CONVERSION TO LP GAS 

II. Unit doesn’t have Air shuttle Bracket

1) Remove vent trim rear cover and rear cover.

Then remove the nozzle holder using 13/32” or
10mm wrench and Phillips head screwdriver.

2) Remove the orifice spud from nozzle holder

using a 13/32” or 10 mm nut driver.

3) Install the LP orifice spud(Y) to the nozzle holder.

To prevent leakage, make sure the orifice spud is
securely screwed into the nozzle holder.

3. CONVERT BROIL BURNER ORIFICES 

BROIL BURNER

1) Remove oven door and broil burner assembly.

Then remove the wire cover using a Phillips
head screwdriver.

2) Release the connector of the igniter.
3) Remove the orifice spud from nozzle holder

using a 13/32” or 10mm wrench.

4) Install the LP orifce spud(F) to the nozzle holder.

To prevent leakage, make sure the orifice spud is
securely screwed into the nozzle holder.

4. CONVERT SURFACE BURNERS

1) Remove grates, burner caps and burner heads.
2) Remove the brass orifice spud in the chimney of

each burner using a 13/32” or 10 mm nut driver.

3) Install the LP orifice spuds into their correct

positions as described previously.

4) To prevent leakage, make sure the orifice spuds

are securely screwed into the gas supply tubes.

5) For the right front burner, the choke and self

threading screw will be needed as shown in
Fig.1.Insert the choke into the burner base, then
insert the set screw into the burner base and
tighten securely. Make sure the screw head is
against the shoulder (within choke notch), so it
does not have any rotational movement.

6) Put the old orifice spuds into conversion kits

and place back on the range for possible future
conversion.

NOTE : If an orifice spud is accidentally dropped, the

cooktop can be raised as follows:

1) Remove vent trim rear cover, rear cover, vent

trim and vent cover.

2) Using a Phillips head screwdriver remove the 2

side and 2 front screws of the cooktop.
(On some models : Remove only the 2 front
screws of the cooktop)

3) Remove (11EA) hex-Phillips head screws on

the cooktop and lift it.

When reinstalling
the cooktop be
sure to align the
electrodes with
the openings in
the cooktop.
