Hood should extend about 6 beyond all sides of the appliance The hood should be connected to an adequate exhaust duct or system When ovens are installed in locations with low ceilings care must be taken to insure proper clearance for the flue products Lack of this clearance above outlet of rear flue piping will interfere with heat circulation in the oven and could create a fire hazard condition Refer to NFPA 96 Do not permit fans to blow directly at the oven and wherever possible avoid open windows next to oven sides or back and wall type fans which create air cross currents within the room It is also necessary that sufficient room air should be allowed to enter the room to compensate for the amount of air removed by any ventilating system Otherwise a subnormal atmosphere pressure will occur affecting oven operation adversely and causing undesirable working conditions A properly designed and installed hood will act as the heart of the ventilating system for the room or area in which the oven is installed and will leave the oven independent of changing draft conditions INSTALLATION INSTRUCTIONS Cont d RECOMMENDED USE OF CONTROLS IN DETAIL C FOR ROAST AND HOLD OVENS 1 MOISTURE VENT DAMPER NOT SHOWN Pull damper knob out to open damper releasing excess moisture generated while cooking products with high moisture content Close damper when dry products are being cooked Intermediate adjustments permit selec
