How to Convert an Old Propane Tank to a New Propane Tank

Reach underneath the grill assembly and twist the propane tank valve to the "off" position, even if you think it's already been done.

Twist off the safety clamp wingnut (if such a clamp exists) that holds your tank in place on the grill. Put the wingnut in the spice tray on your grill (if it has one) so the part doesn't get lost. Do the same for the outside part of the clamp.

Firmly grab the grill twist valve and gas-line hose screwed onto your tank. Twist it loose until it is completely free of the tank valve. Push the hose aside. Grab the propane tank by the handle and the bottom with both hands and lift. Pull the tank off the grill frame and free of the assembly.

Load the tank in your vehicle and keep it well-ventilated. Don't put it in the trunk of the car and forget about it. Drive to your local propane dealer or hardware store that stocks propane tanks. Swap out your old tank for the new tanks being offered. Pay the extra fee, if necessary.

Pay for a filling of the new tank with propane. Carry the tank back to your vehicle and lift it in with both hands, bending at the knees if you need to lift it from the ground. Don't bend with your back.

Place the new tank onto your grill assembly when you get home. Place the safety clamp onto the tank hook and screw the wingnut into place again. Twist the grill gas-line twist valve onto the new tank until it is firmly seated on the tank valve. Open your grill lid. Turn on the gas flow and press the ignition clicker. Use an extended lighter tool if you don't have an ignition clicker on your grill. Open up the other lines when the grill is lit. Wait for all the gas lines to light up to confirm the system is working.
