3.Use
4.Cut out duct opening in wall or cabinet with saber saw or keyhole saw.
5.Center hood in installation opening and trace keyhole slots onto wood filler strips on cabinet bottom.

INSTALL THE DUCTWORK
(This section for UXT2030AA, UXT2036AA, UXT3030AA, and UXT3036AA hoods ony. UXT4030AA and UXT4036AA hoods skip this section and go on to "Install Range Hood".)
NOTE
These instructions will follow plans made on Page 2. Start at the exterior and run ductwork back to the range hood.
For best possible performance, use the shortest possible duct run and a minimum number of elbows. Do not vent a range hood into an attice space. A buildup of grease in the attic could become a fire hazard.
Use only metal ductwork. DO NOT USE PLASTIC DUCT. Assemble duct run securely so that in case of a grease fire on the range, the fire will be contained inside metal ductwork.
Tape all duct connections.
2.Follow appropriate directions below for type of duct run you install.
a.) Wall Cap Discharge; (FIG. 7) Use saber saw or keyhole saw to to cut hole slightly larger than duct size used so that duct will line up easily with damper/duct connector on hood. Install casing strips if cap will be installed on siding. Attach required amount of duct to wall cap and run duct back to hood. Fasten cap to wall and caulk well.
FIG. 7
b.) Roof Cap Discharge: (FIG. 8) Cut a hole in roof slightly larger than duct size being used. Run ductwork down to hood location. Leave 3/4" of duct projecting above roof surface on high side.
Trim duct parallel to roof pitch and seal all around duct with roof cement.
Carefully trim shingles and slide back of roof sheet under shingles. Nail roof sheet to roof under shingles at top two comers and two sides. Nail sheet directly to roof in four places at bottom.
Using roof cement, seal all nail heads and shingles which were cut or lifted. Do not seal bottom edge of roof sheet.
