3.3 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 ME150 is listed only with chimney systems described in table 1.
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. (4,5 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 12 ft. (3.7 m) for 1" Solid Pack Chimney.
6. The chimney must extend at least 3 ft. (91 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. (3.0 m) of it. See figures 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).
