Why Choose the Lynn Manufacturing 2427A Baffle Board?
A damaged or worn baffle can reduce stove efficiency, increase emissions, and allow excessive heat loss. Replacing your baffle with the 2427A restores proper airflow, improves combustion efficiency, and helps maintain clean-burning performance while protecting your stove’s internal components.

Clean and inspect support ledges.
Install the new 2427A board in the correct orientation.
Ensure it sits flat and is fully supported.

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