Many people may wish to convert an existing
fireplace to heater use.
of stovepipe to a masonry chimney requires more
effort than connection to a prefabricated chimney.
Always remember to inspect the masonry chimney
and fireplace. If necessary, clean the flue and smoke
shelf before beginning your installation. Install the
heater into the fireplace so that the system can be
dismantled for cleaning and inspection.
Before deciding to convert your fireplace, keep
in mind that some fireplaces and existing chimneys
are unsafe. They must be structurally sound, and the
flue liner must be in good condition. Do not use a
chimney if it is unlined (should have a fire clay tile liner
to protect brickwork). Have it relined professionally.
Clearances to combustibles are explained in the
previous section on masonry chimneys. If you have
any questions regarding the condition of the chimney,
consult a qualified engineer, competent mason, or
knowledgeable inspector.
Many prefabricated fireplaces fall into the "zero-
clearance fireplace" category. This is a factory-built
metal fireplace with multi-layered construction.

CAUTION: Not all fireplaces are suitable for installation of a wood heater.
Venting Into A Fireplace
Usually, safe connection
cooling so that the base, back and sides can be safely
placed in direct contact with combustible floors and
walls. Although many prefabricated fireplaces have
been tested by nationally recognized organizations
for use as fireplaces, they have not been tested to
accept heaters. In fact, their use as such may void
the manufacturer's warranty.
Steel-lined fireplaces, on the other hand, can be used
with heaters. These units use a 1/4-inch firebox liner
and an air chamber in connection with 8 inches of
masonry to meet code. They contain all the essential
parts of a fireplace, firebox, throat, smoke shelf, and
smoke chamber. Many of them look exactly like a
masonry fireplace and must be checked closely for
above requirements before installing a wood heater
into them.
Another method frequently used by some people is
to vent the heater directly into the fireplace. This does
not meet code since the heater is being vented into
another appliance - the fireplace. This method should
not be attempted because combustion products will
deposit and build up in the firebox or fireplace. Be
It certain not to install a hazard in your house. You will
void your warranty with this installation.
