Installation Guide

UV-48 Universal Vent

Installation Instructions

To properly install this Universal Dormer Vent, please follow these instructions.

1) When used as a Roof Exhaust Vent, cut a 1.5” x 46” slot just below the ﬁrst row of shingles using

the following chart. (See View 1). When used as a Roof Intake Vent, cut the slot 1 foot up from

the bottom edge of the roof, from there installation instructions are the same.

Please note: if more than one Universal Vent is being installed, then the VENTS (not the slots)

must be spaced 4 inches apart when installed, to allow for roof water drainage.

2) Apply sealant under the top ﬂange and along the side edges (See View 2). Then place the top

ﬂange under the shingles placing it so that the slot is centered under the Universal Vent. Be sure

the Vent is correctly aligned with the slot before continuing. (See View 3)

3) When the Universal Vent is in its ﬁnal position, the bottom ﬂange should rest on top of the shin-

gles to ensure correct drainage. Do not use sealant on the bottom ﬂange. (See View 2)

4) Attach the Universal Vent to the roof using (#8 x 1") screws

on the bottom ﬂange, 6 " apart. (See
