INLET PRESSURE
The Inlet pressure to the regulator should be as follows
for both operation and checking regulator setting:
NATURAL GAS:
Minimum pressure 5 inches W.C.
Maximum pressure 14 Inches W.C.
LP GAS:
MInImum pressure 11 Inches WC.
Maximum pressure 14 Inches W.C.
LINE PRESSURE TESTING
a. Testing ABOVE
3/4
Pound Per Square Inch
(Gauge1
The appliance and its indlvldual shutoff valve must be
dlsconnected from the gas supply piping system dur-
Ing any pressure testing of that system at test pres-
sures In excess of % psig.
b. Testing AT
l/2
Pound Per Square Inch (Gauge)
OR LOWER
The appliance must be Isolated from the gas supply
plplng system by closing its indlvldual manual shutoff
valve during pressure testing of the gas supply piping
system at test pressure equal to or less than l/z pslg.
To convert from NATURAL to LP gas.
a. Change pressure regulator setting from NATURAL
to LP [See To Convert Pressure Regulator.)
b. Screw the burner orlflces hoods down tight against
the orifice pins. DO NOT OVER TORQUE.
c. Remove the oven control knob and the porcelain panel
and turn the select-a-gas screw to the LP posItIon.
This screw Is locatedon theovencontrolfthermostatl.
The mid posItIon turns the oven pilot off.
d. Adjust the burner air shutter to the widest opening
that
will
not cause the flame to lift or blow off of the
burner
To convert the pressure regulator. Note: The type of gas
for which the regulator IS set
IS
stamped on the aluminum
plug on the top of the regulator (either NAT or LPI.
To change the regulator setting:
Remove the aluminum hex nut [plug] with a wrench or
coin. Turn the hex nut or plug over and screw It back Into
the regulator. Caution: Do not over tighten.
If the unit IS to be used on a NATURAL gas, NAT should
be vlslble on the regulator plug. If the unit is to be used
on LP gas, LP should be visible on the regulator plug.
OBSERVE ALL GOVERNING CODES
AND ORDINANCES
ELECTRICAL REQUIREMENTS
A 1 15 Volt, 60 Hz. AC only, 15 Ampere fused electrical sup-
ply is required [time delay fuse or circuit breaker is recom-
mended]. It is recommended that a separate circuit serving
only this appliance be provided. DO NOT use an extension
cord.
RECOMMENDED GROUNDING
METHOD
Electrical ground is required on this appliance.
DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR
REMOVE THE POWER SUPPLY CORD GROUND
PRONG.
For your personal safety, this appliance must be grounded.
This appliance
IS
equipped with a power supply cord having
a 3-prong grounding plug. To minimize possible shock hazard,
the cord must be plugged into a mating 3prong grounding
type wall receptacle, grounded In accordance with the Na-
tlonal ElectrIcal Code, ANSI/NFPA NO. 70-1961
l
* and
local codes and ordinances. If a mating receptacle is not
available, it
IS
the personal responsiblllty and obllgatlon of
the customer to have a properly grounded 3-prong wall re-
ceptacle installed by a quaIlfled electrician. See Figure I.
