Step 2: Prepare The Venting System - Kenmore 721.80494 Installation Instructions Manual

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 9, page 9.
THIS OVEN MUST BE PROPERLY VENTED!
You may vent your oven in one of three ways:
Roof Venting If your oven is located on an outside wall near the roof, as in Figure 6 (3-1/4" x 10" duct) and
Figure 8 (6" round duct.)
Wall Venting If your oven is located on an outside wall on the first floor of your house, as in
Figure 5 (3-1/4" x 10" duct) and Figure 8 (6" round duct.)
Room Venting If your oven is located on an inside wall of your house, as in Figure 7.
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.
