Ceiling Installation

LOCATING & MOUNTING FAN

STEP 1 — The A24DD fan mounts on ceiling joists that are spaced 16” O.C. Fan should be located in center of house, preferably in hallway or corridor. This will allow air to be drawn through all parts of living space. (See Fig. 1.) Determine tenta- tive location of fan and proceed as shown below.

STEP 2 — Determine joist direction and locate center joist in ten- tative fan opening. Lightly pencil a rectangular 30 1/2” x 33 1/2” opening on ceiling below where shutter is to be located. Make sure 33 1/2” side is parallel to joist direction. Check to be sure that enough clearance area is available on ceiling for overlap of shutter flanges (1 1/2” on all sides). Drill two small pilot holes close to center joist, (one on either side) to indicate where hole will be centered. (See Fig. 2.)

STEP 3 — Now clear insulation and find pilot holes in attic. Tentatively lay out same rectangular hole as on ceiling below. Adjust location of hole if necessary to insure a minimum verti- cal clearance from roof rafters of 18” above fan (Fig. 3).

STEP 4 — Carefully cut hole in ceiling (Fig. 4), being careful not to cut into center joist. Cut along both sides of the center joist, leaving the 1 1/2” (approximately) strip of ceiling sheet rock cov- ering the center joist.

If you have 2 x 4 joist construction, the joists on which the fan will be mounted must be built up to 2 x 6 joist height. This can be done very easily at this point by nailing (3) 2 x 2 furring strips 38” long to the top of the joists, one on each joist.

STEP 5 — Remove adhesive backing from the 1/2” x 1/2” gas- ket material and attach to the bottom flanges of fan which rest on the joists. (Fig. 5) Now place fan on joists. Install grommet in bracket (Fig. 5) and attach on each end of fan, using two of the short screws provided. Position fan over opening so that grom- mets are resting against center joist. Attach fan and brackets to center joist with the two long wood screws and flat washers. Do not crush grommet when tightening screws.
