A. Venting Systems
Chimney Connector:
It is also known as fl 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 specifi ed 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
qualifi ed 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 certifi ed professional or a technician, under
the direction of a certifi ed professional, conduct a Level II
inspection per NFPA 211.
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 fl ue
can affect draft and impair performance and will allow
increased build-up of creosote.
