INSTALLING THE
DUCTWORK
NOTE
THESE INSTRUCTIONS WILL FOLLOW THE PLANS MADE ON PAGE 2. START AT THE EXTERIOR AND RUN THE DUCT BACK TO THE RANGE HOOD.
FOR BEST PERFORMANCE OF YOUR RANGE HOOD, USE THE SHORTEST POSSIBLE DUCT RUN AND A MINI- MUM NUMBER OF ELBOWS.
NEVER VENT A RANGE HOOD INTO AN ATTIC SPACE BECAUSE A BUILDUP OF GREASE WILL BECOMEA FIRE HAZARD.
USE ONLY METAL DUCTWORK (DO NOT USE PLASTIC DUCT). ASSEMBLE SECURELY SO THAT IN CASE OF A GREASE FIRE ON THE RANGE, THE FIRE WILL BE CON- TAINED INSIDE METAL DUCT WORK.
IT IS A GOOD PRACTICE TO TAPE ALL DUCT CONNEC- TIONS, MAKING THEM BOTH SECURE AND AIR TIGHT.

VERTICAL DUCTING AND WIRING
(Through Cabinet Bottom)
BACK WALL
Use a saber saw to cut a hole slightly larger than duct so duct will line up easily with hood. Install casing strips on outside walls finished in siding. Assemble the duct work and tape all joints. Run duct work back to hood. Fasten wall cap to last section of duct and nail or screw cap to wall. Seal all around flange on wall cap with caulking compound. Make sure that enough duct runs into the room so that the duct will overlap the damper/duct connector by 3/4" when the hood is installed.
ROOF CAPS
Cut hole in roof slightly larger than duct so duct will line up easily with hood. Trim shingles around hole so that they will fit snugly around hood of cap when cap is installed. Assemble the duct work and tape all joints. Run the duct work down to hood. Trim duct parallel to roof pitch, leaving 3/4" of duct projecting above roof. Seal all around duct with roof cement.
Install roof cap, inserting back edge of cap under shingles. Seal around cap with roof cement and seal all nail heads and shingles which were cut or lifted.
Make sure that enough duct runs into the room so that the duct will overlap the damper/duct connector by 3/4" when the hood is put into place.
