STEP 6: ELECTRICAL REQUIREMENTS, CONNECTION & GROUNDING
absence of local codes and
ordinances, the power supply
connection shall be in accor-
dance with the National
Electric Code.
Observe all governing codes
and ordinances when ground-
ing. In the absence of these
codes or ordinances observe
National Electrical Code ANSI/
NFPA No. 70 Current Issue.
See pages 17 and 18 for
grounding method.
Electrical wiring diagrams and
schematics have been placed in
the toe kick area of the range
for access by a qualified service
technician.
The PRDS Dual Fuel Ranges
may be connected to a 120/
208 VAC power supply.

For the PRDS Dual-Fuel
Ranges, a neutral supply wire
must be provided from the
power source (breaker/fuse
panel) because critical range
components, including the
surface burner spark
reignition module, require
120 VAC to operate safely and
properly. An improper
120/240 VAC power supply
will cause malfunction,
damage this appliance, and
possibly create a condition of
shock hazard. If the correct
power supply circuit is not
provided, it is the responsibil-
ity and obligation of the
installer or user to have proper
power supply connected. This
must be accomplished in
accordance with all applicable
local codes and ordinances by
a qualified electrician. In the
• For the PRG All-Gas Ranges,
improper polarization of the
120 VAC electrical supply
circuit will cause malfunction
(such as continuous sparking
of the burner igniters), may
damage this appliance, and
could create a condition of
shock hazard at the igniter of
each burner. If the circuit is
not correctly polarized, it is
the responsibility and obliga-
tion of the installer or user to
have the existing receptacle
changed to a properly polar-
ized receptacle in accordance
with all applicable local codes
and ordinances by a qualified
electrician. In the absence of
local codes and ordinances,
the receptacle replacement
shall be
in accordance with the
Na
tional Electric Code.
