4ELECTRICAL CONNECTIONS
An adequate electrical supply and outlet must be used
to operate the electrical parts of your oven.
A. The oven cord has a three-prong plug and must be
used with a properly grounded three-hole outlet with
a standard 120 Volt, 60 cycle AC household current.
B. Install the electrical outlet below the oven on the left
side, in a location that is easily reached through the
FDELQHWGRRUVVHH)LJ
C. If you do not have a three-hole grounded outlet,
have a qualified electrician change your old one.
D. A grounding adaptor will be needed to convert the
old one until the outlet can be replaced. This method
is only temporary, and a qualified electrician should
test it to be sure it meets requirements.
Always unplug the oven cord before making any
electrical repairs to the oven. When unplugging the
oven, always grasp the plug, never the cord.
WARNING NEVER USE AN EXTENSION CORD
TO CONNECT THE OVEN TO THE ELECTRICAL
SUPPLY.
WARNING Do not under any circumstances
cut or remove grounding prong from oven cord.
Failure to provide proper polarization may create a
hazardous condition.
5GAS CONNECTIONS
WARNING Do not operate the burners of
this oven when using LP (bottled) gas before
converting the pressure regulator and burner
orifice for LP gas usage.
See page 2 for all gas requirements.
A. Shut off the gas supply at the shut-off valve.
B.5HPRYHWKHH[LVWLQJRYHQLIQHFHVVDU\
C. Discard any old or used connectors.
WARNING Never reuse old flexible
connectors. The use of old flexible connectors can
cause gas leaks and personal injury. Always use
new connectors when installing a gas appliance.
D. Be sure no strain has been placed on the
connecting line assembly.
To prevent any leaks, use a pipe joint compound
that resists the action of LP gas on the male outside
threads.

8CHECK THE BURNER FLAMES FOR
NATURAL GAS
The oven is factory-adjusted for use with Natural Gas
in most areas. But, since the gas in some areas may
vary, you should check all adjustments described
below. If you are to use LP Gas, see LP Adjustments
at the back of this guide.
NOTE: Bake and broil flame must be checked with the
door closed to properly check flame characteristics. To
properly check the bake burner, the oven bottom and
oven baffle must be removed.
Turn on the bake or broil burner.
As you watch the flame with the oven door
closed, check the following through the oven door
window:
1. Burner flames should not flutter or blow away
from the burner.
2. They should be blue in color with no trace of
yellow.
3. The inner cone of the flame should be

MAKE THE LP GAS CONVERSION
WARNING If you are using LP (bottled) gas,
all the adjustments described below must be made
before you make any burner adjustments or use
the oven.
WARNING This conversion must be
performed by a qualified installer or gas supplier
in accordance with the manufacturer’s instructions
and all codes and requirements of the authority
having jurisdiction. Failure to follow instructions
could result in serious injury or property damage.
The qualified agency performing this work
assumes responsibility for the conversion.

3FOR BAKE AND BROIL BURNERS
Use a 1/2” open end or adjustable wrench to turn the
orifice hood in the LP direction, about 1-1/2 turns, until
snug.
IMPORTANT: Do not overtighten or you may bend
the orifice hood or needle.
5ADJUST AIR SHUTTER
NOTE: The Bake and Broil burner flame must be
checked with the door closed to properly check flame
characteristics.
Turn on the bake or broil burner.
As you watch the flame with the oven door closed,
check the following through the oven door window:
A. Burner flames should not flutter or blow away from
the burner.
B. They should be blue in color with no trace of yellow.
C. The inner cone of the flame should be approximately
1/2” to 3/4” long.
IN SOME CASES
A. With LP gas, some yellow tipping on the outer cone
is normal.
B. Foreign particles in the gas line may cause an
orange flame at first, but this will soon disappear.
4CHECK FLAME SIZE
Check the inner cone of
the flame. It should be
approximately 1/2” to 3/4”
long for the oven and broil
burners until snug.
If the flame size is too long,
use a 1/2” open-end wrench
or adjustable joint pliers to
adjust the orifice hood, by
turning in the LP direction.
WARNING If you attempt to measure the inner
cone of the flame, please use caution; burns could
result.
