Proper installation/ ducting is
extremely important to ensure
maximum performance. Use a qualified
and trained installer.
DUCTING
• Check with a qualified and
trained installer or local codes
for makeup air requirements, if
any.
• Max. duct run
o For 1,200 CFM—50’ (15.2 m)
o For 1,500 CFM—75’ (22.9 m)
o Duct run length is for
general reference only; for
longer duct runs, increase
duct size and contact a
qualified and trained
installer.
o The 1,500 CFM ventilator
should be used with longer
duct runs.
o Straight runs and gradual
turns are best; for example,
each 90° elbow is equivalent
to 5 – 10 feet (1.52 – 3.05
cm) of straight run.
• 10” duct run for 900 – 1500
CFM
o Never use flexible duct; it
creates back pressure/air
turbulence and greatly
reduces performance.
