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 Figures 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. cabinet Wall Venting _.
