Thermador PH30HS Installation Instruction

English 8

Optional duct covers shown in Figure 10 may be used to fill 
the space between the hood and ceiling in wall mount 
installations. 6" and 12" high duct covers are available and 
may be ordered separately.

1. If multiple duct covers are used, connect the pieces 

together using sheet metal screws provided with the 
duct cover accessories.

2. Attach the duct cover(s) to the hood using sheet metal 

screws as shown in Figure 10.

3. From inside of hood, insert screws supplied (#8 x 5/8") 

through holes labeled “L,” one (1) on each side and 
four (4) along the front, into bottom of the cover. 

The hood can be installed under a cabinet by supporting 
the hood from the top.

Note:
The cabinet must be structurally joined to the wall studs to 
support the weight of this hood.

Figure 11 shows the four (4) screw holes labeled “K” used 
for mounting the hood to the bottom of the cabinet.

Make sure both knockouts have been removed.

1. In the base of the cabinet, drill 1/8" tap holes (See 

Dimension A in Figure 11 and in Table). Screw in 
four (4) #10 x 1" screws (provided with hood) leaving 
1/4" exposed.

2. If the hood is installed for vertical discharge, use 

Figure 12 to create clearance holes for passage of the 
transition and conduit (See Dimension B in Figure 12 
and in the Table.)
