D. Masonry Chimney
• Must meet minimum standards of NFPA 11.
• 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 inches (10mm) nominal thickness.
•
A chimney of rubble stone must be at least 12 inches (305mm)
thick.
• Cross-sectional area should be no more than 3 times the
cross-sectional area of the flue collar of the insert. (8 sq inch
flue area x inches = 8 square inches maximum chimney
area).
• Should be lined with a 6 inch (15mm) 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
. 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 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 11.
Fire Risk
Inspection of Chimney:
•
Chimney must be in good condition.
• Meets minimum standard of NFPA 11
• Factory-built chimney must be 6 inch
(15mm) UL10 HT.
WARNING
NOTICE:
Check with your local building authorities
and/or consult the National Fire Protection Association
(NFPA 11).
C. Larger Chimneys
It is recommended that chimneys with larger diameters
than 6 inches (15mm) be relined. An oversized flue
can affect draft and impair performance and will allow
increased build-up of creosote.
