GENERAL:
When planning the path for ducting to the outside, keep in
mind the following guidelines:
Minimize use of elbows and transitions in ductwork
as to
maximize air flow to outside of building. An efficient airflow
path contributes
to the overall efficiency of theVent Hood.
DCS recommends the use of smooth wall ducting, not
flexible ductwork.
Transitions are required from rectangular to round ducting

/ DCS-VH
12-36 REQUIREMENTS:
DCS recommends the use of 10" round ducting which provides 78.6 sq. In. 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 78.6 sq. In. for best results. (Example- 3-1/4" x 24" duct = 78 sq. In.)
Maintain consistent ducting square area as to avoid reduced air flow.
[ie.-With
aVH-48
Hood,
connecting a 4"xl3"
(52 sq. In.) to a 10" round (78.6 sq. In.) is not recommended]
DCS-VH-36/30
REQUIREMENTS:
DCS recommends the use of 7" round ducting which provides 34.7 sq. In. 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 sq. In. 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.
