STEP 6: ELECTRICAL REQUIREMENTS, CONNECTION & GROUNDING
• Prior to servicing appliance,
always disconnect appliance
electrical supply cord, if so
equipped, from wall receptacle. If
appliance is hard-wired to power
supply, disconnect power to unit
by turning off the proper circuit

• For the PRSG 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.

• For the PRSE 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 re-ignition module, require
120 VAC to operate safely and
properly. An improper 120/240
VAC power supply will cause
malfunction, damage this appli-
ance, and possibly create a
condition of shock hazard. If the
correct power supply circuit is not
provided, it is the responsibility
and obligation of the installer or
user to have the proper power
supply installed and connected.
This must be accomplished in
accordance with all applicable
local codes and ordinances by a
qualified electrician. In the
absence of local codes and

for access by a qualified service
technician.
• The PRSE Dual Fuel Ranges
may be connected to a 120/
