CONNECTION Liquid Propane Gas Grills

WARNING: An LP (propane) tank is overfilled if it contains more than 80% by weight of its total capacity of propane (LP). An incorrectly filled or an overfilled LP (propane) tank can be dangerous. If this information is not followed exactly, a fire causing death or serious injury may occur. If a tank is overfilled and the weather causes the warming of the LP tank, (a hot day, tank left in sun or stored indoors) internal pressure is created due to expansion of the propane which in turn causes the LP gas to be released through the pressure relief valve on the tank.The pressure relief valve is a safety device required on 20 lb. propane tanks by the Department of Transportation to prevent a catastrophic tank failure due to excessive pressure. LP gas released from the tank is flammable and can be explosive.

Gas Leak Checks

Remove Control Panel for Leak Testing

1.Remove control knobs.

2.Remove the two (2) screws and washers holding each valve to the control panel and control knob bezel.

3.Loosen the control panel by removing two (2) screws from each side of the front control panel.

4.Pull control panel away from grill.

Never use a match or flame for leak detection. Use soapy water or testing solution. Brush the solution onto connection points and look closely for bubbles indicating escaping gas. If leaks are detected, shut off the main gas supply valve and securely retighten connections, then repeat the leak test.

On cabinet models, perform this operation before placing the tank into its storage compartment. After placing the tank in the compartment, recheck the tank to see if any connections were disturbed.

WARNING: Never use an open flame when testing for gas leaks. Use of an open flame may result in serious bodily injury or death, or in a fire or an explosion causing damage to property.
