Air Supply Ventilator

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 air filter. It can be installed in about 30 minutes, and instructions are provided. The Air Supply Ventilator requires no electrical wiring, batteries, or ductwork. Placed in an exterior wall up to 6 inches in depth, the Air Supply Ventilator can be opened when you have a fire going in your fireplace and closed at other times.
How Do I Know If An Air Supply Ventilator Will Cure My Smoky Fireplace Problem? Take this Quiz to diagnose your fireplace drafting problem to see if the Air Supply Ventilator will best solve your problem.

• 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.
• If your fireplace only back-puffs on windy days, a Vacu-Stack chimney cap is the appropriate solution. Depending on your flue, you will need a Vacu -Stack for a round flue, a Vacu-Stack for an air-insulated flue, or a Vacu-Stack for a masonry flue.
• 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.
• If your fireplace opening is correctly sized for your flue but your fireplace is smoky even on windless day and even when you open a window a bit, an Exhausto Fan for round flues or an Exhaust Fan for square or rectangular flues is the solution for your smoky fireplace.
