GAS CONVERSION
FOR LIQUID PROPANE:
Liquid propane requires the air mix fixture connected to
the burner.
Make sure the brass ring back is rotated back to expose
the six holes in the air mix fixture.
(See Figure L.)
FOR NATURAL GAS:
Remove the air mix fixture and replace it with an NG
orifice.
The NG orifice is required to prevent excessive gas flow.
(see Figure M.)
Attach the NG flex line to the burner with a 1/2” adapter.
If you have been using your fire pit and choose to use a different type of fuel, you can convert your fire pit to use
either liquid propane or natural gas any time you wish.
Before you begin, read the gas requirement on page page 4. Fire pit owners who convert from liquid propane need
to have a proper natural gas line installed, preferably by a licensed contractor.
Make sure the fire pit is cool and all gas lines have been shut off. Remove the decorative stone from the fire pit. Lift
the burner plate out of the fire pit and locate the air mix connector attached to the burner.
After you have finished, set the burner plate back in place and connect to a fuel source. Perform a leak check before
you use the fire pit.
