10. Use (2) 5/8” (16mm) screws to secure the wood 
bracket leaving 1/4” (6mm) of each screw exposed for 
hanging the hood. 
Note: 
Dashed line indicates cutout needed for clearance of the 
transition (Figure 9).
Discharge Direction: Horizontal discharge requires a wall 
cutout, as shown in Figure 9, to provide clearance for the 
transition. The location of the cutout is determined by the 
hood installation height.The transition supplied with the 
hood connects to standard 10” (254mm) round duct. 
Figure 11 shows the hood configured for vertical discharge. 
Installations using this method require a cutout in the 
ceiling to accommodate 10" (254mm) duct and the 1/2” 
(13mm) conduit carrying power to the unit. 
Duct covers, sold separately, are available to cover the 
space between the top of the hood and ceiling (see 
Figure 13).
