Why Choose the Lynn Manufacturing 2434A Baffle Board?
A worn or damaged baffle can reduce heat output, disrupt airflow, and increase emissions. Replacing your baffle with the 2434A restores proper combustion, improves heat retention, and helps maintain efficient, clean-burning operation while protecting your insert’s internal components.

Installation Instructions:
Allow the insert to cool completely before servicing.
Remove access panels and internal components as needed.
Carefully remove the existing baffle board.
Clean and inspect support ledges.
Install the new 2434A board in the correct orientation.
Ensure it sits flat and is fully supported.
Reassemble components and verify proper placement before operation.

Installation Tip:
Never operate your insert without a properly installed baffle board. Doing so can reduce efficiency and damage internal components.

Restore efficiency, improve combustion, and extend the life of your insert with the Lynn Manufacturing 2434A Hearthstone Clydesdale Baffle Board—engineered for durability, safety, and reliable high-temperature performance.
