Empire 18” Length 14” Diameter Vent Pipe
The Empire 18 inch chimney section (model number WB14V18) is part of Empire's 14 inch chimney system for the Blackburn 54 wood firebox built with the 14 inch chimney (model WB54FB0F). Empire's price list marks the 14 inch parts as the venting for the Blackburn 54 before its summer 2026 change; the current Blackburn 54 (WB5412FB0F) uses the 12 inch parts.
Once joined, it adds 18 inches of effective chimney height, as listed in the installation manual (joints overlap 1 1/4 inch, already counted in that figure).
