The Appliance Region and Chef Region discharge is called the
MJGrill. The MJGrill is manufactured as a single component shown
on the left in Figure 28. The MJGrill includes the Appliance Region
discharge, Chef Region discharge, and a adjustable Comfort Tuning
Dial. The Comfort Tuning Dial proportions the amount of air to the
Chef Region.
The Comfort Tuning Dial on the MJ Grill has
two colored dots; red and blue. The Comfort
Tuning Dial proportions the volume of air to
the chef. Turning the Comfort Tuning Dial
towards the red dot provides less air to the
Chef Region and turning the Comfort Tuning
Dial towards the blue dot provides more air
to the Chef Region.
