When installed, minimum clearance from combustible and non-combustible construction must be 2.5"
(63.5 mm) at the sides and 2.5" (63.5 mm) at the rear.
The installation location must allow adequate clearances for servicing and proper operation.
A minimum front clearance of 36" (914.4 mm) is required.
Do not obstruct the flow of combustion and ventilation air. Adequate clearance for air openings into
the combustion chamber must be provided. Make sure there is an adequate supply of air in the room
to replace air taken out by the ventilating system.
Information on the construction and installation of ventilating hoods may be obtained from the
standard for "Vapor Removal from Cooking Equipment," NFPA No. 96 (latest edition), available from
the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
The ventilation hood should extend 6" (152 mm) minimum past the oven on the front, back, and each
side of the conveyor belt.
Exhaust: Approximately 2000 CFM required for double stacked ovens.
Approximately 1500 CFM required for single oven.
Make-up air should be 65% to 80% of the exhaust air rating.
Do not permit fans to blow directly at the oven. Wherever possible, avoid open windows next to the
oven. Avoid wall-type fans which create air cross currents within the room.
