What are Venturi Tubes

Venturi tubes mix gas and air in the tubes before sending the mixture on to the burners where the mixture is ignited and used to produce flame. The tubes are named for the Venturi Effect, which states that as liquid moves through a narrow tube to a wider tube, it accelerates and decreases in pressure at the narrow end and decelerates and increases in pressure at the wider end. The practical effect of the venturi burner system is that the tubes control the fuel for the grill and are therefore integral in controlling the temperature of the grill.

Why You Should Replace Your Venturi Tubes

The environment surrounding your grill can have a great effect on the venturi burner system. Often insects and dirt are attracted to the tubes, and both can clog the small openings that allow air to flow into the tube. If the tubes get too clogged, they can become a safety hazard. Tubes have exploded in the past because of clogs and the changes in pressure in the tubes. You don't want to have clogged tubes for cooking reasons as well. Clogged tubes can distort the level of heat that you think you are sending to the grill, changing the level that the grill's burners actually receive. With new tubes, you will be able to properly control the temperature, turning up the heat when you need it and cooling it down when you want to slow cook your food.
