Hearthstone insulation blankets, firebrick panels, secondary air tubes, door gasket kits, and combustion system components.

Why Choose the Lynn Manufacturing 2442A Baffle Board Kit?
A damaged or worn baffle can reduce heat output, increase emissions, and disrupt proper airflow inside the stove. Replacing your baffle system with the 2442A kit restores secondary combustion efficiency, improves heat retention, and helps maintain clean-burning, high-performance stove operation.

Installation Instructions:
Allow the stove to cool completely before servicing.
Remove internal components as needed to access the baffle area.
Carefully remove the existing baffle boards.
Clean and inspect support ledges.
Install the new 2442A boards in the correct orientation.
Ensure proper alignment and full support.
Reassemble components and verify secure placement before operation.

Installation Tip:
Never operate your stove with cracked or missing baffle boards. Properly functioning baffles are critical for efficient combustion and protecting internal stove components.

Restore efficiency, improve combustion, and extend the life of your stove with the Lynn Manufacturing 2442A Hearthstone Castleton I Baffle Board Kit—engineered for durability, safety, and dependable high-temperature performance.
