CONVERTING TO LP GAS (Standard Twin Burner models only)
or Converting Back to Natural Gas from LP
Broil Burner (on some models)
To convert to LP gas,
use a 1/2″ wrench to
turn the upper
burner orifice spud
clockwise. Tighten
spud only until it is
snug with the base.
To prevent damage,
do not overtighten spud.
To convert to natural gas, loosen the spud
about 2 turns.
CONVERT AIR ADJUSTMENT SHUTTER
For LP gas, loosen the
Phillips head screw and
rotate the shutter to the
full open position. With
baffle in place, flames
should have approximately
1-inch blue cones and should not extend beyond
the edges of the burner baffle. After 30 seconds
of burner operation, check for flames lifting off
burner ports. If lifting is observed, gradually
reduce air shutter opening until flames are
stabilized.
For natural gas, the shutter should be open
1/2″ or about 3/4 of the way open.

CHECK FOR LEAKS
When all connections have been made, make sure
all range controls are in the off position and turn
on the main gas supply valve. Use a liquid leak
detector at all joints and connections to check for
leaks in the system.
When using test pressures greater than 1/2 psig
to pressure test the gas supply system of the
residence, disconnect the range and individual
shut-off valve from the gas supply piping. When
using test pressures of 1/2 psig or less to test the
gas supply system, simply isolate the range from
the gas supply system by closing the individual
shut-off valve.
CAUTION: DO NOT USE A FLAME TO
CHECK FOR GAS LEAKS.

CONVERTING SURFACE BURNERS
1. Lift cooktop.
2. Lift burner assemblies straight up and set
aside to gain access to surface burner spuds.
3. With a 7mm, 5/16″ or a small adjustable
wrench, remove each of the four spuds on the
surface burner
gas inlet tubes and
replace them with
the correct gas
spuds mounted in
a holder at the
right rear of the
range, above the
regulator. Natural
gas spuds are
brass and LP gas
spuds are red or
silver. (Mount the
spuds that you removed from the inlet tubes
back in the holder.) To prevent leakage, make
sure spuds are securely screwed into gas inlet
tubes.
4. Replace the burner assemblies.
5. Keep all spuds with your range so you have
them if you move or get a different gas hook-up.

CONVERT THE OVEN BURNER ORIFICES
Oven Burner
1. Remove oven door, storage drawer or broiler
drawer and oven bottom. The lower burner
orifice spud is located behind the storage drawer,
broiler drawer or kick panel. (On some models, a
metal shield must be removed to access the
orifice.)
2. To convert to LP gas,
use a 1/2″ wrench to
turn the lower burner
orifice spud clockwise.
Tighten the spud only
until it is snug. To
prevent damage, do not
overtighten the spud.
To convert to natural gas,
loosen the spud about 2 turns.
