The unit is shipped in a manner that is stacked together, but the hood
and base may not be attached, to facilitate access for installation. The
installation specifics vary with the design of roof curbs that the
hurricane resistant ventilator is to be mounted on. Modification of the
assembly order may be necessary to have access to the restraint
components and complete the installation. The following requirements
must be met for the installed ventilator to meet the windload and impact
resistance specifications.

1) Complete the installation of an approved roof curb. Recommended
methods are; a) Concrete Surface - ¼”-20 Hilti Kwik Bolt II w/ 2”
embedment, 18” C-C spacing and 6” from ends, provided by others, or
b) Steel Structure - ¼”-20 x 1 hex head bolt w/ locknut and washer, 18”
C-C spacing and 6” from ends, provided by others.

2) The installer is responsible for providing mounting points (5) for the
lower eye bolts on the roof structure. 2x2x1/4” steel angle or similar
material should be used.

3) Install lower eyebolts (6) on anchor points (5) and attach the 1/8” dia.
SS cable (7) (2’ long) to the lower eyebolts with the clamps provided.

4) Attach the upper angle clips (3) (2 x 1.5 x1/8” x 4” long aluminum
angle) to the inside lower edge of the penthouse assembly using two
#12 self-drilling metal screws per angle. Two should be installed on
each side, 15” maximum from the corner (sides less than 15” inside
require one per side).

5) Install the extended sill (2) over the curb and center it. Attach the fan
base to the extended sill if not already done so. Attach using ¼”
fasteners on 15” centers.

6) Install the penthouse (1) over the extended sill. Drill through the
upper angle clip, the extended sill and the lower angle clip in two
