GE 36, 48 Use And Care Manual page 8

General
The grill section consists of a large cast iron
burner, a series of stainless steel heat baffles, a
information
bed of natural lava rock and a porcelain
enameled heat retaining grill rack.
Each burner is rated at 20,000 BTU.
Below each burner is a stainless steel heat baffle
which reflects usable heat upward into the
cooking area and reduces the temperature of
the drip pan below.
The cast iron grill burner encompasses the
entire cooking area and is top ported to operate
cooler and last longer.
Above the burners are stainless steel radiants
which support the lava rock and protect the
grill burner ports from blockage.
Lava rock
The grill is supplied with natural lava rock.
Because of the porosity of natural lava rock it is
superior in its ability to capture heat as it rises
from the grill burners. It also possesses the
thermal mass needed for professional results.
Flare-ups are controlled because the lava
radiant keeps grease from getting to the flames
and igniting. The intense heat produced by
this system produces true grilled flavor as fats
and juices are brought to the surface of the
food and caramelized.

Heat baffle
Place lava rocks in a single layer on top of the
radiant located under the grill rack. It is
important to distribute the rocks evenly over
the stainless steel radiant tray without leaving
any large gaps. Uneven distribution of rocks
and air gaps can cause localized "hot" and
"cold" spots which could result in
unsatisfactory cooking performance.
