MASONRY
FIREPLACE
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
FLUE
SYSTEM:
The
masonry
fireplace
and
flue
system
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
flue
system
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
wood
inbuilt’s
flue
liner,
provided
that
their
removal
will
not
weaken
the
structure
of
the
fireplace
and
flue
system,
and
will
not
reduce
protection
for
combustible
materials
to
less
than
that
required
by
the
building
code.
2.
FLUE
SYSTEM
CAPS:
Mesh
type
flue
system
caps
must
have
provision
for
regular
cleaning,
or
the
mesh
should
be
removed
to
eliminate
the
potential
of
plugging.
3.
ADJACENT
COMBUSTIBLES:
The
fireplace
should
be
inspected
to
make
sure
that
there
is
adequate
clearance
to
combustibles,
both
exposed
combustibles
to
the
top,
side,
and
front
as
well
as
concealed
combustibles,
in
the
flue
system
and
mantle
area.
Your
local
inspector
should
have
information
on
whether
older
fireplaces
are
of
adequate
construction.

INSTALLATION

‐
CLEARANCE
FIREPLACE:
A
‘built
‐
in’
appliance
is
designed
to
be
in
contact
with
or
built
into
a
heat
sensitive
structure
within
a
building.
These
types
of
appliances
must
be
tested
in
a
laboratory
in
accordance
with
AS/NZS
2918
to
ensure
their
compliance
with
safety
requirements.
There
is
no
such
thing
as
a
‘standard’
(untested)
built
‐
in
appliance.
As
each
model
or
appliance
may
have
markedly
different
installation
clearances
and
instructions,
it
is
extremely
important
to
follow
the
manufacturer’s
installation
instructions,
which
are
based
on
the
laboratory
tests
results.
The
Matrix
inbuilt
can
only
be
installed
with
the
Osburn
Matrix
zero
‐
clearance
kit
(sold
separately).
See
installation
instructions
provided
with
the
kit.
