In today's tightly constructed homes, sometimes there is not enough air
coming into the house to replace the warm air that goes up the chimney when a fire is burning in your fireplace. When that happens, the fireplace smoke comes back into your room
instead of going up into the chimney, creating a drafting problem and giving you a smoky fireplace!
This Air Supply Ventilator allows filtered, fresh air from the outside into your home,
giving your wood burning fireplace, vented gas appliances, or vent-free gas appliances sufficient air. Made of durable ABS molded polymer, the Air Supply
Ventilator can be painted with latex paint to match your home's exterior (on the louvered grill side) and interior (on the insulated vent cover side).
The Air Supply Ventilator has a manual airflow adjustment and a washable, outside
noise blocking air filter that filters dust particles exceeding 10 microns. It can be installed in about 30 minutes, and instructions, all hardware, and caulking are
provided. The Air Supply Ventilator requires no electrical wiring, batteries, or ductwork. Placed in an exterior wall up to 14 inches in depth, the Air Supply
Ventilator can be opened when you have a fire going in your fireplace and closed at other times.

When your fireplace back-puffs, open a window a bit. If the smoke goes up
the chimney instead of into the room, this Air Supply Ventilator is a good solution to your problem.
The area (length multiplied by width) of your fireplace opening should be no
more than ten time the area of the flue coming out of your chimney. If your fireplace opening is more than ten times the area of your flue, a Smoke Guard
will be a better solution, as the Smoke Guard effectively reduces the size of your fireplace opening.
