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 breaker or disconnecting the
proper fuse.
Dual Fuel range models PD 304, PD36 and PD48
can be connected or hard-wired to the power supply
as described on Page 15.
Chart C: E_eotriea_ Supply Circuit Requirements
MODEL NUMB_=RVOLTAGE CIRCUIT RATmNG FREQUENCY PHA8 _=
PD304 120/240VAC 35 Amps 60 Hz_ Single
PD36 120/240 VAC 35 Amps 60 Hz. Single
PD48 120/240 VAC 50 Amps 60 Hz. Single
For the PD Dual Fuel Ranges, a neutral supply
wire must be provided from the power source
(breaker/fuse panel) because critical range com-
ponents, 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 responsibility and obliga-
tion of the installer and 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 ab-
sence of local codes and ordinances, the power
supply connection shall be in accordance with
the National Electric Code.
Observe all governing codes and ordinances
when grounding. In the absence of these codes
or ordinances observe National Electrical Code
ANSIiNFPA No. 70 current issue. See Pages 15
and 16 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 PD Dual Fuel Ranges may be connected to
a 120/208 VAC power supply.

CAUTION
The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve
during any pressure testing of the gas supply piping system at test pressures equal to or less than I/2 psig
(3.5 kPa.).
The appliance and its individual shut off valve must be disconnected from the gas supply piping system
during any pressure testing of the system at test pressures in excess of 1/2 psig (3.5 kPa.).
When checking the manifold gas pressure, the inlet pressure to the regulator should be at least 6" W.C.
(14.9 mb) for natural gas or 11" W.C. (27.4 mb) for propane.
Do not attempt any adjustment of the pressure regulator.
