THE CHIMNEY SYSTEM
Chimney Installation Notes
1. If possible, install an interior chimney as it will provide better perfor-
mance. In areas with continuous temperatures below 0°F (-18°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 which are located on lower floors in
the house, such as in a basement, in combination with an outside
chimney, are especially prone to flow reversal.

only) or ACBI.
3. A chimney venting a fireplace shall not vent any other appliance.
4. The minimum chimney height is 12 feet (3.7 m) excluding the fire-
place.
5. All chimney installations must include at least one support in order to
be able to take any lateral load. The maximum chimney length that
can be supported by the fireplace is nine (9) feet (2.75 m) for Secure
Temp S2100+ / Nova Temp HT6000+ / Secure Temp GX and 26 feet
(8m) for ACBI chimney. In altitude, add 18" (450 mm) to the chimney
for every 2,000 feet (600 m) above sea level.
6. The chimney must extend at least three (3) feet (915 mm) above its
point of contact with the roof and at least two (2) feet (610 mm) higher
than any wall, roof or building within ten (10) feet (3 m) of it (Figure
20).
7. If the chimney extends higher than five (5) feet (1,500 mm) 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" (51mm) clearance between
the chimney and any combustible materials. At the point of penetra-
tion through the floors, ceilings or roof, a 1" (25mm) clearance is
acceptable for AC chimney only (see Table 2). Do not fill the required
clearance spaces 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 to the chimney.
11.When offsets are used, the pipe may not penetrate a ceiling or floor
unless it is running vertical (no 30° offsets).

Note: 2" clearance to combustibles around chimney components re-
quired.
Note: Blown or fill type insulation materials must not be in contact with the
fireplace or in the enclosure frame as described in ''Enclosure'' section.
Note: Local codes may not require firestopping at the ceiling levels for
outside chase installations. However, it is recommended for safety and
the reduction of heat loss.
CHIMNEY INSTALLATION INSTRUCTIONS
1. Cut and frame the holes in the ceiling, floor and roof where the chimney
will pass (see Figure 21). Use a plumb-bob to line up the center of
the holes. The sizes are indicated in Table 2 for the floor and ceiling
holes and Table 3 (Page 16) for the roof holes.
