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 (3 1/4" 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.
