This torch has a burst feature. The burst sequences are random. During bursts, the flame height is around 3', while the standard flame height is around 20", assuming a proper installation.

These tiki torches are fabulous and can be seen on our projects. These come as pictures, without a decorative exterior. They are meant for custom built applications. We often connect them to wifi switches for convenience. When turned on, the torches will automatically open the valve and light once the proper pilot temperature is reached.
