Hood Appliances VS Appliance Region Face Velocity
Chart No.5
B. Adjusting the MB Blade to change velocity at the appliance region.
Open the MB Blade Face Discharge Grill on the front of the MB
plenum located above the MJGrill that requires adjustment. The MB
Blade perforated discharge grill is secured with four (4) Philips
screws. Once the MB Blade discharge grill is removed in the center
of the MB Blade is a threaded MB Blade adjustable Rod. To increase
the velocity to the MJGrill below, rotate the threaded MB Blade Rod
clockwise. To decrease the velocity to the MJGrill below, rotate the
MB Blade Rod counter-clockwise. Measure the MJGrill discharge
velocity after each adjustment until the correct velocity as indicated in
Chart No. 4 is achieved.
C. Adjusting the air velocity to the Chef Region
The amount of air directed to the Chef Region is a personal decision. When commissioning an
MB hood system we recommend the following:/
Heavy Appliances, Charbroilers, Woks: Rotate the Comfort Tuning Dial towards the blue dot to
fully for maximum Chef air.
Medium Appliances, Griddles, and Ranges: Rotate the Comfort Tuning Dial towards the blue
dot about three or four rotations clockwise.
Light Appliances, Ovens, and Kettles: Rotate the Comfort Tuning Dial towards the red dot to
fully close the air to the Chef Region.
