Hearthstone 90-53220 Heritage/Mansfield Outside Air Adapter

Description

The HearthStone Outside Air Starter provides a dedicated connection for supplying outside combustion air directly to compatible HearthStone wood stoves. Designed specifically for Mansfield and Heritage models, the adapter connects to the stove’s combustion air inlet and provides a 3-inch connection for outside-air ducting.

Bringing combustion air in from outside can be especially useful in tightly constructed or well-sealed homes where adequate indoor combustion air may be limited. It can also help prevent the stove from drawing already-heated room air for combustion.

This genuine HearthStone accessory is designed for proper fitment with compatible Mansfield and Heritage wood stoves and provides a clean starting point for an outside-air installation.
