Ducting Information

General
When planning the path for ducting to the outside, keep in mind the following guide-
lines:
- Minimize use of elbows and transitions in ductwork as to maximize air flow to out-
side of building. An efficient airflow path contributes to the overall efficiency of the
Vent Hood.
- DCS recommends the use of "smooth wall" ducting, not flexible ductwork.
- Transitions are required from rectangular to round ducting
(see transitions as shown below)
- Duct tape may be used at ducting joints.
DCS-IVH-48 Requirements
- DCS recommends the use of 10" round ducting which provides 78.6 In. 2 of sur-
face area.
- See Duct Accessories below on for ratio to 10" transition.
- Alternate duct sizes in rectangular style may be used. If a rectangular duct style is
used, the duct must equal at least 78.6 In. 2 for best results. ( E E x x a a m m p p l l e e - - 3 1/4"x 24"
duct = 78 In. 2 )
- Maintain consistent ducting square area as to avoid reduced air flow. [ie.- With a
IVH-48 Hood, connecting a 4"x13" ( 5 5 2 2 I I n n . . 2 2 ) to a 10"round ( 7 7 8 8 . . 6 6 I I n n . . 2 2 ) is not recom-
mended]
DCS-IVH-36 Requirements
- DCS recommends the use of 7" round ducting which provides 34.7 In. 2 of surface
area.
- Alternate duct sizes in rectangular style may be used. If a rectangular duct style is
used, the duct must equal at least 34.7 In. 2 for best results
Duct Accessories
- Wall Caps and Roof Caps must have free open area equal to duct size diameter.
- Note that a Sealed Back Draft Damper may reduce air delivery.
- Transition for right, left or rear air discharge also available.
