Duct Planning
WARNINGS
1. To reduce the risk of fire and
to properly exhaust air, ducted
fans must be vented to outside.
Do not vent exhaust air into
spaces within walls, ceilings,
attics, crawl spaces or garages.
2. Improper installation,
adjustment, alteration, service,
or maintenance can cause
personal injury or property
damage.
3. To reduce the risk of fire,
use only ductwork materials
deemed acceptable by state,
municipal and local codes.
NOTES:
1. Best performance is achieved
by using round duct instead of
rectangular, especially when
elbows are required.
2. If multiple elbows are needed,
ensure that there is a minimum
of 24” of straight duct between
any two elbows.
3. Avoid “S” or “back to back”
configurations caused by
adjacent elbows.

duct, should be used in areas
of extreme cold.
5. A back-draft damper at the duct
outlet may also be required.
6. Do not use flexible metal duct.
7. Do not use ductwork that is
smaller in cross-sectional area
than the recommended size
duct.
8. Do not rely on duct tape alone
to seal duct joints. Use sheet
metal screws as require to
support the duct weight.
9. The raised vent and
cooking appliance(s) must
be removable if service is
required.
10. Be certain that the ductwork
does not interfere with floor
joists or wall studs.
11. It is important to keep a
minimum number of turns in
the duct run, and to keep the
run as short as possible.
12. Do not restrict the air flow
by reducing the duct crosssectional areas when making
hard joints or squeezing
through a tight area.
13. With concrete slab
construction, "box-in" the
ductwork to prevent it from
collapsing when the wet
concrete is poured. Also allow
room for electrical conduit.
14. Cross-drafts or air currents
caused by adjacent open
windows or doors, HVAC
outlets, ceiling fans, and
recessed ceiling lights reduce
vent efficiency.

Sample problem:
Given a remote system installation having 20
feet of 3 ¼” x 10” rectangular duct, one (1)
90-degree 3 ¼” x 10” elbow, and one (1) 3 ¼”
x 10” to 8” or 10” round transition, would this
installation be proper?
Solution:
1. Add the total length of straight duct:
20’ (of 3 ¼” x 10”) = 20’.
2. Using Table above, determine the
equivalent straight length of all duct
fittings: 90-degree 3 ¼” x 10” elbow
= 15’. 3 ¼” x 10” to 8” or 10” round
transition = 4’.
3. Add (1) and (2) to determine the
total equivalent straight length of the
complete duct system: 20’ + 15’ + 4’
= 39’ total equivalent straight duct
length.
4. For the remote system with 3 ¼” x
10” duct, the maximum allowable total
equivalent straight length of duct is 40
feet. Thus, this proposed installation is
proper.
After determining that your proposed ductwork
meets the maximum duct length requirement,
proceed with the location planning.
Higher volumes of air exhausted by the vent
system result in better overall removal of smoke
and fumes from the kitchen. Longer duct runs
and greater numbers of duct transitions reduce
air volume, therefore it is extremely important
to keep duct runs as short and straight as
possible.
To ensure that your installation meets this
requirement, add the actual straight length of
duct to the equivalent straight length of all duct
fittings to determine the total equivalent straight
length of duct. (Refer to the table above, which
shows various common duct fittings with their
equivalent straight lengths for various common
duct sizes). If this total equivalent straight
length is less than or equal to the maximum
limits specified, then the installation is proper.
Consider the duct size that corresponds to the
majority of the duct used in the installation.
