INSTALLATION INFORMATION
NEVER USE OPEN FLAMES TO CHECK FOR GAS
LEAKS. ONLY USE A COMMERCIAL LEAK DETEC-
TION SOLUTION OR SOAP SUDS AROUND GAS
CONNECTIONS TO CHECK FOR LEAKS. DO NOT
USE LIQUID NEAR VALVE STEMS.
Gas Supply
Installation must conform with local codes or, in the
absence of local codes, with the National Fuel Gas
Code.
Locate the gas supply within the shaded area shown in
the illustration for your specific model on the following
pages. The range is equipped for use with natural or liq-
uid propane (LP) gas. It is design certified by the
Canadian Standards Association (CSA) for natural or
LP gases. The product rating plate has information on
the type of gas that should be used. If this information
does not agree with the type of gas available, check
with the local gas supplier.
The range must be connected to a regulated gas sup-
ply. The supply line must be equipped with an
approved external gas shut-off valve located near the
range in an accessible location. Do not block access to
the shut-off valve. (See Figure 2.1)
A gas supply line of 3/4" (19) rigid pipe must be provid-
ed to the range. If local codes permit, a certified, 3' (.9
m) long, 1/2" (13) or 3/4" (19) ID flexible metal appli-
ance connector is recommended to connect the range
to the gas supply line. For LP gas, piping or tubing size
can be 1/2" (13) minimum. LP gas suppliers usually
determine the size and materials used on the system.
The pipe coming out the back of the range has 1/2"
(13) male threads. Pipe joint compounds, suitable for
use with natural or LP gas should be used.
Wolf LP gas ranges will function up to an altitude of
10,250' (3124 m) without adjustment; natural gas
ranges will function up to an altitude of 8,600' (2621 m)
without adjustment. If the installation exceeds this ele-
vation, contact an authorized Wolf dealer for a high alti-
tude conversion kit.
Leak Testing
Use a brush and liquid detergent to test all gas connec-
tions for leaks. Bubbles around connections will indi-
cate a leak. If a leak appears, shut off the gas valve
and adjust connections. Then check connections
again. Clean all the detergent solution from the range.
This section of the manual covers some of the installation issues that a service technician may need to know when
servicing a gas range. If additional installation information is needed after reviewing this section of the manual,
please refer to the installation guide or contact the Wolf Appliance Customer Service Department.

FAILURE TO FOLLOW INSTRUCTIONS CAN
RESULT IN SHOCK, FIRE OR DEATH.
A domestic gas range requires a 110-120 V AC, 60 Hz
electrical supply with a 15 amp circuit breaker to oper-
ate the electrical ignition system. A ground circuit inter-
rupter (GFCI) is not recommended and may cause
interruption of operation.
The power supply cord provided with the appliance is
equipped with a 3-prong (grounding) plug. The installa-
tion site must be equipped with a properly grounded 3-
prong receptacle. If the electric receptacle or the power
cord are not properly grounded and polarized, this
could cause a shock hazard and the appliance may
experience ignition problems (See Figure 3-2).
NOTE: Do not ground to a gas pipe.

Preparation
Before moving the range, protect any finished flooring
and secure oven door(s) closed to prevent damage.
To lighten the load or to fit through a door way, the oven
door(s) can be removed. Only remove if necessary. Do
not remove griddle or any other component. Door
removal should only be done by a certified installer or
service technician.
For removal, a hinge pin will be inserted into the appro-
priate hinge shown in Figures 2-3 and 2-4 below. The
pin(s) are located inside the oven door. For single oven
ranges, the hinge pin must be inserted in the right
hinge. For double oven ranges, the pins must be placed
in the outer two hinges.
Failure to insert the hinge pin in the appropriate
hinge arm will cause damage to the range.

Oven Door removal (See Figure 2-5)
1. Insert the hinge pin into the appropriate hinge.
2. Remove the lower kickplate assembly to access the
lower hinge retainer mounting screws.
3. Open the oven door and remove both upper and
lower hinge retainer mounting screws. The oven
gasket may have to be moved slightly to access the
bottom screws.
4. Move the hinge retainer plate forward slightly. The
hinge retainer plate will remain on the door hinge
after the mounting screws have been removed.
5. Carefully close the oven door to approximately 60°,
then lift the door up and out. A slight rocking
motion may be required for removal.

Placement
Do not lift or carry the oven door by the door handle.
The range has rear casters which allow for easy move-
ment by lifting the front of the unit.
Use an appliance dolly to move the unit near the open-
ing. Remove and recycle packing materials. Do not dis-
card the anti-tip bracket supplied with the range.
If a riser has been specified, refer to the installation
instructions packaged with the riser. The riser must be
installed before the range is installed.
Anti-Tip Bracket
To ensure the anti-tip bolt engages the bracket, position
the bracket 3" (76) from the left side of the opening.
Refer to Figure 2-6.

Drywall Application
After properly positioning the anti-tip bracket, mark
holes, then use a Philips screwdriver or a low rpm
power drill to drive the wall anchor into the surface of
the wallboard until flush. Pre-drill holes if needed. For
hard wallboard or double-board construction, use a 1/4”
drill bit. For solid plaster, use a 7/16” drill bit. Refer to
Figure 2-7. Use #8 screws and flat washers to fasten
the bracket to the wall.

After properly positioning the anti-tip bracket, drill 3/16”
(5) pilot holes through the floor. Use #12 screws and
flat washers to secure the bracket to the floor.
Concrete Floor Application
After properly positioning the anti-tip bracket, drill 3/8”
(10) holes into the concrete a minimum of 1-1/2’ (38)
deep. Use 3/8” wedge anchors to secure the bracket to
the floor.

• A CHILD OR ADULT CAN TIP THIS APPLIANCE
AND BE KILLED.
• VERIFY THE ANTI-TIP DEVICE HAS BEEN
PROPERLY INSTALLED AND ENGAGED.
ENSURE THE ANTI-TIP DEVICE IS RE-
ENGAGED WHEN THIS APPLIANCE IS MOVED.
REFER TO THE ILLUSTRATIONS ON THIS AND
THE PREVIOUS PAGE FOR HOW TO VERIFY
CORRECT INSTALLATION.
• TO REDUCE THE RISK OF BURNS, DO NOT
MOVE THIS APPLIANCE WHILE HOT.
• DO NOT OPERATE THIS APPLIANCE WITHOUT
THE ANTI-TIP DEVICE IN PLACE AND
ENGAGED. FAILURE TO DO SO CAN RESULT IN
DEATH OR SERIOUS BURNS TO CHILDREN OR
ADULTS.
Leveling the Range
Raise the unit to the desired height by adjusting the
front legs and rear casters. The front legs can be
adjusted by rotating the hexagonal leg clockwise to
raise and counterclockwise to lower. The rear casters
(wheel assemblies) can be adjusted by rotating them
clockwise to raise and counterclockwise to lower. For
fine adjustments of the rear wheel assembly, a long
sturdy screwdriver or bar can be used when the appli-
ance is in place by inserting the tool between the wheel
brackets and spinning the rear wheel assembly with the
tool as needed.
NOTE: If necessary, perform pre-leveling of the range
before pushing it into its installation, with fine adjust-
ments made after the appliance is installed.
Anti-Tip Bolt Adjustment
Once the anti-tip bracket is secure and the appliance is
installed and leveled, adjust the anti-tip bolt so the top
of the washer is 7/8” (22) maximum from the floor.
Slide the range into the opening and verify the anti-tip
bolt is engaged. Refer to Figures 2-8 and 2-9.
