ABSTRACT:
A spacer clip for maintaining the coaxial spacing of the walls in a multiple wall chimney. A plurality of spacer clips are circumferentially positioned within the annulus between the walls. The clip attaches to the outer wall and includes a biasing arm which engages the inner wall to maintain the spacing between the walls. The biasing arm of the clips may be retracted to facilitate insertion or removal of the inner wall from within the outer wall.
