THIS OVEN MUST BE PROPERLY VENTED!
You may vent your oven in one of three ways. However, do NOT vent into a wall cavity, an attic, or an unused
area.
• Roof-venting
• Wall-venting
• Room-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.)
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.)
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.

REMEMBER AS YOU INSTALL THE
VENTING:
• Keep the length of tile 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.
