Why Choose the Lynn Manufacturing 2900C Baffle Kit?
A worn or damaged baffle system can reduce heating efficiency, disrupt airflow, and increase emissions. Replacing your baffle board and insulation blanket together with the 2900C kit restores proper combustion performance, improves heat retention, and helps maintain clean-burning fireplace operation while protecting internal components.

Installation Instructions:
Allow the fireplace 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 proper alignment and full coverage.
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 fireplace life. Mixing worn and new components can reduce performance.

Restore efficiency, improve combustion, and extend the life of your fireplace with the Lynn Manufacturing 2900C RSF Baffle Board & Blanket Kit—engineered for durability, safety, and dependable high-temperature performance.
