IF THE CHIMNEY IS
UNLINED:
A stainless steel
liner listed to either
Standard ULC-
S640M, ULC-S639 in
Canada or UL-1777
in the USA: Liners
for New Masonry
Chimneys, may be
used to connect
the fireplace to the
chimney. The liner
must be continuous
from the fireplace
to the chimney cap
and be installed only
per manufacturers
instructions.
Figure 19. In both
cases, the chimney
structure must be supported by angle iron anchored into the masonry
walls. Figures 19 & 20. The allowable masonry used in chimney
construction is 3-1/2" brick, solidly mortared and fully encasing the
fl ue. Ensure there are no leaks.
In no case is the masonry enclosure to be supported by the NZ-26
fi replace. Allow a 1" (one inch) air cavity for expansion.
Remove the nails from the shingles above and to the sides of the
chimney. Place the fl ashing over the chimney pipe and slide under-
neath the sides and upper edge of the shingles. Ensure that the chim-
ney pipe is properly centered within the fl ashing, giving a 3/4" margin
all around. Fasten to the roof on the top and sides. DO NOT NAIL
through the lower portion of the fl ashing. Make weather-tight by seal-
ing with caulking. Where possible, cover the sides and top edges of
the fl ashing with roofi ng material. Apply waterproof caulking, provided
with the fl ashing, around the chimney, 1" above the top of the fl ashing
and push the storm collar down into the caulking. Insert a rain cap
onto the top of the last chimney section.
