STEP 2: Prepare The Venting System
THIS OVEN MUST BE PROPERLY VENTED!
NOTE: The ductwork you need for outside ventilation is not included with your oven. The standard ductwork
fittings and length are shown in Figure 10, page
8
.
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 If your oven is located on an outside wall near the roof, as in Figure 7 (3 1/4" x 10" duct) and
Figure 9 (6" round duct.)
Wall-venting 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.)
Room-venting 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 the ductwork and the number
of elbows to a minimum to ventilate your oven
efficiently. See examples on page
8
.
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.
