INSTALLATION INSTRUCTIONS

Ventadome Non Powered Model: V3092; 12VDC Powered Model: V3094

CAUTION
For general ventilating use only. Do not use to exhaust
hazardous or explosive materials or vapors.

1.

Locate ceiling joists, mark desired location between joists on
ceiling and roof. Cut 14-1/4" square opening through ceiling and
roof.

2.

Place sealant around bottom edge of roof mounting flange. Orient
the vent so the hinge is towards the vehicle front and insert vent
into the opening with the screen frame extending through the roof
cavity.
For standard installation: Mount vent to roof with appropriate
screws of sufficient length through the mounting holes in the flange
(#8 or #10 recommended).
For clamp-in installation: From the inside, install the four
(4) VB0492 clips (ordered separately) into the corners using
appropriate length #8 screws designed for use on plastic (ref hi-lo
type thread). Tighten screws until clips pull the vent flange down
against exterior roof providing a water tight seal; be careful not to
over tighten. Apply a bead of caulk or uncured rubber around the
perimeter of roof flange after installation is complete.

3.

On powered vents, remove screen frame and wiring compartment
cover if present. Make all electrical connections in accordance with
local and/or applicable codes (see wiring diagram below). Replace
wiring compartment cover and screen frame.

4.

Verify that the fan unit is free of debris and that the fan spins freely.
Place ceiling garnish trim collar portion into groove around the
screen frame. Drive #8 screws (max.) through the mounting holes
and tighten to ceiling. Be careful not to over tighten and distort
garnish.

Do not allow insulation, ceiling finishing materials, roofing
materials, or other debris to enter the fan area. Motor failures
due to debris are not subject to warranty coverage.

CAUTION
This fan unit has not been evaluated for suitability for
installation over tub or shower.
This fan unit is not intended for direct installation over range
