Checking for gas leaks

9 WARNING
DO NOT use a flame of any kind to check for gas
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.

Gas leak checking the rangetop STAR
burners
To leak check the rangetop's 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.
7. Repeat for all STAR burners.
