TECH TIP
Vent Installation Explained Installation
Marinco® Ventilation Installation Systems Snap-In Deck Plate Installation The 12V vent, 12V combo vent and cowl vents use the Marinco Snap-In deck plate system. The snap-in system allows the easy exchange of any snap-in part for upgrading or convenience, as well as the use of a snap-in cover that completely seals the deck plate making it water tight. Direct-To-Deck Installation The Day/Night Plus, MiniVent 1000 and AirVent 500 are designed to be installed directly to the deck without the requirement for a deck plate. All of these vent systems have built-in shut- off dampers that operate from below.
All Marinco® ventilation products include clear, easy-to-understand installation instructions. These instructions address all of the key factors of a professional installation, such as: • Proper hole measurement and cutting procedures • Proper deck plate installation • Use of sealants to waterproof your vent installation • Installing vents in hatches • Installing vents in “cambered” or slightly curved decks Use of interior trim rings to “dress up” the cabin The high quality level of Marinco Ventilation products must be combined with a sound installation to guarantee that your vent performs in all conditions. Marinco will make sure that your installation will be easy and successful so that you can enjoy the benefits of installation for a long time to come.
