Hey Bob,
A warning. I was having trouble lighting my grill last night (it would light but the flame wasn't normal, very low, as if gas wasn't getting to the burners). The tank happened to be fairly low on propane, so today I got a brand new one. Went to light it and same result. I know something else was going on. Looked under the hood and found a quarter sized hole in the propane hose where it had been melted just under the burner. You might want to check yours out. I think mine was looped the wrong way which put it too close to the burner area. I'm going to ask Weber for a free replacement since in my mind that's a pretty major design flaw.
