3 .6 Mounting the Vent Fan
This section describes the two installation options for
your vent fan.
• A vent mount installation is the standard,
recommended method for most Fan-Tastic Vent Fans.
See "Vent Mount" on page 11.
• A clamp-fan mount is recommended only for a roof
or wall that is less than 4 in. (102 mm) thick and
without a solid substrate to support a rooftop screw
installation. See "Clamp-Fan Mount" on page 12.
• Confirm the height of the trim garnish is correct for
the thickness of your roof or wall. See "Trim Garnish
Dimensions" on page 6.

1. Move the vent fan (AA) to the exterior roof opening.
2. Line the outside of the roof opening with a
compatible sealant, or place the gasket (BB) around
the opening.
If using sealant, for rubber roofs, use an EPDM-
I
compatible roof sealant.
3. Position the vent fan (AA) over the exterior roof
opening, making sure the sealant or gasket is
"sandwiched" between the bottom of the mounting
flange and the roof opening.
– When positioning the vent fan on the roof, the lid
hinge should be closest to the front of the RV.
– If positioning the vent fan on the side of the RV
(vertically), the lid hinge should be closest to and
parallel with the roof line.
4. Use the #8 self-tapping flat-head screws
(3/4"–1") (DD) provided to attach the vent fan to the
exterior roof opening.
5. Apply an all-weather sealant over the screw heads and
at the mounting flange where it meets the roof or side.
