54 Solution 2.5-ZC Fireplace Installation and Operation Manual
There are two reasons why the
chimney in the house at right will cold
backdraft when it is cold outside and
there is no fire burning in the fireplace.
First, the chimney runs up the outside
of the house, so the air in it is colder
and denser than the warm air in the
house. And second, the chimney is
shorter than the heated space of the
house, meaning the negative pressure
low in the house will pull outside air
down the chimney, through the
fireplace and into the room. Even the
finest fireplace will not work well when
connected to this chimney.
8.5 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 SOLUTION 2.5-ZC is listed only with chimney systems described in TABLE 2 -
LISTED CHIMNEYS FOR YOUR SOLUTION 2.5-ZC.
3. A chimney venting a fireplace shall not vent any other appliance.
4. The minimum chimney system height for a straight installation 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 and 12 ft. (3.7 m) for 1" Solid Pack Chimney.
6. The chimney must extend at least 3 ft. (92 cm) above its point of contact with the roof
and at least 2 ft. (61 cm) higher than any wall, roof or building within 10 ft. (3.1 m) of it.
See the figures on point 11 bellow to determine the configuration that applies to your
roof (flat or sloped roof and the distance between the chimney and the highest point of
the roof and/or the nearest chimney).
7. Deviations should be avoided whenever possible, especially the most pronounced.
Each deviation adds some restriction to the chimney system and may lead to draft
problems.
