CHIMNEY INSTALLATION
GENERAL NOTES
1.
The Security Fireplace Model SECURE HE43-1 is listed only with Security Chimneys International Ltd.
chimney systems.
Do not connect the fireplace to a masonry chimney, chimney liner, or other brand
of factory-built chimney.
2.
The Oliver Macleod chimney models and are respectively equivalent to Security
Chimneys International Ltd. chimney models ASHT+ and S2100+.
3.
In areas with continuous temperatures below 0º F (-18º C), 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
located in a basement, in combination with outside chimneys, are especially prone to flow reversal. In
cold areas, air cooled chimneys should not be used in an exterior installation.
4.
A chimney venting a fireplace shall not vent any other appliance.
5.
The minimum system heights are indicated in Table 1.
6.
In altitude, add 18" (450 mm) to the chimney for every 2000 feet (600 m) above sea level
.

Chimney Model
ASHT+ / / S-2100+ / / AC

Two Offsets (4 elbows) 20 ft (6.10 m)
Table 1
NOTE: A maximum of 2 offsets is allowed.
NOTE: In areas where winter temperatures are normally below freezing, the air cooled chimney may
produce condensation. This condensation may corrode the top of the fireplaces and is not covered under
warranty. For optimum performance of your fireplace, Security Chimneys International recommends the use
of an ASHT+ / or S2100+ / chimneys.
7. All chimney installations must include at least one support. The maximum length of chimney that can be
supported by the fireplace is 12 ft. (3.6 m) for S2100+/, 18 ft (5.4 m) for ASHT+/ and
26 ft. (8 m) for AC chimney.
8. 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. (3 m) of it (see Figure 12).
9. 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 or guide wires.
10. A rain cap must be installed on top of the chimney. Failure to install a rain cap may cause the fireplace
to corrode and operate inefficiently.
11. Cut and frame square holes in all floors and the roof to provide a 2" (50 mm) clearance between the
chimney and any combustible materials. Do not fill this 2" (50 mm) space with any material (see Fig 13).
12. Portions of the chimney which may extend through accessible spaces must be enclosed to avoid contact
with combustible materials or damage the chimney.
