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 FIREPLACES
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 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 installed in direct con-
tact with combustible floors and walls. Although many
prefabricated fireplaces carry endorsements from na-
tionally recognized organizations for use as fireplaces,
they have not been tested for connection to wood stove
heaters. Connecting a stove to such a device will void
the manufacturer’s warranty.
Steel-lined fireplaces are constructed with
1/4” firebox liner, an air chamber in connection with 8”
of masonry. These can be safely used with wood burn-
ing stoves. They contain all the essential components
of a fireplace, firebox, damper, throat, smoke shelf,
and smoke chamber. Many look identical to masonry
fireplaces and should be checked carefully before con-
necting a stove to them.
Venting a stove directly into a fireplace does not
meet code and should not be attempted. (This consti-
tutes connection to another appliance - the fireplace.)
Combustion products will be deposited and build up in
the firebox or fireplace. The stove warranty will be void
with such an installation. Do not create a hazard in your
home by connecting in this manner.

FIREPLACE INSTALLATION
NOTE: DO NOT ATTEMPT TO ROUTE THE
CHIMNEY CONNECTOR PIPE THROUGH THE
THROAT OF THE FIREPLACE.
Directly connecting the stovepipe into the existing
masonry chimney (figure 14 “Type A” fireplace conver-
sion) of the fireplace is the only approved method of
installation. This is a complicated and involved process
and to insure safety should only by done by a qualified
installer.
1. An entry hole must be cut through the masonry and
tile liner with minimal damage to the liner. At least 8”
