LP CONVERSION INSTRUCTIONS
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 ALL
instructions could result in serious injury or property
damage. The qualified agency performing this work
assumes responsibility for the conversion.
The pressure regulator and the burner orifices are set for natural
gas. To use Liquid Propane Gas,the regulator and burner orifices
must be converted.
The LPorifices for the cooktop burners are shipped in a box on the
back of the range.
WARNING
Do not operate the cooktop or oven burners of this range
when using LP (bottled) gas before converting the pressure
regulator and burner orifices from LPgas use. Failure to do so
could cause high flames and toxic fumes which can result in
serious injury.
To adjust your range for use with LPgas, follow these instructions:
1. Disconnect all electrical power, at the main circuit breaker or
fuse box.
2. Shut off the gas supply to the range by closing the manual shut-
off valve.
A.The pressure regulator is located on the rear of the range.
(Somemodels will have a metal shield protecting the regulator
that must be removed for conversion and reinstalled when
conversion is complete.) The pressure regulator is located in the
lower, right hand side of the range as viewed from the rear.

NOTICE:
If you are using LP(bottled) gas, all adjustments described
in the following steps must be made before you make any
burner adjustments.
B. Unscrew the plastic-protected hex-nut cap.
C. Completely remove the protective plastic cap off the threaded
metal cap.
D. Turn the metal cap so the type of gas being converted to is
displayed and replace the protective plastic cover.
E. Screw the hex-nut cap back into the regulator.

C. Remove the LPorifice spuds, from the box provided. The LP
orifice spuds have the letter "L" on the top.
To aid in identifying the proper location for the LPorifices
during a conversion from Natural Gas to LPGas, paint color
codes have been added to the side or top of the orifice. See
the chart below. Each orifice may also show a series of
engraved marks (I, II,III ...)located on the top.

D. Install the LPorifices in their precise locations.
Toprevent leakage, make sure the orifice spuds are securely
screwed into the gas supply tubes.
E. For the extra large burner (left front-on some models), the
choke and set screw will be needed. Insert the choke into the
burner head, then inset the set screw into the burner head
and tighten securely. Make sure the screw head isagainst
the shoulder (within the choke notch) so it does not have any
rotational movement.

WARNING
The following adjustments must be made before turning on the gas
to the burner. Failureto do so could result in seriousinjury due to
high flames and toxic fumes.
BAKE BURNER ORIFICE ON DOUBLE OVEN
1.Remove oven door, oven bottom, and burner. On some models,
a metal shield must be removed. Some models will have a cover
over the burner that will need to be removed.

AIR SHUTTER SETTINGS FORBAKE AND BROIL BURNERS
1. Use a screwdriver to loosen the air
shutter screw.
2. Adjust the air shutters for LPgas by
rotating the shutter to the fully open Screw
position. Your final settings may vary. Air shutter
3. Retighten the air shutter screw.
Bake and broil flame must be checked
with the door closed to properly check flume characteristics.
4. Turn on the gas.
5. Turn on the electricity.
6. Reinstall the oven door.
7. Turn on the bake or broil burner.
8. Asyou watch the flame with the oven door closed, check the
following through the oven door window.
a. If the flames are yellow, open the air
shutter more.
b. If the flames blow away or flutter from the burner, close the
air shutter more.
,_ WARNING
If you attempt to measure the inner cone of the flame, please use
caution: burnscould result.
9. Checking the flame size:
It should be approximately 1/2"
to 3/4" long for the bake and broil
burners.
The combustion quality of the
burner flames needs to be
determined visually.
INNER CONE

NOTE:If burner flumes look like {A},further air shutter
adjustment is required. Normal burner flames should look
like (B)or {C),depending on the type of gas you use. With LP
gas, some yellow tipping on the outer cones is normal.
(A) Yellow flames:
Further Adjustment
Required
(B) Yellow tips on
outer cones:
Normel for LP Gas
(C) Soft blue flames:
Normal for Natural Gas
10.When all adjustments are made and the results are
satisfactory:
a. Replace the orifice fitting cover.
b. Replace the oven baffle (flame spreader).
c. Replace the oven bottom.
IN SOME CASES:
A. With LPgas, 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.
SPECIAL NOTE:
To convert the oven beck to natural gas, reverse the
instructions given in making LP adjustments.
Low setting adjustments must be made with two other burners
in operation on a medium setting. This procedure prevents the
low flame from being set too low, resulting in the flame being
extinguished when other burners are turned on.
A.Turn on all surface burners.
B.Turn the knob on the burner being adjusted to "LO"(LOW)or
"SIM"(SIMMER).
C.Remove the knob and insert a small, flat blade screwdriver into
the valve shaft as shown and turn clockwise to fully tighten
down the bypass screw. Repeat for each screw. For the tri-
ring burner, remove the knob and insert a small flat blade
screwdriver into the small hole to the right of the valve shaft
and turn down the bypass screw.
D.If flame appears too low or unstable, adjust valve bypass screw
slowly (turn counterclockwise-CCW) until a stable flame exists
for each burner. Remember two other burners must be turned
on to medium.
Center adjustment screw for all
burners except tri-ring. und
E.Additionally, for each burner being adjusted, quickly open
and close the oven door followed by the storage drawer while
observing flame. If flame is extinguished, continue adjusting
bypass screw CCW for larger flame. Repeat door and drawer
openings until flame is stable.
F. Replace the knob.
NOTICE:
Once the conversion is complete and confirmed, fill
out the LP sticker and include your name, organization
and date conversion was made. Apply the sticker to
the range near the regulator to alert others in the
future that this appliance has been converted to LR If
converting back to natural gas from LP,please remove
the sticker so others know the appliance is set to use
naturals gas.
