The AVI Hood System consists of three (3) major parts; the Main Canopy, the Shrouds,
and the Variable Frequency Drive (VFD) exhaust fan controller.
The Main Canopy serves to collect and transmit heat to the exhaust fan. It houses filters,
lights, and controller. The controller operates both the hood and ovens. The main canopy size is
dependent upon oven size.
The Shrouds assist the efficiency of the main canopy by entrapping heat. They are config-
urable for either side or end loading or unloading, and are easily removable for cleaning and main-
tenance.
The VFD converts input power to variable frequency three-phase output power to control
the speed of the exhaust fan. All electric utilities for the hood and exhaust fan connect through the
electrical box located on the front of main canopy. The capacitive touch buttons are located on the
Hood User Interface on the front of main canopy, and interlock the function of the hood and
oven(s). There are relays that provide interlocks for equipment such as, HVAC dampers, and/or
dedicated MUA units and there is a optional relay for fire suppression.
All AVI hoods are available pre-piped for fire suppression, allowing for simple, in-field
installations. For fire suppression detailed information see manual XD-9011 Fire Suppression In-
stallation for AVI Hoods and XLT Ovens.
The AVI hood was designed to conform to the requirements of IMC 2015 or current ver-
sion, which is a Type I hood. It was also designed to have optional fire suppression added to meet
requirements of NFPA 96 standard. This was done to allow XLT to better service the requirements
of the customer and the associated jurisdictions.
