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.
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 dete-
rioration 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.
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.
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.
NOTICE: Check with your local building authorities
and/or consult the National Fire Protection Association
(NFPA 211).

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 should be no more than  times the
cross-sectional area of the flue collar of the insert. (28 sq
inch flue area x  inches = 84 square inches maximum
chimney area).
• Should be lined with a 6 inch (152mm) stainless steel
flue liner to improve performance and reduce creosote
build-up.
• A n equivalent liner must be a listed chimney liner system
or other approved material.
