Thermador PHxxGS Installation Instruction

English 6

The supplied transition mounts to the top or rear of the 
hood depending on the discharge direction.

1.

A minimum height clearance of 6” (152mm) is needed 
above the hood for transition mounting.

2.

Align mounting holes at base of transition with the 
mounting holes of the 1/2” (13mm) flange located at 
the top or rear of the hood, depending on direction of 
discharge (see Figure 2 on page 5).

3.

Fasten transition to hood using (2) sheet metal screws 
included with hood (see Figure 3 and Figure 4). 

4.

Seal connection between transition and hood with 
aluminum tape.

5.

Remove tape holding damper closed. 

Figure 5 shows a typical installation of the hood with a duct 
cover. Accessory 6” (152mm) and/or 12” (305mm) duct 
covers are used to fill the space between the hood and 
ceiling (available for purchase separately).

The installation height ranges from a minimum height of 30” 
(762mm) to a maximum height of 40” (1016mm); however, 
it is necessary to follow the cooking appliance manufac-
turer’s installation instructions for proper hood height. In 
Figure 5 one 6" (152mm) duct cover has been used in this 
installation. Add or subtract duct covers as appropriate to 
accommodate ceiling height and recommended hood 
height. The duct cover structure is supported by the hood.

NOTICE:
The hood could incur some damage from heat if a 
Professional Series Range or Cooktop is operated with 
multiple burners at high settings under a hood that is 
installed at minimum clearances.
