Acceptable Media for Fire Features
List of Acceptable Media for Fire Features
Lava Rock (or other Igneous Rock) NO LARGER THAN 2” in diameter
Fireglass approved for use in fire features
Manmade stone for use in fire features (Refractory Material)
Installation Note
The use of media inside fire features is recommended due to the fact it enhances the look of the fire
feature but also improves its performance by forcing the gas emanating from the burner to mix as it
passes through the media. This ‘mixing’ of gases creates an even flame throughout the feature and
helps spread the flame from the Pilot Burner throughout the burner quicker than when there is no
media. Recommended thickness of the media above the burner element is NO MORE than 2”.
Due to the fact the Pilot Burner must be partially exposed to oxygen in order to ignite the pilot flame
during startup DO NOT COMPLETELY COVER THE PILOT BURNER. When installation of the
media is complete the top of the Pilot Burner Protective Cover should be visible.

Filler Material
(material used below the fire ring)
There are a couple options when it comes to adding filler material to a fire
feature. For ‘shallow’ features such as the bowl at right it is recommended to
use landscape lava rock (3/4” chunk size) up to the level of the fire ring. This
lava rock is very inexpensive and is available at local hardware/nursery stores.
For ‘deep’ features it is recommended to first build a fake ‘floor’ in the feature
prior to adding the filler material described above. This will cut down on the
amount of filler material needed.
Notice in the photo at far right the top half of Pilot Burner
is elevated above the Filler Material – this is important.
Topping Material
(Large Chunk Lava Rock)
There are several options when it comes to topping material for a fire feature;
large chunk lava rock, fireglass and fire stones. In the photo at right we used
large chunk lava (2” to 3”) to cover the fire ring. This lava rock hides the
components of the fire feature while at the same time allowing plenty of
oxygen to mix with the gas coming from the fire ring. This lava rock is more
expensive than the “filler’ lava rock but is still fairly inexpensive and readily
available in the BBQ section of most hardware stores.

WARNING
Do not use any other material as filler/topping media inside fire features other than those listed below.
Using improper media inside a fire feature could result in damage to property or
injury to persons nearby due to media ‘popping’ or ‘exploding’ due to heat
