Duct Information

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 the Vent Hood.

-DCS recommends the use of smooth wall ducting, not flexible ductwork.

-Transitions are required from rectangular to round ducting

	10"
	11"
	10-1/2"
18-5/8"	4-5/8"
	4-5/8"

Vertical Duct Transition

DCS-IB12 BLOWER Requires one of the following 4-1/2” x 18” to 10” round transitions (purchase separately)

Model 19052-01-Vertical discharge Model 19052-02-Rear discharge Model 19052-03-Left discharge

- Duct tape may be used at ducting joints.

DCS VH 48 / DCS VH12 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 a VH-48 Hood, connecting a 4”x13” (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.
