Step 2: Prepare The Venting System - Kenmore SPACEMASTER 85210 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 Sears recommends are shown in Figure 7, page 9.
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 Figures 5 (3 1/4" x 10" duct)
and 6 (6" round duct.)
Wall-venting If your oven is located on an outside wall on the first floor of your house, as in
Figures 4 (3 1/4" x 10" duct) and 6 (6" round duct.)
Room-venting If your oven is located on an inside wall on the first floor of your house.
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.
