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.

• Gas range models PRG304,
PRG36 and PRG48 must be
plugged into a 3-prong
grounding type receptacle.
• Dual Fuel range models
PRDS304. PRDS36 and
PRDS48 can be cord-con-
nected or hard-wired to the
power supply, as described on
Page 17.
• Prior to servicing appliance, always
disconnect appliance electrical
supply cord, if so equipped, from

• 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
National Electric Code.
