⚠ 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.

⚠ 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.

Gas leak checking the rangetop STAR® burners

1. Make sure that the orifices have been tightened and that all valves and controls are in the OFF position.
2. Turn on electric and gas supplies.
3. Spray a generous amount of soap and water mixture—or other solution designed for checking gas leaks—on the threaded junction at the base of the orifice, the elbow fitting, and gas tube compression nut. (A 25% dishwashing liquid to water mixture is effective for this.) Avoid spraying electrical components.
4. Turn the corresponding STAR burner knob to HI while firmly blocking the STAR burner’s orifice hole with a soft rubber pencil eraser, your finger, or something similar.
5. Monitor the base of the orifice junction, elbow fitting, and compression nut to see if bubbles are forming anywhere around the connections.
   • Bubbles forming are indications of gas leaks.
6. If appliance leaks, repair all gas leaks immediately. Do not over-torque the junctions, orifices or nuts, or bend the gas tubes. Repeat for all STAR burners.

Gas leak checking the broil orifice(s)

1. Spray a generous amount of soap and water mixture—or other solution designed for checking gas leaks—on the threaded junction at the base of the orifice, the elbow fitting, and gas tube compression nut. (A 25% dishwashing liquid to water mixture is effective for this.) Avoid spraying electrical components.
2. Turn the mode knob and the oven temperature knob to BROIL while blocking the broil orifice hole with a soft pencil eraser, your finger, or something similar.
   • There will be a delay of approximately 45 to 90 seconds as the safety valve coil heats to release the valve’s actuator. A single pop noise can usually be heard as the broiler’s safety valve opens.
3. Monitor the base of the orifice junction, elbow fitting, and compression nut to see if bubbles are forming anywhere around the connections.
   • Bubbles forming are indications of gas leaks.
4. If appliance leaks, repair all gas leaks immediately. Do not over-torque the junctions, orifices or nuts, or bend the gas tubes.
5. If applicable, repeat for the auxiliary broil orifice.

Gas leak checking the bake orifice(s)

1. Spray a generous amount of soap and water mixture—or other solution designed for checking gas leaks—on the threaded junction at the base of the orifice, the elbow fitting, and gas tube compression nut. (A 25% dishwashing liquid to water mixture is effective for this.) Avoid spraying electrical components.
2. Turn the mode knob to BAKE and the oven temperature knob to any setting while blocking the bake orifice hole with your finger.
   • There will be a delay of approximately 45 to 90 seconds as the safety valve coil heats to release the valve’s actuator. A single pop noise can usually be heard as the broiler’s safety valve opens.
3. Monitor the base of the orifice junction, elbow fitting, and compression nut to see if bubbles are forming anywhere around the connections.
   • Bubbles forming are indications of gas leaks.

5. If applicable, repeat for the auxiliary bake orifice.
6. If the appliance has been satisfactorily leak checked, turn off the gas and electric supplies. Reinstall the auxiliary bake burner mounting bracket, if applicable, and continue to “Checking the flame and burner performance” .

Checking the flame and burner performance

Checking the STAR® burner performance

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 star-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.

Checking the STAR® burner ignition and flame

1. Push in the burner control knob and turn it to HI.

   • The igniter electrode and spark module will produce a clicking sound. Once the air has been purged from the supply lines, the burner should light within four seconds.
   • The flames should be stable, with no excessive noise. The inner cones of the individual flames should be defined and separate from each other. Portions of the flame, along the burner, should not exhibit excessive or continuous indications of “lifting” or “lazy flame”.
     NOTE: It is normal for slight yellow tipping of the flames to appear after a few minutes of operation using Propane (LP) gas. Orange-colored streaks in the flame are produced from burning airborne debris; this is normal during initial start up and should dissipate within a few minutes of operation.
     Yellow flames:
     Further adjustment is required. Yellow tips on outer cones:
     Normal for LP gas Soft blue flames:
     Normal for natural gas

2. Adjust the burner’s control valve to LO to see that the flame continues to wrap around the burner. Blow out the flame, or use a quick fan motion from a writing tablet or piece of cardboard to extinguish the flame. Observe the burner’s ability to reignite and wrap around (also called “carry-over”) the burner within several seconds. This flame “carry-over” is essential for proper burner ignition and re-ignition.

3. Test re-ignition of the XLO® and observe the carry-over of the small simmer flames as the XLO system cycles the burners on and off.

   • If the low flame performance is not acceptable, it may be necessary to readjust the valve screw for a STAR burner that does not have sufficient carry-over of the low flame. Turn the valve screw slightly counter-clockwise until carry-over of the flame is acceptable.
   • If the burner flame is uneven, flutters, makes excessive noise, or lifts, some of the slots in the burner base may be blocked with food spillage or other debris.
   • Clogged slots can be cleared using a straightened paper clip, needle, or similar object. Encrusted food or debris can sometimes be removed using a steel wool pad or fine wire brush.
   • Burner flames that are “lazy”, with excessively-long flames, can be created by an incorrectly fitted burner cap—from which many of the outer mantles of the individual flames will tend to “coalesce” or blend together. Verify that the burner cap is seated properly on its burner base. The cap should fit reasonably flat when correctly-positioned on the base and not rock significantly.

4. Repeat the ignition and flame test procedures for each rangetop STAR burner.

Setting the STAR® burner valve screws
A flat-head screwdriver with a 2.5 mm wide tip (included) is used to adjust the valve screws.

To set the burner valve screws

1. Turn the knob counterclockwise.

   • Standard burners: Turn a full turn until knob cannot be turned anymore.
   • XLO burners: Turn to LOW.

2. Remove the knob from the valve stem by slowly pulling knob straight out, away from the control panel.

3. To set the burner valve screws on all models except 8-burner models:
   Remove the bezel-mounting screw located to the right of the valve stem using a T-20 star-head screwdriver. Insert the included flat-blade screwdriver into the hole of the bezel mounting screw. To set the burner valve screws on 8-burner models:
   Insert the included flat-blade screwdriver into the hole of the valve stem. The removal of the bezel screw is not required.

4. Access to the valve screws through the clearance hole in the spark module. You should feel the engagement of the screwdriver and the valve screw.

5. Adjust the valve screw by turning the valve screw about an 1/8th turn. Turn the screw clockwise to reduce simmer flame size. Turn the screw counter-clockwise to make the simmer flame larger. Adjust the valve screw as little as required to reach satisfactory simmer results. Adjustments should be done after the range has been fully converted. Due to normal fluctuations in gas pressure, over-adjustment of valve screw may affect flame stability.

Checking the gas broil ignition and flame (gas range only)
NOTE: The oven door(s) must be installed and closed.

1. Turn on the main oven mode knob and the oven temperature knob to BROIL.
2. The hot-surface igniter will attempt to light the broiler after approximately 45 to 90 seconds, as the safety valve coil heats to open. Once the air has been purged from the gas supply line, the broiler should light within four (4) seconds.
3. Observe the broil flame performance through the oven door window. The ceramic tiles of the burner should glow red hot (infrared) after several minutes of operation. If after several minutes with the burner lit, the broiler only has a small amount of red glow (and burns mostly with blue flame floating on the burner surface), check that the broiler orifice is aligned to the center of the burner tube inlet.
4. Repeat for the auxiliary oven, if applicable.
5. If the broil burner burns satisfactorily, reassemble the backguard onto the appliance.

Checking the gas bake ignition and flame (gas range only)
NOTE: The oven door(s) must be installed and closed.

1. Install the front panel (see page 12 ).
2. Turn the main oven mode knob to BAKE and the oven temperature knob to any setting.
   • The hot-surface igniter will attempt to light the burner tube after approximately 45 to 90 seconds, as the safety valve coil heats to open. Once the air has been purged from the gas supply line, the burner should light within four (4) seconds.
   • Observe the bake burner flame through the slots in the bottom front panel. Look for considerable “yellow tipping,” noting that some small amount of yellow tipping is normal in the flame characteristics of burners running with propane (LP) gas, flame lifting, or lazy flames.
3. Repeat for the auxiliary oven, if applicable.
4. If the bake burner burners perform satisfactorily, reinstall the kick panel .
