Masonry Chimney - Golden Eagle 7000 Owner's Installation And Operation Manual

MASONRY CHIMNEY :

Ensure that a masonry chimney meets the minimum standards of the National Fire Protection Association (NFPA) by having it
inspected by a professional. Make sure there are no cracks, loose mortar or other signs of deterioration and blockage. Have the
chimney cleaned before the furnace is installed and operated. When connecting the furnace through a combustible wall to a masonry
chimney, special methods are needed as explained in the "Combustible Wall Chimney Connector Pass-Throughs" Section.
