A common scenario of how a kitchen exhaust fire starts is this:
A flame flares up on the stove or fryer
The fire contacts the filters above the cooking equipment on the kitchen hood.
The filters ignite.
Since the exhaust fan is on, drawing air into the hood, through the filters, and up the duct, the flame on the filters is pulled into the duct.
If significant grease residue exists on the duct interior, this can act as a fuel and the fire spreads up the duct, perhaps all the way into the fan.
