An LP (liquid propane) regulator adjusts the pressure from a gas tank through a hose connected to an appliance such as a heater or outdoor grill for cooking. The regulator controls gas flow through the line to maintain a safe pressure. Without a regulator, propane flames could rage out of control. If you need to adjust the LP regulator when using it with a new appliance, the pressure screw is typically located underneath a plastic or metal cap on the side.
Close the valve knob on the LP tank, typically mounted on a brass stem at the top.
Remove the plastic or metal cap covering the regulator adjustment screw on the side of the regulator.
Turn the screw below the cap clockwise to raise the pressure flow through the regulator, using a screwdriver. Turn the screw counterclockwise to lower the pressure of the gas the regulator will allow through the system.
Replace the cap on the regulator before opening the LP tank valve.
