When design parameters do not allow for a vertical chimney installation, Offset Blocks offer the ability to move the chimney to the side, allowing it to pass objects, such as another fireplace, positioned above the firebox.
A non-combustible column under every fifth block must support the Offset Blocks in a series. Offset blocks are stacked in series with each one providing a maximum offset 2 5/8″. Offset direction may be left, right, back, or in a spiral pattern for “twisting” flues.
