STEP 2: Prepare The Venting System NOTE: The ductwork you need for outside ventilation is not included with your oven. The standard ductwork fittings and length are shown in Figure 10, page 8. wW A R N I N G THIS OVEN MUST BE PROPERLY VENTED! You may vent your oven in one of three ways. However, do NOT vent into a wall cavity, an attic, or an unused area. Roof-venting If your oven is located on an outside wall near the roof, as in Figure 7 (3 1/4" x 10" duct) and Figure 9 (6" round duct.) Wall-venting If your oven is located on an outside wall of your house, as in Figure 6 (3 1/4" x 10" duct) and Figure 9 (6" round duct.) Room-venting If your oven is located on an inside wall of your house, as in Figure 8. NOTE: If you choose the rear exhaust method (roof or wall-venting), be sure there is enough clearance within the wall for the exhaust duct.
