Install Downdraft System
Determine Equivalent Length of Vent System
This range is equipped with a dual range blower. It is shipped
from the factory for Low Range installations. If vent system
equivalent length exceeds 30 ft (9.1 m), the downdraft blower
motor must be converted to High Range for best performance.
See “Calculating Vent System Length.”
To Convert:
Gently remove the spring loaded Restricter Ring from the blower
inlet by pressing on one of the 3 springs.
Determine which venting method to use: floor, rear wall, or left
side venting. Go to the section for your type of venting.
Rear Wall Venting
1. Mark the wall at the center of the cabinet opening.
2. Check for obstructions before marking the vent hole location.
Mark a horizontal line 8³⁄₁₆" (20.8 cm) from the floor. Mark a
vertical line up to a maximum of 2¼" (7.9 cm) from the right
side of the cabinet centerline.
3. Draw and cut a 6¼" (15.8 cm) diameter hole.
4. Position blower motor in cabinet opening. Connect vent
system to blower motor outlet using a vent clamp.
5. Mount blower motor to the floor with 4 - #8 x ¾" hex head
screws provided.
