Island Hoods
1. Protect the cooktop with a furniture pad or con-
sider building a worktop straddling the counter.
Center and square hood to actual location of
cooktop. Leading edge of hood should align with
front cooking element, NOT front of cooktop. Us-
ing a plumb line, "project" the four corners of the
stack to ceiling and mark stack outline.
2. Cut opening in ceiling 2’ - 3’ wider than stack. If
there is an attic or crawl space above hood, hang-
ing frame can be built from above. If there is a
carpeted room above hood, peel back carpeting
and cut access panel through sub-floor to build
hanging frame. Build hanging frame with 2 x 4’s .
Header off ceiling joists as necessary to frame
hood stack.
3. Pre-drill stack top with holes for attachment to
hanging frame. 6” of stack top should penetrate
ceiling line for secure anchorage.
4. Lift hood and slide exhaust stack up into hanging
frame. Position hood at desired mount height. Span the island with 2 x 4’s resting on scaffolding, for
example, to prop up hood in position.
5. Level hood and temporarily tack in position to hanging frame with sheet rock screws. Firmly attach
stack to hanging frame with bolts, lock washers and nuts. If running duct work through joist bay, cut
away the side above the ceiling line that will allow an adjustable elbow to turn into the bay.
6. If overall height of hood would position the bottom below recommended clearance above cooking
surface, excess stack may be cut off.
NOTE 1: Stainless Steel may be cut in several ways - POWER JIG SAW using carbide blades
designed specifically for ferrous or hardened metals (24 teeth per inch) ANGLE GRINDER or
heavy duty angle drill using an abrasive type aluminum oxide, diamond edge, or carbide wheel.
If using a jigsaw, he cutting process will be slow, generate a lot of heat, and may require several
saw blades. "Blueing" or discoloration of the stainless steel may occur during cutting.
NOTE 2: When drilling use cobalt drill bits for stainless. Use 1/8" bit for pilot hole and enlarge as
needed with "Step-Drill" or progressively larger bits.
7. Replace sheetrock. Any gaps around stack can be filled with paint-ready caulking and painted or
framed with molding. Optional decorative ceiling cover plate is offered for difficult to patch wood ceiling.
