General Guidelines for FirePits:
1) The burner
should be installed with the holes (burner
ports) pointed downward for better flame
dispersion and to avoid the burner
filling up from rainwater (which will decrease the life of the burner
2) The burner
should be covered with volcanic ash
(or fire glass) from about 1" below the bottom of the burner
to 1" to 2" above the top surface of the burner
to provide a level platform for stacking our logs, FireStones, FireBalls or FireShapes. The volcanic ash
(or fire glass) also serves to diffuse the flame
to increase the life of the logs, etc. Direct flame
straight out of the burner
impinging onto the logs will break the cementitious bonding that keeps the logs intact during normal use. Volcanic ash
and fire glass do not clump like sand can do (resulting in high flame
in one area, low on another), and their porosity allows for better mixing with secondary combustion
air for a somewhat cleaner burn.
3) Match lighting is preferable for outdoor FirePits, due to uncontrollable and unpredictable weather issues (wind, rain, snow).
a) If you desire to use a control system, do not use a standing pilot
control, as it will provide you with nuisance shut down. Use a pilot-on-demand electronic ignition control.
b) With an electronic ignition system
, you still have a
pilot. The pilot flame
must be shielded so that it fully
engulfs the sensor electrode at all times during operation. If
the pilot flame
does not remain constantly on the sensor, the main
will cycle on and off as the pilot flame
touches and pulls away
from the sensor electrode.
