¡ The rangetop is designed to hang from the countertop
by its flanges. Ensure that the countertop is strong
enough to support this rangetop. It may be necessary to
add a supporting cleat along each side or a 2 x 4 corner
brace.
→ "Countertop cutout", Page 11 As an alternative you
can construct a deck to set the rangetop on.
¡ The rangetop can be installed in various positions with
the front either flush or projecting, depending on the
countertop’s depth.
¡ The upper shaded area behind the appliance indicates
an opportunity to discolor the back wall under certain
cooking conditions.
¡ There must be a minimum of 5" (127 mm) side clear-
ance from the appliance to combustible vertical sur-
faces above the 36" (914 mm) counter height.
¡ Within the 5" (127 mm) side clearance to combustible
vertical surfaces above 36" (91.4 cm), the maximum
wall cabinet depth must be 13" (330 mm).
¡ Wall cabinets within this 5" (127 mm) side clearance
must be 18" (457 mm) above the 36" (914 mm) high
countertop.
¡ The maximum depth of the cabinets hanging on either
side of the hood is 13" (330 mm).
¡ There is a 36" (914 mm) minimum clearance required
between the top of the cooking surface and the bottom
of an unprotected cabinet. A 30" (762 mm) clearance
can be used when the bottom of the wood or metal cab-
inet is protected by not less than ¼" (6 mm) of a flame
retardant material covered with not less than No. 28
MSG sheet steel, 0.015" (0.38 mm) thick stainless steel,
0.024" (0.61 mm) aluminum, or 0.02" (0.51 mm) thick
copper.
¡ Establish the centerline of the appliance’s desired loca-
tion. It should be the same as the center of the over-
head ventilation hood.
¡ Cut the openings depending on the installation location.

Rear clearance requirements
To avoid staining on the back wall, high temperature, non-
porous construction materials suitable for use in a cooking
environment are recommended.
IMPORTANT: There is a possibility to discolor the back
wall under certain cooking conditions.
Models suitable for 0" rear clearance to combustible sur-
faces:
¡ PCG305xx
All other models:
¡ When using the included island trim a minimum 6"
(152 mm)* rear clearance is required to a combustible
surface*.
¡ When installing against a combustible surface, a Ther-
mador low backguard is required for a 0'' rear clearance
to the combustible surface. A Thermador low backguard
must be purchased separately.
¡ A rear clearance to a surface covered in a non-com-
bustible material (metal, ceramic tile, brick, marble, or
stone)* Δ , is 0" when using the included Island Trim.
Additional requirements
¡ If a solid side cabinet wall exists on one or both sides,
you will need to notch the front corner of the cabinet to
match the countertop notch and to allow clearance for
the rangetop front. See Detail X
→ "Countertop cutout", Page 11
¡ If a supporting deck is used, the sides or bottom of the
cutout may be solid combustible or noncombustible ma-
terial. If the bottom is solid, provide a 12'' by 12'' (305
mm x 305 mm) cutout in the left rear corner of the sup-
porting deck. This will provide clearance for the gas inlet
and power cord.
¡ Always keep appliance area clean and free from com-
bustible materials, gasoline and other flammable vapors
and liquids.
¡ DO NOT obstruct the flow of combustion and ventilation
air to the unit.
