This is the replacement Damper Assembly for the early model Phase I Appalachian Stoves. These stoves were Catalytic. Some models made prior to 1989, had two rectangular catalyst that were 1.875" x 6.875" x 2". ( SV3400 ) Some models had 4 Catalyst, 2 of them 1.875" x 6.875" x 2 ( SV3400 ) and then 2 cats that are 1.875 x 6.875 x 1 (SV3448 ). Catalyst Sold Separately.

This is a complete assembly to include the weldment with slide damper plate, Impingement plate, mounting brackets and screws, new damper rod with spring handle and tension pins.
