Do I need an outside air kit for my pellet stove?
The use of an Outside Air Kit may not be required in certain cases, but it is highly recommended in all installations. An Outside Air Kit feeds uninterrupted combustion air into your appliance from outside your home, helping to maintain proper air/fuel balance and ensure even burning.
Though these kits are not required in every installation, they may be required for your home. Outside Air Kits are required for all mobile/manufactured homes, and wherever local building codes require. To learn about the specific requirements in your area, contact your local Harman dealer.
