Hood Operation
NOTE
When XLT Ovens are outfitted with AVI Hoods, the main switch on the oven is dis-
abled and no longer operates. The switch on the AVI Hood overrides the oven switch.
Hood Initial Start-Up
All AVI Hoods are function tested at the factory. Operation is verified, and adjustments
are made to ensure proper operation. However, field conditions are sometimes different than fac-
tory conditions, such as voltage and CFM pressure. These variables make it necessary to have an
authorized service technician verify operation and make field adjustments if needed. The follow-
ing items must be checked and verified to meet the specifications and requirements stated in this
manual prior to the hood being commissioned:
 Length of duct run.
 Number of bends in duct.
 Correct fan rotation.
 Balanced make-up air.
The following Initial Start-Up Checklist must be completed at time of installation, signed by the
Customer and returned to XLT Ovens to initiate Warranty Policy.
