I bought this a Couple of Weeks Ago and Only Used it Once. You MUST Turn On the Gas for at Least 2 Minutes on these New WEBER'S For the Pressure to Balance Out OR they Don't Heat Up to the Highest Temperature, and the One I have ONLY Reached 450 Degrees, SO I'M GOING TO SEE HOW HIGH IT GOES THE NEXT FEW TIMES THAT I USE IT BECAUSE IT SHOULD GO TO AT LEAST 500 DEGREES.
