Chimney Systems
D. Masonry Chimney
• Must meet minimum standards of NFPA 211.
• Must have at least 5/8 inch (16mm) reclay lining joined
with refractory cement. (Installations into a clay ue
without a stainless steel liner may reduce draw which affects
performance, will cause the glass to darken and produce
excessive creosote).
• The masonry wall of the chimney, if brick or modular
block, must be a minimum of 4 inches (102mm) nominal
thickness.
• A chimney of rubble stone must be at least 12 inches
(05mm) thick.
• Cross-sectional area shall conform to NFPA 211-2006
Section 12.4.5.1.
• Should be lined with a 6 inch (152mm) stainless steel ue
liner to improve performance and reduce creosote build-
up.
• An equivalent liner must be a listed chimney liner system
or other approved material.
• No dilution air is allowed to enter the chimney.
1. Secure the replace damper in the open position. If this
cannot be accomplished, it will be necessary to remove
the damper
2. Seal damper area of chimney around chimney connector
with a high temperature sealant or seal insert against
the face of the replace.
. Both methods must be removable and replaceable for
cleaning and re-installation.
• When possible, install an airtight clean-out door to the rear
of the smoke shelf.
A. Venting Systems
Chimney Connector:
It is also known as ue pipe or stove pipe. It must be
6 inches (152mm) minimum diameter stainless steel
connector pipe.
Chimney:
The chimney can be new or existing, masonry or
prefabricated and must meet the following minimum
requirements as specied below.
WARNING! Risk of Fire!
B. Inspections
Existing chimneys should be inspected and cleaned by a
qualied professional prior to installation. The chimney
must not have cracks, loose mortar or other signs of dete-
rioration and blockage. Hearth & Home recommends a
NFI or CSIA certied professional or a technician, under
the direction of a certied professional, conduct a Level II

Fire Risk
Inspection of Chimney:
• Chimney must be in good condition.
• Meets minimum standard of NFPA 211
• Factory-built chimney must be 6 inch
(152mm) UL10 HT.
WARNING
NOTICE: Check with your local building authorities
and/or consult the National Fire Protection Association
(NFPA 211).
C. Larger Chimneys
It is recommended that chimneys with larger diameters
than 6 inches (152mm) be relined. An oversized ue
can affect draft and impair performance and will allow
increased build-up of creosote.
