Hey What’s-a-Matta-U!
MY grill doesn’t get as hot as it did the last time I used it!

Tip – each time you turn off the propane, do so at the burner and not at the tank.
Once the burners are turned off it’s OK to turn off the fuel at the propane tank.
Why?
With the new regulators if you turn off the flow at the tank to shut your grill down, and leave on the burner controls, the next time you turn on the tank valve, even if you’ve turned off the burner controls, you might trigger the anti-flow mechanism.
The propane flow will be restricted and you may experience low heat output.
This is true for all propane fueled outdoor cookers and stoves for all manufacturers.

After turning off the propane tank shouldn’t you turn on/off the burner control to clear the propane left in the line.
It’s not a big issue – and OK to do or not. The most important thing to remember is to have the burners in the OFF position when you turn ON the propane at the tank or, if you use natural gas, at the valve.
