney
at any point, for any reason.
4. There is, as per NBCC 9.21 or NFPA 211, the necessary
air space clearance at all points around the chimney
from floor to roof flashing. If the chimney is enclosed in
drywall, openings will probably be required in order to
verify clearances at all points.
5. Chimney will be used only for the fireplace and may not
be used to vent a furnace, water heater or any other
appliance.
