DUKE CHAIN BROILER & DUKE HOOD EXHAUST HOOD
TWO – TWO FLOW POINT NOZZLE (P/N 13729)
The Duke Chain Broiler and Hood combination is a special design just for the Duke product. The hood and
broiler are each fitted with a catalyst to decrease the emission of grease laden vapors into the exhaust duct
system. The hood comes pre-piped for the installation of the fire suppression nozzles. This unique appliance
operates at an extremely high temperature in order to cook large quantities of frozen burgers in a short span
of time.
The protection of this unit is accomplished by using two (2) Nozzles P/N 13729 installed in the piping provided
so that it will spray agent into the catalyst as illustrated. A third nozzle P/N 16416 is installed for duct
protection of the 8” diameter exhaust duct.
If no catalyst is used the same protection is required. The addition of a damper on top of the broiler catalyst
does not change the protection required for the unit. Due to the extreme heat of the appliance close
inspection of the nozzles is to be performed at each six month service interval. Nozzle replacement is
required at the signs of any nozzle deterioration.
