The Wolf 30" (762) gas range is
available in natural or LP gas, with a top
configuration which includes four surface
burners. The model number followed by
(-LP) denotes an LP gas model.
If it looks as if it could be in a restaurant kitchen, well,
that’s natural. That’s precisely where Wolf has spent the
past seven decades, perfecting the form, function and
sheer durability of our stainless steel gas ranges.
Wolf gas ranges offer a variety of standard features such
as an infrared oven broiler, convection baking, dual brass
surface burners and our signature large red control
knobs.
Let Wolf, the corporate companion and kitchen soul
mate of Sub-Zero, fuel your passion for cooking and
kitchen design.

INSTALLATION NOTES
Refer to the illustrations and specifications
for overall dimensions, finished rough opening
dimensions and installation specifics.
IMPORTANT NOTE: Caution must be used in
planning the proper installation of the Wolf gas
range to avoid any fires or damage to adjacent
cabinetry or kitchen equipment. Be sure to
follow minimum clearances established in the
finished rough opening dimensions as shown in
the illustration on page 4.
IMPORTANT NOTE: A minimum 5" (127) riser is
required when installing a 30" (762) gas range
against a combustible surface.
A Wolf Pro ventilation hood or hood liner is
recommended. When installing a ventilation
hood, refer to the specific requirements of the
hood for the minimum dimension to countertop.
Also refer to the ventilation recommendation
charts in the Pro ventilation section of our
website, wolfappliance.com.
The Wolf gas range requires a 110/120 V AC,
50/60 Hz electrical supply to operate the
electronic ignition system. The 6' (1.8 m) power
supply cord provided with the range is
equipped with a 3-prong, grounded plug for
protection against shock hazard. The service
should have its own 15 amp circuit breaker.
Locate electrical within the shaded area shown
in the illustration on page 4.
IMPORTANT NOTE: A ground fault circuit
interrupter (GFCI) is not recommended and may
cause interruption of operation.
Wolf gas ranges are designed to operate on
natural gas at 5" (12.5 mb) WC (water column)
pressure or LP gas at 10" (25 mb) WC pressure.
The minimum line pressure for natural gas is 7"
(17.5 mb) WC and 11" (27.4 mb) WC for LP
gas. The maximum gas supply pressure to the
regulator should never exceed 14" (34.9 mb)
WC; .5 psi (3.5 kPa).
Wolf recommends the use of a 1/2" (13) I.D.
commercial type flex hose; this is the minimum
size that may be used. All plumbing to the flex
hose must be 3/4" (19) minimum I.D. pipe.
IMPORTANT NOTE: A separate external gas
shut-off valve must be located near the range in
an accessible location.
You must follow all National Electrical Code
and gas regulations. In addition, be aware of
local codes and ordinances when installing
your services.
Wolf gas ranges function up to 6,000'
(1828 m) in altitude without any adjustment.
Installations above 6,000' (1828 m) need the
high altitude kit. Contact your Wolf dealer for
details. To obtain local dealer information, visit
the Showroom Locator section of our website,
wolfappliance.com.
Refer to the installation instructions
shipped with each Wolf product for detailed
specifications.
