Chimney Systems
D. Masonry Chimney
• Must meet minimum standards of NFPA 211.
• Must have at least 5/8 inch (16mm) fireclay lining joined
with refractory cement. (Installations into a clay flue
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
(305mm) 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
flue 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 fireplace 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 fireplace.
3. 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 flue 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
specified below.
WARNING! Risk of Fire!
Follow venting manufacturer’s clearances and
instructions when installing venting system.
B. Inspections
Existing chimneys should be inspected and cleaned by a
qualified professional prior to installation. The chimney must
not have cracks, loose mortar or other signs of deterioration
and blockage. Hearth & Home recommends a NFI or CSIA
certified professional or a technician, under the direction of
a certified professional, conduct a Level II inspection per
NFPA 211.
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) UL103 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 flue can
affect draft and impair performance and will allow increased
build-up of creosote.
