Hearthstone Wood Stove Baffle Board For The Heritage 8020 (You may need to replace blanket: 3120-210 when changing this baffle).  The baffle board helps by holding heat in the firebox, causing the reburn tubes to reach extremely high temperatures.  It also stops the flue gases from quickly exiting the stove and forces them to travel across the tubes allowing reburn to take place. 

Note: Fits Hearthstone Heritage Wood Stoves Model 8020.

Heritage 8021 uses 2437A.

Heritage 8022 uses 2438A.

Assembly Instructions For Hearthstone Wood Stove Baffle Board (Heritage 8020): 3120-721-AMP

Install Instructions:

1.) Locate the baffle boards (On some stoves the boards can be removed by pulling out the cotter pins, angling the board, and sliding it out past the re-burn tubes. On others, you will have to remove the top casting to gain access to this area).

2.) Reposition the new boards in place (Reinstall any previously removed cotter pins or retainer clips) and reinstall the top casting if previously removed.


Helpful Tips:

It is important to inspect the baffle board on a regular basis. Missing pieces or cracks in the baffle may reduce how effectively the reburn system works. If you notice signs of deterioration as previously mentioned the board should be replaced.
