MASONRY CHIMNEY
Figure 12A
For optimal performance, masonry chimneys used
to vent this appliance should be lined with a 6" stain-
less steel liner. Installations into a clay flue without
a stainless steel liner may reduce efficiency, can
cause the glass to darken, and produce excessive
creosote.

Ensure that a masonry chimney meets the minimum
standards of the National Fire Protection Associa-
tion (NFPA) Standard 211. It must have at least a
5/8" (16mm) fire clay liner or a listed chimney liner
system. See Figure 12A. Make sure there are no
cracks, loose mortar or other signs of deteriora-
tion and blockage. It is best to have the chimney
inspected by a professional and be sure to have
the chimney cleaned before the stove is installed
and operated.

The flue should be checked to determine that it is
not too large for the stove. NFPA 211 allows the
cross-sectional area of the flue to be no more than
3 times the cross-sectional area of the flue collar of
the stove (28 x 3 = 84 square inches). It is recom-
mended that a chimney with a larger diameter be
relined, since the oversized flue can cause poor
performance and contribute to the accumulation
of creosote. (See page 11 for more information
about troubleshooting draft problems).

CAUTION!
DO NOT CONNECT THIS UNIT TO A CHIMNEY
FLUE SERVING ANOTHER APPLIANCE.
When connecting the stove through a combustible
wall to a masonry chimney, special methods are
needed. There are several ways to make this con-
nection, including the construction of a masonry
thimble. This installation shall conform to CAN/CSA-
B365. Check with your local building authorities
or consult the National Fire Protection Association
(NFPA 211). Refer to Figure 13B (page 13) and
Figures 14A & 14B (page 14).

THIS APPLIANCE IS MADE WITH A 6 INCH (152mm) DIAMETER CHIMNEY CONNECTOR AS THE FLUE COLLAR ON
THE UNIT. CHANGING THE DIAMETER OF THE CHIMNEY CAN AFFECT DRAFT AND CAUSE POOR PERFORMANCE.
IT IS NOT RECOMMENDED TO USE OFFSETS OR ELBOWS AT ALTITUDES ABOVE 4000 FEET ABOVE SEA LEVEL
OR WHEN THERE ARE OTHER FACTORS THAT AFFECT FLUE DRAFT. SEE PAGE 11.
