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 outside chimney,
are especially prone to flow reversal.
2. The IHP fireplace model Villa Vista™ is listed only with Security
Chimneys International ltd. 7" diameter chimney systems models
ACBI or ASHT+ or S2100+.
NOTE: Use of ACBI chimney with these fireplaces require the use of a
starter section used at the fireplace top collar. Use H3805
or H3806
(ACBI7SBA30

3. A chimney venting a fireplace shall not vent any other appliance.
4. The minimum chimney height is 12 feet (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 maxi-
mum chimney length that can be supported by the fireplace is 20 feet
(8m) for ACBI
chimney and 12 feet (3.7 m) for ASHT+
*
6. The chimney must extend at least 3 feet (915 mm) above its point of
contact with the roof and at least 2 feet (610 mm) higher than any
wall, roof or building within 10 feet (3m) of it (see Figure 21).

7. If the chimney extends higher than 5 feet (1500 mm) above its point
of contact with the roof, it must be secured using a brace and guy
wires.
8. A rain cap must be installed on top of the chimney. Failure to install
a rain cap may cause corrosion problems.
9. Portions of the chimney which may extend through accessible spaces
must be enclosed to avoid contact with combustible materials or
damage to the chimney.

NOTE: 2" clearance to combustibles around chimney components required.
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.
