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 dual
fuel 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.
It is recommended that you use a Wolf Pro
wall or island ventilation hood or hood liner
with the Wolf dual fuel range. Pro Ventilation
information can be found on our website,
wolfappliance.com. Also refer to the Wolf
Design Guide for Pro ventilation recommenda-
tions.
Wolf dual fuel 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.
Wolf dual fuel ranges using natural gas
function up to an altitude of 8,000' (2438 m)
without any adjustment. Natural gas and LP gas
installations from 8,000' (2438 m) to 11,000'
(3353 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.
The 30" (762) dual fuel range requires a
240/208 V AC, 60 Hz, 30 amp fused electrical
supply to operate the electrical portions of the
range.
Wolf dual fuel ranges are designed with a
terminal block on the rear of the range. The
terminal block allows for a 3-wire or 4-wire
installation. For a 4-wire installation, the ground
strap from the unit to the terminal block must
be cut. Two concentric knockouts on the base
of the unit are provided to allow a certified elec-
trical contractor to wire the range directly to the
electrical supply. The terminal block will also
accept an appliance cord that is sized correctly
for the range’s voltage and amperage.
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.
