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 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 of Chimney:
• Chimney must be in good condition.
• Meets minimum standard of NFPA 211
• Factory-built chimney must be 6 inch
(152mm) UL10 HT.
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.
NOTICE: Check with your local building authorities
and/or consult the National Fire Protection Association
(NFPA 211).
