3. THE CHIMNEY
3.1 CHIMNEY INSTALLATION NOTES
1. If possible, install an interior chimney as it will provide better performance. In areas
with continuous temperatures below -18 ° C (0 ° F), the use of an exterior chimney
increases the likelihood of operating problems such as low draft, high rate of
creosoting, and poor start-up characteristics. Exterior chimneys are also prone to
down-drafting and flow reversal. Installations, which are located on lower floors
in the house, such as in a basement, in combination with outside chimney, are
especially prone to flow reversal.
2. The WFP-75 is listed only with chimney systems described in table 2.
3. The chimney must be dedicated and must not vent any other appliance.
4. The minimum chimney system height is 15 ft. (4.6 m).
5. All chimney installations must include at least one support. Reducing the amount of
chimney weight on the fireplace will help avoid the noise created when the fireplace
expands. This can be achieved by having the chimney supported by the supports.
The maximum chimney length that should be supported by the fireplace is 9 ft. (2.75
m) for 2" Solid Pack Chimney, 12ft. (3.7m) for 1" Solid Pack Chimney, and 26ft. (8m)
for AC Triple Wall Chimney.
6. The chimney must extend at least 3 ft. (1 m) above its point of contact with the roof
and at least 2ft. (0.6m) higher than any wall, roof or building within 10ft. (3m) of it
(Figure 42).
7. If the chimney extends higher than 5
ft. (1.5 m) above its point of contact
with the roof, it must be secured
using a roof brace.
8. A rain cap must be installed on top of
the chimney. Failure to install a rain
cap may cause corrosion problems.
9. Cut and frame square holes in all
floors, ceilings, and roof that the
chimney will go through to provide
a 2" (50mm) clearance between
the chimney and any combustible
materials. Do not fill this 2” space with
insulation or any other combustible
material.
10. Portions of the chimney which may
extend through accessible spaces
must be enclosed to avoid contact
with combustible materials or damage
the chimney.
