D. Chimney Height / Rise and Run
This product was designed for and tested on a 6 inch
(152mm) chimney, 14 to 16 feet (420-480cm) high,
(includes appliance height) measured from the base of the
appliance. The further your stack height or diameter varies
from this configuration, the greater the likelihood it may
affect performance.
Chimney height may need to be increased by 2 - 3% per
each 1000 feet above sea level. It is not recommended to
use offsets or elbows at altitudes above 4000 feet above
sea level or when there are other factors that affect flue
draft.
