CONNECTOR MAKER’S INSTRUCTIONS
FOR INSTALLATION AND USE.
Use only a 6˝ diameter manufactured chimney sys-
tem listed to 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 clearances. 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 compromises during installation.
WARNING: DO NOT USE SINGLE WALL CON-
NECTOR PIPE AS A CHIMNEY - A HOUSE FIRE
COULD RESULT.
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 require-
ments listed above. Be aware that not all manufactured
chimney is of the UL 103 HT type.
NOTE: It is recommended that you contact a
licensed 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 knowledgeable inspector. Consult your insurance
company if you cannot find a qualified expert.
CAUTION: NOT ALL FIREPLACE CHIMNEYS
ARE SUITABLE FOR CONVERSION TO ACCOM-
MODATE CONNECTION TO A WOOD STOVE.
CHECK WITH A QUALIFIED EXPERT.
Many prefabricated fireplaces are of the “zero-
clearance fireplace” category. These consist of
multi layered metal construction. They are designed
with enough insulation and/or air cooling on the
base, back and sides so they can be safely in-
stalled in direct contact with combustible floors and
walls. Although many prefabricated fireplaces carry
