Step 2: Prepare The Venting System - Kenmore 721.67600 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 9, page 9.
WARNING-FIRE HAZARD
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 Figures 6 (31/4" x
10" duct) and 8 (6" round duct.)
Wall-venting If your oven is located on an outside wall on the first floor of your house, as in
Figures 5 (31/4" x 10" duct) and 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.

REMEMBER AS YOU INSTALL THE
VENTING:
• Keep the length of the ductwork and the
number of elbows to a minimum to
ventilate your oven efficiently.
See examples on page 9.
• Keep the size of the ductwork the same.
• Do not install two elbows together.
• Use duct tape to seal all joints in the duct
system.
• Use caulking to seal the exterior wall or
roof opening around the cap.
