MODEL NUMBER VOLTAGE CIRCUIT RATING FREQUENCY PHASE
P304 120 VAC 10 Amps 60 Hz. Single
P366 120 VAC 10 Amps 60 Hz. Single

For these gas range models, 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 modules, require 120 VAC to operate
safely and properly. An improper 120 VAC power
supply will cause malfunction, damage to 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 accom slished 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 Electrical 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.
Electric wiring diagrams and schematics have
been placed in the toe kick area of the range for
access by a qualified service technician.
IMPORTANT
Dedicated, 20 AMP service is required for model P34GE, with electric griddle.
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 1/2 psig (3.5kPa.).
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 (3.5kPa.).
When checking the manifold gas pressure, the inlet pressure to the regulator should be at leas 6.0" (14.9
mb) W.C. for natural gas or 11.0" (27.4 mb) for propane.
Do not attempt any adjustment of the pressure regulator.
