You should always perform a leak test when the propane tank is replaced, moved or when replacing the hose and regulator.
LP Cylinder Leak Test
For your safety
- Leak test must be repeated each time LP cylinder is exchanged or refilled.
- Do not smoke during leak test.
- Grill must be leak tested outdoors in a well-ventilated area, away from ignition sources such as gas fired or electrical appliances. During leak test, keep grill away from open flames or sparks.
- Use a clean paintbrush and a 50/50 mild soap and water solution. Brush soapy solution onto areas indicated by arrows in figure below.

Leak Testing Valves, Hoses and Regulator
- Turn all control knobs to the OFF position.
- Be sure regulator is tightly connected to the LP cylinder.
- Completely open LP cylinder valve by turning hand wheel counterclockwise. If you hear a rushing sound, turn gas off immediately. There is a major leak at the connection. Correct before proceeding.
- Brush soapy solution onto area circled below, or other similar fittings on your grill.
- If “growing” bubbles appear there is a leak. Close LP cylinder valve immediately and retighten connections. If leaks cannot be stopped do not try to repair. Call for replacement parts.
- Always close LP cylinder valve after performing leak test by turning hand wheel clockwise.
