One crumb pan is located at each end of the conveyor. L. Gas Burner: Heats air, which is then projected to the air fingers by the blowers. M. Blowers: Project hot air from the burner to the air fingers. N. Air Fingers: Project streams of hot air onto the food product. C,D.
SECTION 2 - INSTALLATION Perform a gas leak test. Test for correct air supply. Test for proper combustion and gas supply. Check that the ventilation system is in operation. WARNING Keep the appliance area free and clear of combustibles. WARNING The oven must be installed on an even (level) non-flammable flooring and any adjacent walls must be non-flammable. Recommended minimum clearances are specified in the Description section of this Manual.

SECTION 2 - INSTALLATION III. VENTILATION SYSTEM CODES SUPERSEDE THE RECOMMENDATIONS SHOWN IN THIS MANUAL. The rate of air flow exhausted through the ventilation system may vary depending on the oven configuration and hood design. Consult the hood manufacturer or ventilation engineer for these specifications. IMPORTANT ENGLISH Where national or local codes require the installation of fire suppression equipment or other supplementary equipment, DO NOT mount the equipment directly to the oven.
SECTION 2 - INSTALLATION IV. ASSEMBLY Base Pad, Legs, Casters, and Stacking 1. Install the top panels in place on the top oven cavity. Follow the instructions provided with the top panels. 1/2" flat washer 2a. Legs/Casters Installation - Single and Double Ovens Install one leg extension to each corner of the base pad using the 1/2"-13x1-1/4" bolts, 1/2" flat washers, and 1/2" lockwashers supplied in the Installation Kit. See Figure 2-3.
SECTION 2 - INSTALLATION ENGLISH 1. Lift the conveyor and position it in the oven as shown in Figure 2-9. 2. Continue moving the conveyor into the oven until the frame protrudes equally from each end of the oven (about 18"/ 457mm). 3. Check that the retainers located on the underside of the conveyor frame rest firmly against the lower end plugs, as shown in Figure 2-9. 4.
SECTION 2 - INSTALLATION 1. Refer to Figure 2-12 to determine the correct locations of the crumb trays. 2. Install the crumb trays underneath the conveyor as shown in Figure 2-12.
