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.
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.

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. Please follow
the minimum clearances established in the
finished rough opening dimensions as shown in
the Installation illustration.
IMPORTANT NOTE: A minimum 5" (127) riser is
required when installing a 30" (762) gas range
against a combustible surface.
It is recommended that you use a Wolf Pro
wall or island ventilation hood or hood liner
with the Wolf gas range. Pro Ventilation infor-
mation can be found on our website, wolfappli-
ance.com. Also refer to the Wolf Design Guide
for Pro ventilation recommendations.
The Wolf gas range requires a 110 /120 V
AC, 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 and gas supply within the
shaded area shown in the Installation illustra-
tion.
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 (propane) 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.
The Wolf gas range functions 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 Locator section of our website,
wolfappliance.com.
You must follow all National Electrical Code
and gas regulations. In addition, be aware of
local codes and ordinances when installing your
services.
Refer to the installation instructions
shipped with each Wolf product for detailed
specifications.
