Hood Exhaust Duct

Outside ventilation requires hood exhaust duct. Use only metal duct. Read the following carefully.

Exhaust Connection: Hood exhaust has been designed to mate with standard 3 1/4 inch x 10 inch rectangular duct. If round duct is required, rectangular-to-round transition adaptor must be used. Do not use less than 6 inch diameter duct.

Rear Exhaust: If rear or horizontal exhaust is to be used, care should be taken to align exhaust with space between studs.

Maximum Duct Length: Total duct length of 3 1/4 inch x 10 inch rectangular or 6 inch diameter round duct should not exceed 140 equivalent feet for satisfactory air movement.

Elbows, Transitions, Wall and Roof Caps, Etc.

Elbows, transitions, wall and roof caps, etc., create additional resistance to airflow and are equivalent to a section of straight duct. When calculating total duct length, add equivalent lengths of all transitions and adaptors, plus length of all straight duct sections. Chart below shows approximate feet of equivalent length of some typical ducts.

	Duct	Equivalent Length
	Rectangular-to-Round Transition	5 FT.
	Adaptor	5 FT.
	Adaptor
	Wall Cap	40 FT
	90° Elbow	10 FT.
	45° Elbow	5 FT.
	90° Elbow	25 FT.
	45° Elbow	5 FT.
	Roof Cap	24 FT.
