I. Masonry Chimney
• Must meet minimum standards of
NFPA 211
.
• Must have at least 5/8 inch (16mm) fire clay 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.
This insert conforms with the
UL 1482 and ULC S628
(Canada)
in all respects, and is approved to
UL &
ULC safety standards
for installation and use within
a fireplace with a masonry chimney in accordance with
NFPA 211 and CAN/CSA-B365-01
.
NOTE:
In Canada, this fireplace insert must be installed
with a continuous chimney liner of a 6 inch (152mm)
diameter extending from the fireplace insert to the top of
the chimney.
The chimney liner must conform to the
Class 3 requirements of CAN/ULC-S635, Standard for
Lining Systems for Existing Masonry or Factory-Built
Chimneys and Vents, or CAN/ULC-S640, Standard for
Lining Systems for New Masonry Chimneys.

H. 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)
.
• 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.
a. Secure the fireplace damper in the open position. If
this cannot be accomplished, it will be necessary to
remove the damper
b. Seal damper area of chimney around chimney
connector with a high temperature sealant or seal
insert against the face of the fireplace.
c. 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.
