Important Note:
This product is made from Superwool Plus, a next-generation pyro-ceramic insulation material designed for high-temperature stove applications. It is not tempered glass. This material is engineered to withstand direct flame exposure and continuous high heat while maintaining structural integrity.

Pairs Well With:
Hearthstone firebrick panels, secondary air tubes, door gasket kits, and combustion system components.

Why Choose the Lynn Manufacturing 2440C Baffle Kit?
A worn or damaged baffle system can reduce stove efficiency, increase emissions, and allow excessive heat loss. Replacing your complete baffle system with the 2440C kit restores proper airflow, improves secondary combustion, and helps maintain clean-burning, high-efficiency stove operation while protecting internal components.

Installation Instructions:
Allow the stove to cool completely before servicing.
Remove internal components as needed to access the baffle area.
Carefully remove the old baffle board and insulation blanket.
Clean and inspect support ledges and surrounding areas.
Install the new baffle board in the proper orientation.
Place the insulation blanket above the board as designed.
Ensure full coverage and proper fitment.
Reassemble components and verify secure placement before operation.

Installation Tip:
Always replace the insulation blanket together with the baffle board for maximum efficiency and longer stove life. Mixing worn and new components can reduce performance.

Restore efficiency, improve combustion, and extend the life of your stove with the Lynn Manufacturing 2440C Hearthstone Heritage IV Baffle Board & Blanket Kit—engineered for durability, safety, and dependable high-temperature performance.
