MOUNT INTAKE HOOD

Install a weather tight hood with a bird screen.
Cut a hole in the exterior wall that is large enough to fit 6" insulated flexible duct through with minimal compression of the insulation. Pull the duct
through the hole and attach the flex duct to the collar of the hood. Use metal foil tape or a plastic zip-tie to secure the duct to the collar. Pull the
insulation and vapor barrier over the duct and tape it to the collar.
IMPORTANT: The end of the insulation must be sealed to prevent condensation from forming inside the insulation. If a plastic zip-tie is used to
secure the insulation to the hood collar, also tape the end to seal it against condensation problems.
Press the hood against the outside wall and secure in place with screws; seal around the perimeter of the hood with caulk.
