THE CHIMNEY
4.1
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 Security fireplace model BIS ULTRA is listed only with Security Chimneys
International Ltd 6" dia. chimney systems.
3.
A chimney venting a fireplace shall not vent any other appliance.
4.
The minimum chimney height is 12 ft. (3.7 m). In altitude, add 18" (450 mm) to the
chimney for every 2000 feet (600 m) above sea level.
5.
All chimney installations must include at least one support. The maximum chimney
length that can be supported by the fireplace is 9 ft. (2.75 m) for Secure Temp
S2100+
/
Nova Temp
, 12 ft. (3.7 m) for Secure Temp
ASHT+
/ Nova Temp
and 20
ft. (6m) for AC chimney.
6.
The chimney must extend at least 3 ft. (915 mm) above its point of contact with the
roof and at least 2 ft. (610 mm) higher than any wall, roof or building within 10 ft.
(3m) of it (Figure 24).
7.
If the chimney extends higher than 5 ft. (1500 mm) above its point of contact with the
roof, it must be secured using a roof brace.
