MASONRY
FIREPLACE
REQUIREMENTS
The
masonry
fireplace
must
meet
the
minimum
requirements
found
in
the
building
code
enforced
locally,
or
the
equivalent
for
a
safe
installation.
Contact
your
local
Building
Inspector
for
requirements
in
your
area.
An
inspection
of
the
fireplace
should
include
the
following:
1.
CONDITION
OF
THE
FIREPLACE
AND
CHIMNEY:
The
masonry
fireplace
and
chimney
should
be
inspected
prior
to
installation,
to
determine
that
they
are
free
from
cracks,
loose
mortar,
creosote
deposits,
blockage,
or
other
signs
of
deterioration.
If
evidence
of
deterioration
is
noted,
the
fireplace
or
chimney
should
be
upgraded
and/or
cleaned
prior
to
installation.
Masonry
or
steel,
including
the
damper
plate,
may
be
removed
from
the
smoke
shelf
and
adjacent
damper
frame
if
necessary
to
accommodate
the
insert’s
chimney
liner,
provided
that
their
removal
will
not
weaken
the
structure
of
the
fireplace
and
chimney,
and
will
not
reduce
protection
for
combustible
materials
to
less
than
that
required
by
the
building
code.

INSTALLATION
INTO
AN
EXISTING
FACTORY
‐
BUILT
ZERO
‐
CLEARANCE
FIREPLACE:
It
is
possible
to
install
a
wood
insert
into
an
existing
factory
‐
built
zero
‐
clearance
fireplace.
However,
there
currently
exists
no
UL
or
ULC
standard
specific
to
that
type
of
installation.
The
factory
‐
built
zero
clearance
fireplace
must
be
listed;
that
is,
safety
certified
by
an
accredited
certification
agency
such
as
UL/ULC,
Omni
or
Intertek).
It
must
be
suitable
for
use
with
solid
fuel
and
nothing
in
the
owner’s
manual
must
specifically
prohibit
the
installation
of
a
fireplace
insert.
When
in
doubt,
check
with
the
fireplace
manufacturer.
The
installation
of
the
zero
‐
clearance
fireplace
MUST
be
thoroughly
inspected
by
a
qualified
person
to
ensure
that
it
still
meets
the
manufacturer’s
specifications.
The
chimney
must
be
at
least
1"
(25
mm)
larger
in
diameter
than
the
stainless
steel
liner
that
will
run
from
the
insert
flue
collar
to
the
top
of
the
chimney
termination.
Never
remove
parts
intended
to
insulate
the
zero
‐
clearance
fireplace
from
combustible
material.
Only
readily
detachable
parts
that
are
easily
replaced,
such
as
damper
parts,
screens,
and
doors,
are
to
be
removed
from
the
fireplace.
These
parts
should
be
stored
and
available
for
reinstallation
if
the
insert
is
ever
removed.
Removal
of
any
parts
which
render
the
fireplace
unfit
for
use
with
solid
fuel
requires
the
fireplace
to
be
permanently
labeled
by
the
installer
as
being
no
longer
suitable
for
solid
fuel
until
the
removed
parts
are
replaced
and
the
fireplace
is
restored
to
its
original
certified
condition.
Also,
any
air
vents,
grilles,
or
louvers
that
allow
air
circulation
around
the
fireplace
must
not
be
removed
or
blocked.
