Masonry Chimney
If using a masonry chimney, it must meet the minimum standards of the National Fire Protection Associa-
tion (NFPA) Standard 211. The chimney must have at least a 5/8" fi re clay liner or a listed chimney liner
system. The chimney must be inspected for cracks, loose mortar, or any other signs of deterioration. It
is best to have the chimney inspected by a professional. Make certain the chimney is cleaned prior to
installation of this fi replace.
The size of the chimney should be between 36 and 96 square inches. Larger chimneys should be re-
lined to meet these requirements. Incorrect sizing of the chimney may aff ect the draft and result in poor
fi replace performance. Do not install more than one appliance to any chimney.
There are diff erent accepted methods of connecting the fi replace to a masonry chimney through a com-
bustible wall. This type of installation requires the use of a thimble to protect the surrounding combustible
materials. Check with your local building offi cials or consult NFPA211.
