Installation procedure

Disassembling the rangetop

9 CAUTION

Before proceeding with the conversion, shut off the

gas supply to the appliance prior to disconnecting the

electrical power.

Disconnect the appliance from electrical power by

unplugging the electrical cord from its receptacle or

by disconnecting power at the circuit breaker box.

To disassemble the rangetop

1. Remove the rangetop grates and the burner caps.

2. To facilitate the removal of the spill tray, remove the T-

20 torx screws in the front face of the island trim or

backguard.

3. Use a 16 mm hex head bit or Allen wrench for burners

labeled ‘D’ or ‘F’. Use a 9 mm hex head bit or Allen

wrench for burners labeled ‘B’ to remove the burner

venturi from each burner base.

TIP: If a 16 mm hex head bit is not readily available, a 5/8''

hex bit can be selected. Alternatively, a bolt with 5/8''

head either “double-nutted” or tightened into the chuck

of a power driver can be used.

4. Disconnect the igniter. Carefully pull up on the burner

base.

5. Remove the screw securing the burner pedestal with a

T-30 torx driver. Carefully remove each burner

pedestal.

6. Remove the spill trays by pivoting the trays up and out

the back.

7. Remove the heat shield on some models. Some

models have a double-width shield that extends under

adjacent spill tray.

Converting the regulator to LP

The gas regulator is located in the rangetop, left side of

appliance. Exact location will vary per model.

2. Grasp the plastic button stem firmly and pull it

forcefully from the metal cap. The stem snaps snugly

into an indent in the cap and may require a strong pull

to remove. (Hint: it may be helpful to gently “rock”

the plastic stem while pulling it from the metal cap.)

3. Rotate the stem 180° so the letters “LP” on the stem

are upside down when the cap is set flat on its head.

Snap the stem back in place in this position inserting it

into the indent in the metal cap.The stem should snap

into place.

4. Reinstall conversion cap, configured for LP gas, back

into top of the regulator.

Changing the STAR

®

burner

orifices

Changing “D” and “F” STAR burners only

To prepare the 7 mm, 9/32'' socket, or ¼'' nut driver for

STAR burner orifice conversion

NOTE: This procedure facilitates the changing of the

orifices in the “D” and “F” STAR burners only. For the

smaller sized “B” burners in 305 models, this procedure

will not work because the socket is too big for insertion

through the orifice holders. To change “B” size STAR

burners, refer to page 11.

1. Trim a small piece of the foam tape provided with this

kit to about 1/4 – 1/2'' (6 – 12 mm).

2. Place foam tape over the edge of a 7 mm or a 9/32''

socket, or with 1/4'' nut driver used to replace the

burner orifices, as shown below.

• The foam tape helps to retain the orifice in the

end of the nut driver so it will not fall inside the

appliance during orifice removal or installation.

To replace the STAR “D” and “F” burner orifices

1. With the foam tape wrapped nut driver, reach down

through the jet holders and remove the gas orifice

from the STAR burner’s jet holder.

1. Remove the

conversion cap with

a 7/8'' socket or

wrench, or an

adjustable wrench.

2. Label each of the removed orifices, noting from which

burner they were removed, in the event the appliance

is converted back to natural gas in the future.

For your convenience, note the orifice sizes and

locations in the following table.

3. Locate the proper STAR

®

burner

orifices included with the kit.

Orifices are stamped with the

orifice diameter size on the side.

4. Replace orifices as indicated in the tables beginning

on page 12. Ensure the orifice is completely seated

and tight to the jet holder to avoid possible gas leaks.

NOTE: All of the replacement orifices in the conversion kit

have straight threads (not pipe threads) and do not

require thread sealing compound.

Changing “B” STAR burners (305 models

only) and/or “D” and “F” STAR burners

This procedure can be applied when:

• Converting size “B” burners.

• Preferred by the installer to change orifices of any size

burner (“B”, “D”, or “F”).

• A 7 mm or 9/32'' socket, or ¼'' nut driver is not

available for use when changing the orifices on “D”

and “F” burners.

To replace the “B” STAR burner orifices (or any burner

size orifice)

1. From the side of the jet holder, insert a 9/32'' open

end wrench into the space between the metal wire

and the jet holder. Remove the gas orifice from the

STAR burner’s jet holder.

2. Label each of the removed orifices, noting from which

burner they were removed, in the event the appliance

is converted back to natural gas in the future. (See

table to the left.)

3. Locate the proper STAR burner

orifices included with the kit.

Orifices are stamped with the

orifice diameter size on the side.

4. Replace orifices as indicated in the tables beginning

on page 12. Ensure the orifice is completely seated

and tight to the jet holder to avoid possible gas leaks.

NOTE: All the replacement orifices in the conversion kit

have straight threads (not pipe threads) and do not

require thread sealing compound.

IMPORTANT: DO NOT bend the broil burner orifice

bracket. Ensure that the broiler orifice is aligned to the

center of the burner tube inlet.

2. Label each of the removed orifices, noting from which

burner they were removed, in the event the appliance

is converted back to natural gas in the future.

For your convenience, note the orifice sizes and

locations in the following table.

3. Locate the proper burner orifices included with the kit.

Orifices are stamped with the orifice diameter size on

the side.

4. Replace orifices as indicated in the table. To avoid any

possible gas leak in this area, ensure the orifice is

completely seated and tight to the burner orifice

holding bracket and the 90° orifice elbow.

NOTE: The replacement broil orifices have straight

threads (not tapered threads) and DO NOT require thread

sealing compound.

leaks.

9 CAUTION

DO NOT spray water solution onto exposed electrical

components. If solution does drip onto electrical

components, shut the power off before wiping off the

electronics.

9 CAUTION

Ensure that the STAR burner igniter wire terminals do

not touch the chassis metal, or any metal part, to

prevent sparking. Do not touch the igniter wires while

the burner is turned on to avoid being shocked.

Leak testing should occur after the orifices are replaced

and before the appliance is fully reassembled. However,

the doors of the appliance must also be installed and

closed in order to leak check the broil and bake burners.

Leak testing of the appliance shall be conducted

according to the following instructions.

9 WARNING

When cooking with the STAR burners, the burner

flame size should be adjusted so it does not extend

beyond the edge of the cooking utensil. This

instruction is based on safety considerations.

To observe the burner flames, it may be necessary to turn

off lights or close window blinds to darken the room for

easier viewing of the flame.

Reassemble the rangetop as follows:

TIP: Use the burner venturi as a centering guide when

remounting the burner pedestals. If the pedestals are

centered, the venturi will slide in and out easily after the T-

30 torx head screw has been secured. If the pedestals are

not centered properly, loosen the mounting screw and

recenter the burner until the venturi slides freely.
