Fire-on-water is an amazing melding of two of nature's most volatile elements, and this fire feature can transform any pool, pond, or fountain into pure magic!

This 30" H-shaped burner installs under the water and attaches to an electronic ignition system. As its dual linear burners unleash gas bubbles from its jets the pilot ignition turns on and ignites the fuel on top of the water, creating a dazzling glow on top of the liquid. 

It's made of hefty stainless steel that has been sealed and coated to withstand saltwater as well as freshwater.

PLEASE NOTE: This product needs to be connected to an ignition system like the SUBmersible Electronic Ignition System (SUBEIS) or the Automated Fire On Water (AFOW) ignition system (sold separately).

Benefits and Features:

  • Creates a unique fire-on-water effect
  • 30" size is perfect for rectangular bowls and medium-sized water features
  • Made from 316 stainless steel
  • Rated for both freshwater and saltwater use
  • Features a water check valve to prevent water from entering the gas line
  • Designed for use with liquid propane fuel
  • New circular design features a lower required PSI


  • The closer you install the manifold to the surface of the water, the better the performance you will get.
  • For propane installation you may need a high output regulator, usually supplied by your gas provider. It has to be rated for at least 3 PSI and up.
  • All manifolds will be shipped with a check valve.
  • How much gas pressure do I need. You will need a minimum of 0.5 PSI for an 8" submersible manifold. For bigger manifolds you will need to increase the supply line to achieve the same effect.
  • Usual thickness of gas supply line for 8" to 18” manifolds can run off of a 1/4” supply line. For larger manifolds the gas line should not be bigger than 1-1/4".
  • A Fire Fountain or fire feature may be lit manually with a control valve close to the feature. Note: Always stand UPWIND when lighting any fire feature.
  • It is the buyer's responsibility to check local codes, restrictions and enforcement for installations. Units must be installed by a local licensed contractor.
  • Can NOT be used indoors.
  • Do not run manifold without being submersed in water!

Larger sizes or different shapes are available on custom order base. Please contact our office at 1-888-986-1535 if you'd like a larger size.

These products require a minimum 0.5 PSI of pressure to operate, assuming 1/2" to 2" of water coverage. If it is installed deeper you will need to increase the pressure.

How does it work?

When the gas is turned on, the ring will release jets of gas.

Once the electronic ignition system is turned on (SUBEIS shown), the gas will flow through the manifold, out of the water, and into the air.

After a few moments, the electronic ignition will turn on, igniting the gas.

After a few moments, the pilot light will turn on, igniting the gas that is escaping over the water.

Once the flames are lit, they will stay lit as long as the gas continues to feed through burner.

The result is that the flame will hover over the water, stopping at the waterline, keeping the manifold and electronics protected from the heat.

There is a one year warranty on the stainless steel material. The replacement tips have a 3 month warranty and can be ordered at any time. With proper maintenance, the tips should last for up to 2 years, depending on the hardness of the water. The system is very durable and is built to last.

Usually ships in 5-10 Business Days.

Due to the custom nature of this product, it is not returnable.

Fire pit has small flame
When I put my fire pit glass on top of the orafice, it seems like the glass is covering the hole/ports and the fire is very sporadic which is limiting the heat from the pit. Any suggestions on what I can do?
