Choose an appropriate location to install the exterior hoods:
•
There must be a minimum distance of 6 feet (1.8 m) between the hoods to avoid cross-contamination
•
There must be a minimum distance of 18 inches (457 mm) from the ground
Refer to figure below for connecting insulated ducts to the exterior hoods. An “Anti-gust intake hood” should be installed in regions where
a lot of snow is expected to fall.
