Make sure the gas valve on the propane tank is closed first—just turn the valve clockwise to a full stop.
Getting ready to grill for the first time? Here’s how to attach your propane tank to the grill. Every grill is different, so view your manual first for instructions on how to place the tank on the grill. Once you securely attach the tank to the grill, attach the gas using the following steps.
Also make sure all the knobs on your grill are turned to off.
Inspect both the seal (for cracks) and the tank for damage. If it's damaged, return it.
Remove the seal from the propane tank. Always use the cap and strap supplied with the valve.
Hold the regulator in one hand and insert the nipple into the valve.
Do not use tools to tighten. Using your other hand tighten the coupling nut to the tank valve keeping the regulator aligned to insure the connection isn't cross threaded.
Turn the coupler clockwise to tighten all the way to a full stop.
