If more than one elbow is used, make sure that there is a minimum of 24" (61 cm) of straight vent between any two elbows. Do Not install two elbows together. It is recommended that you use round vent instead of rectangular vent, especially if elbows are required. If rectangular vent is required, it should be transitioned to 6" (15.2 cm) round vent as soon as possible. Determining the length of system you need: centerline of cooktop cutout To calculate the length of system you need, add the equivalent feet for each vent piece that will be needed. See example for 6" (15.2 cm) round vent system. Vent system cutout dimensions for internal blower models only. Exterior mounted blower systems connect with 10" (25.4 cm) round vent. The cutout locations for this vent system will depend upon your specific installation.
