I 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.

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.
