The main purpose of a key valve is to enable flame-height adjustment and the ability to easily turn off the gas. The flex line simply connects the key valve to the burner.
Do you need a key valve/flex line?
Important: When you order a burner package and select YES for flex line/key valve, or you order a complete system from us, we will include the proper sizes and fittings required to connect the key valve to the burner. It will be the best set up for the system that you ordered.

All of the flex lines we provide are whistle free. In order for a large volume of fuel to continue through the key valve on to the burner without any loud whistling, a special line is required. Some standard, yellow flex lines will whistle very loudly when you turn up the fire.
Keep in mind, there’s a difference between whistling and the sound of mild, rushing wind. No matter what, you’ll probably have the sound of air moving through lines. That’s normal. Sometimes if there is moisture in the line, it can cause a mild whistle or gurgling sound. Over time, it should evaporate. Meanwhile, keep the burner covered when it rains.
We recommend that you schedule a professional to connect the components. With that in mind, here are some installation tips:
