A. Measuring the Appliance Region
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.
To measure the Appliance Region air velocity
rotate the Comfort Tuning Dial towards the red dot, counterclockwise to shut
off air to the Chef Region. Now measure the velocity from the MJGrill
perforated discharge towards the inside of the hood in the Appliance Region.
The measurement can be made with a Hot Wire Anemometer or Vane Axial
Velometer. The required air velocity is indicated below in Chart No. 4. If
the velocity is too high or low the MJ Blower must be adjusted to increase or
decrease the velocity to the Appliance Region.
