MANUFACTURED CHIMNEY
REFER TO CHIMNEY AND CHIMNEY CONNEC-
TOR MAKER’S INSTRUCTIONS FOR INSTALLATION
AND USE.
Use only 6” diameter listed chimney UL 103 HT.
Chimney made to this listing is High Temperature rated
to 2100 degrees Fahrenheit. Use chimney from only one
manufacturer. Never mix brands. Carefully follow the
chimney manufacturer’s stated requirements and clear-
ances. Use the chimney manufacturer’s attic guards,
roof supports, flashing and fire stops when passing
through a ceiling. Use a listed thimble when passing
through a combustible wall. Do not use makeshift com-
promises during installation.
Never use a single-wall
connection pipe as a chimney!
When using a pre-existing chimney, have it’s condi-
tion and installation inspected before using. Make sure
that the chimney meets all of the UL rating requirements
listed above. Be aware that not all manufactured chim-
ney is of the UL 103 HT type.
NOTE: It is recommended that you contact a li-
censed heating and cooling contractor (consult your
local yellow pages) for chimney installation.
Manufactured chimney with the proper required UL
listing is available from most home centers, hardware
stores, and HVAC supply stores.
If you have access to the internet, you may wish
to view chimney manufacturers’ information on-line.

VENTING TO EXISTING FIREPLACE
In some instances, people desire to convert an ex-
isting fireplace for stove use. Usually, safe connection to
an existing masonry chimney requires more work than
using a prefabricated chimney. The existing fireplace
must be closed and sealed at the damper with high-
temperature caulk, ceramic wool, or furnace cement.
Prior to installation, clean and inspect the existing flue
and smoke shelf. Installation should be designed so
the system can be dismantled for periodic cleaning and
inspection. Before conversion, make sure the existing
chimney is structurally sound, the chimney incorporates
a flue liner and make sure it is in good condition. (A flue
liner consists of clay tile that protects the brickwork of
a chimney. If a chimney does not have a liner, or it is
damaged, have it relined by a professional.
DO NOT
USE a chimney that is unlined or damaged!) If you
have any question regarding the condition of the chim-
ney, consult a qualified licensed contractor, qualified
engineer, competent mason, certified Chimney Sweep,
or a knowledgable inspector. Consult your insurance
company if you cannot find a qualified expert.
CAUTION: Not all fireplace chimneys
are suitable for conversion to a wood
stove. Check with a qualified expert.
Many prefabricated fireplaces are of the “zero-
clearance fireplace” category. These consist of mul-
tilayered metal construction. They are designed with
Chimney Minimum Height Requirements:
(1) Overall Height – 11 ft./3.35m min.
(2) Height above roof – 3 ft./91cm
(3) Height above slope – 2 ft./61cm min. within
10 ft./3.05m
(4) Minimum rise before horiz. section – 24 in./61cm
NOTICE: If minimum chimney requirements are
not met, your stove will not operate properly.
