Free-standing (open all around)
Measure the width "A" and the depth "B" of the
hood. Multiply "A" and "B" and add 50% (multiply the
area by 1.5).
If the free-standing fireplace is round, measure the
diameter, D, and calculate the area by using this
formula:
Area = D x D x .7854
and add 50% (multiply the area by 1.5).
The second step is to determine the size of the flue
opening. If the flue is rectangular, refer to Appendix C
on how to convert a rectangular flue to a round flue.
The third step is to make sure there are no more
than two 90° bends, and the chimney height is min. 10
feet and does not exceed 30 feet. If you exceed these
limits, you may need to use a stronger fan.
The fourth step is to cross reference the opening
and the flue size in order to determine which size fan to
use.
Stoves and fireplace inserts
Determine the are of the door opening by multiply-
ing "A" and "B". The chart on page 12 shows the size

fan to use.
Wood-fired Pizza Ovens
Determine the area of the door opening by multiply-
ing the measures "A" and "B"and the flue size (all
measures in
inches). Cross reference this information
for selection of the appropriate chimney fan. The fan
selection is based on max. 1/10"W.C. negative room
pressure.
If the application experiences more than the al-
lowed negative pressure, even if it is only temporary,
select one size larger chimney fan.
