There
are
two
reasons
why
the
chimney
in
the
house
at
right
will
cold
backdraft
when
it
is
cold
outside
and
there
is
no
fire
burning
in
the
fireplace.
First,
the
chimney
runs
up
the
outside
of
the
house,
so
the
air
in
it
is
colder
and
denser
than
the
warm
air
in
the
house.
And
second,
the
chimney
is
shorter
than
the
heated
space
of
the
house,
meaning
the
negative
pressure
low
in
the
house
will
pull
outside
air
down
the
chimney,
through
the
fireplace
and
into
the
room.
Even
the
finest
fireplace
will
not
work
well
when
connected
to
this
chimney.
8.5
Chimney
Installation
Notes
1.
If
possible,
install
an
interior
chimney
as
it
will
provide
better
performance.
In
areas
with
continuous
temperatures
below
‐
18
C
(0
F),
the
use
of
an
exterior
chimney
increases
the
likelihood
of
operating
problems
such
as
low
draft,
high
rate
of
creosoting,
and
poor
start
‐
up
characteristics.
Exterior
chimneys
are
also
prone
to
down
‐
drafting
and
flow
reversal.
Installations,
which
are
located
on
lower
floors
in
the
house,
such
as
in
a
basement,
in
combination
with
outside
chimney,
are
especially
prone
to
flow
reversal.
2.
The
FP14
Cartier
is
listed
only
with
chimney
systems
described
in
table
1.
3.
A
chimney
venting
a
fireplace
shall
not
vent
any
other
appliance.
4.
The
minimum
chimney
system
height
for
a
straight
installation
is
15
ft.
(4,6
m).
5.
All
chimney
installations
must
include
at
least
one
support.
Reducing
the
amount
of
chimney
weight
on
the
fireplace
will
help
avoid
the
noise
created
when
the
fireplace
expands.
This
can
be
achieved
by
having
the
chimney
supported
by
the
supports.
The
maximum
chimney
length
that
should
be
supported
by
the
fireplace
is
9
ft.
(2.75
m)
for
2"
Solid
Pack
Chimney
and
12
ft.
(3.7
m)
for
1"
Solid
Pack
Chimney.
6.
The
chimney
must
extend
at
least
3
ft.
(92
cm)
above
its
point
of
contact
with
the
roof
and
at
least
2
ft.
(61
cm)
higher
than
any
wall,
roof
or
building
within
10
ft.
(3.1
m)
of
it.
See
the
figures
on
point
11
bellow
to
determine
the
configuration
that
applies
to
your
roof
(flat
or
sloped
roof
and
the
distance
between
the
chimney
and
the
highest
point
of
the
roof
and/or
the
nearest
chimney).
7.
Deviations
should
be
avoided
whenever
possible,
especially
the
most
pronounced.
Each
deviation
adds
some
restriction
to
the
chimney
system
and
may
lead
to
draft
problems.
8.
If
the
chimney
extends
higher
than
5
ft.
(1.5
m)
above
its
point
of
contact
with
the
roof,
it
must
be
secured
using
a
roof
brace.
9.
A
rain
cap
must
be
installed
on
top
of
the
chimney.
Failure
to
install
a
rain
cap
may
cause
corrosion
problems.
