• Remove existing vent and mounting deck plate
• For a 4" vent: Confirm the existing opening is cut to 4-3/4" (121mm)
in diameter for a deck mount installation, or 4-1/2" (114mm) for a
hatch mount installation.
For a 3" vent: Confirm the existing opening is cut to 3-3/4" (95mm) in
diameter for a deck mount installation, or 3-1/2" (89mm) for a hatch
mount installation.
Ensure the existing opening is clean in preparation for install.
• Reference
“INSTALLING INTERIOR TRIM RING” of the new
installation instructions located previous in the instructions.
Continue to follow the installation instructions until completion.
There are three (3) important factors that must be addressed to
insure a good base plate installation:
1. Make sure the base plate is properly caulked when fastening it to
the deck or hatch. We recommend using a 1/4" to 1/2" (7mm-12mm)
wide bead of silicone sealant. The sealing gasket (included) may
also be used if the vent is being mounted on a flat surface without
curvature.
2. The installation hole must be cut to 4-3/4" (121mm) in diameter
for a 4" vent or 3-3/4" (95mm) in diameter for a 3" vent, so that the
surface around the base plate is not distorted and the interior trim
ring will fit properly. Measure carefully to cut the properly sized hole.
3. When installing the vent on a cambered surface, make sure you
do not tighten the fasteners too much; this will distort the base plate
and may cause the vent to leak.
MAINTENANCE
Your Day/Night PLUS vent is a maintenance-free ventilator.
However, it is very important to keep the nine drain holes around
the edge of the base plate clear at all times. Failure to do so will
allow water to accumulate in the base and possibly enter the cabin.
