GENERAL NOTES
ü
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 startup characteristics. Exterior
chimneys are also prone to down drafting and flow reversal. Installations which are located low in the
house such as in a basement, in combination with outside chimneys, are especially prone to flow
reversal.
ü
A chimney venting a fireplace shall not vent any other appliance.
ü
The
MAGNUM ZC
fireplace is not listed for use with a masonry chimney or with chimney liner.
ü
The minimum chimney height, including fireplace, is 12’ 6” (3.8 m) for vertical chimney.
ü
Chimney – Any listed type HT 7” or 8” diameter 2100 degree insulated or air-cooled.
ü
The maximum chimney height supported by the fireplace is 10’ (3 m). If additional height is required,
use a roof support at 30’ (9 m) interval.
ü
The chimney must extend at least 3’ (915 mm) above its point of contact with the roof and at least 2’
(610 mm) higher than any wall, roof or building within 10’ (3000 mm) of it (SEE FIGURE 18).
ü
If the chimney extends higher than 5’ (1500 mm) above the roof, it must be secured using a roof brace
or guide wires.
ü
A rain cap must be installed on top of the chimney. Failure to install a rain cap may cause the fireplace
to corrode.
The warranty will be void if a rain cap is not used.
ü
Cut and frame square holes in all floors and the roof to provide 2” (50 mm) of clearance between the
chimney and any combustible material. Do not fill this 2” (50 mm) space with any material.
ü
Portions of the chimney may extend through accessible spaces and shall be enclosed in all cases to
avoid personal contact with the chimney and damage to the chimney.
