True North 4-Inch Outside Air Adapter for TN20 and TN25C Wood Burning Stoves

True North 4-Inch Outside Air Adapter for TN20 and TN25C Wood Burning Stoves

The True North 4-Inch Outside Air Adapter is designed to connect compatible TN20 and TN25C wood-burning stoves to an outside combustion air supply. It allows the stove to draw fresh air from outdoors rather than relying solely on air inside the home.

This adapter accommodates a 4-inch air duct and supports outside air installations through the floor or an exterior wall, depending on the stove base configuration. For leg models, the adapter attaches beneath the stove; for pedestal models, it attaches to the back of the pedestal when air is supplied through a wall.

The adapter is required for mobile-home installations and optional for typical residential installations unless local building codes require it. A compatible 4-inch metal duct and approved exterior air inlet cap or other code-compliant intake arrangement are needed separately to complete the installation.
