L Series Built-In Ovens
For ease of installation, Wolf recommends using 33" (838)
wide cabinets with 30" (762) ovens and 39" (991) wide
cabinets with the 36" (914) L series oven. The installation
opening must have a flat, level base platform to support
the oven. Single ovens require a minimum base support of
250 lbs (113 kg). The double oven requires a minimum
base support of 400 lbs (181 kg).
IMPORTANT NOTE: A minimum 24" (610) of usable
cabinet depth is required or the back panel of the cabinet
may need to be removed for proper installation. The electrical box must be flush with the back panel of the cabinet.
The L series oven is installed by inserting into cabinetry
from the front. The oven has a face trim on all four sides
and will overlap stiles and rails. The trim overlaps 3/16" (5)
on the top, 1/8" (3) on the bottom and 3/4" (19) on each
side.
COMBINATION INSTALLATIONS
Wolf built-in ovens are designed and agency approved for
installation with Wolf cooktops, microwaves and warming
drawers only. The nominal width of the built-in oven
should match the nominal width of the cooktop. A built-in
oven cannot be installed below a Wolf rangetop.
A single oven may be installed next to another L series
single oven. You must allow for a 2 1/2" (64) space between
the oven rough openings. Also, a separate inner wall is
required for each oven between openings.

Install the Oven
IMPORTANT NOTE: Before moving the oven, protect any
finished flooring to avoid damage to the floor.
Move the oven into position near the installation opening.
Remove and discard packing materials. Remove the box
containing oven components found in each oven cavity.
The oven is very heavy—use caution when lifting. Do
not lift the oven by the door handle. This will damage
the oven door and hinges.
To reduce the weight of the oven, it may be necessary to
remove the oven door. If so, a pin will need to be inserted
into the spring-loaded hinge assembly to prevent it from
snapping closed. For each oven door, only one hinge arm
is spring loaded, requiring use of the hinge pin. The hinge
pin can be found taped to the inside of the oven door. It
will need to be inserted through a hole in the left hinge
arm (facing the oven).
OVEN DOOR REMOVAL
1) Open the oven door. Remove both upper and lower
mounting screws of the hinge retainer plate. The oven
gasket may have to be moved slightly to access the
bottom screw.
2) Move the hinge retainer plate forward slightly. It will
remain on the hinge assembly after the mounting
screws have been removed.
3) Insert the door hinge pin through the hole in the left
hinge arm. Refer to the illustration below.
4) Carefully close the oven door to about a 60° angle from
horizontal and lift the door away from the oven. A slight
rocking motion may be required for removal.
Failure to insert the hinge pin in the hinge arm will
cause damage to the oven. Do not lift or carry the oven
door by the door handle.
IMPORTANT NOTE: Door removal should be done only
by a qualified service technician or installer. Door removal
and reinstallation may cause damage to the porcelain
oven interior.

ELECTRICAL CONNECTIONS
Verify that power is disconnected from the electrical
box before proceeding.
With the oven positioned directly in front of the installation
opening, feed the conduit through the opening in the
cabinet platform (if applicable). Depending on local codes,
connect the oven to the electrical supply following steps
for either a three-wire or four-wire electrical system.
POSITION THE OVEN
Carefully lift the oven up to the opening. Resting the oven
on the cabinet base platform, slide the oven into the
opening until it is approximately 6" (152) from full insertion.
Make sure the conduit slides through the opening in the
platform as the oven is moved into place.
IMPORTANT NOTE: The conduit must fit into the recessed
area along the right rear edge of the oven. Make sure it is
not trapped between the oven and cabinet wall.
IMPORTANT NOTE: To avoid interference, a 90° door stop
may be required for any appliance or cabinet door installed
next to an L series oven.
THREE-WIRE ELECTRICAL SYSTEM
1) Where local codes permit, connect the ground appliance wire to the neutral (white) supply wire.
2) Connect the ground and white appliance wires to the
neutral (white) supply wire in the electrical box.
3) Connect the black appliance wire to the black (L1)
power supply wire in the electrical box.
4) Connect the red appliance wire to the red (L2) power
supply wire in the electrical box.
FOUR-WIRE ELECTRICAL SYSTEM
1) Separate the ground and white appliance wires.
2) Connect the white appliance wire to the neutral (white)
supply wire in the electrical box.
3) Connect the black appliance wire to the black (L1)
power supply wire in the electrical box.
4) Connect the red appliance wire to the red (L2) power
supply wire in the electrical box.
5) Connect the ground appliance wire to the green/
ground house grounding wire in the electrical box.
Do not block the exhaust vent located at the bottom
of the oven. It must remain clear for proper ventilation.

MOUNT OVEN TO CABINETRY
OVEN DOOR REINSTALLATION
Once the oven is fully inserted into the opening, locate the
mounting holes on the oven side trim. There are four
mounting holes for a single oven and six for a double
oven. Refer to the illustration below. Use a 1/16" drill bit to
drill pilot holes into the cabinet. Using the wood screws
provided, secure the oven to the cabinet.
1) Hold the oven door on both sides and position it with
door hinges aligned with openings in the oven frame.
Failure to install the mounting screws may cause the
oven to tip forward during use.
2) Holding the oven door at an approximate 30° angle
from vertical, slide the hinges into the openings
until the bottom hinge arms drop fully into the hinge
receptacles.
3) Open the oven door to its fully opened position.
Remove the hinge pin from the appropriate hinge arm.
Refer to the illustration below.
4) Reinstall the hinge retainer plate with upper and lower
mounting screws.
5) Open and close the door completely to ensure that it is
properly installed.
IMPORTANT NOTE: Fully extend the hinge claw which is
opposite the hinge pin location and insert into the hinge
pocket prior to inserting opposite side. This will ease the
installation of the oven door.
