Replacement Baffle Board Kit for Hearthstone Mansfield III 8013 (2022 and newer) Wood Stoves. The Kit includes two 3120-012 baffles. The total measurements are 21-1/8″ x 15-3/8″ x 1″ when mated with shiplap joint.
Baffles in wood stoves and inserts are required to be in good condition to burn efficiently and meet EPA emissions regulations. The baffle, when working correctly, creates a secondary high temperature burn zone to reduce smoke emissions. Over time, it is normal for baffles to deteriorate and they can be easily broken during routine maintenance. Stoves with broken or missing baffles will burn less efficiently, smoke more, and not comply with emissions regulations. To ensure your stove is working efficiently and safely, inspect your baffles yearly and replace them when they have visible damage such as cracking or missing material.
