Every time. I place the chimney over the burner for 5 mins then turn it off.
Just FYI for you guys that have a gas assist later model performer that uses the small bottles. The adapter hose that allows the Qs to use the 20 pound bottles fits the performer also. If you don't move your performer around a lot it's cheaper and easier then buying new ones or refiling the small bottles. HERE
i still cant figure out why they changed to the smaller bottles.
I think because the smaller bottles are much more common then the 5lb bottles, you can find the smaller bottles almost anywhere not so much the other one.
