The
fireplace
should
be
installed
on
a
solid
continuous
surface.
Do
not
install
your
fireplace
on
a
floor
covered
with
carpeting,
vinyl
or
similar
soft
combustible
material.
However,
the
fireplace
may
be
installed
directly
on
plywood,
particle
or
other
solid
combustible
material.
The
fireplace
may
be
located
practically
anywhere
in
the
room.
You
should
consider
ceiling
and
roof
rafters
that
may
require
cut
ting
and
plumbing
and
wiring
that
may
have
to
be
moved
when
deciding
where
to
locate
the
fireplace.
The
opening
of
the
fireplace
must
not
be
located
closer
than
24
inches
to
any
perpendicular
wall.

Three
additional
optional
items
that
must
be
considered
are;
1)
gas
appliance
accessories,
2)
outside
combustion
air
and
3)
electrical
connections
for
blower
assembly.
In
order
to
allow
for
easy
installation
of
any
of
these
items,
it will
be
necessary
for
you to
locate
the
fireplace
near
the
appropriate
utility
outlet.
Refer
to the
section
in
these
instructions
concerning
the
accessory
you
intend
to
use.
The
Chimney
System:
The Trueheat* Trueflow
double
wall
chimney
system
has
been
specially
designed
and
UL
Listed
for
use
with
all
Trueheat*
fireplaces.
The
Trueheat*
28
and
36
inch
models
employ
the
8
inch
Trueflow
chimney
while
the
42
inch
models
use
the
10
inch
Trueflow
chimney.
The
Trueheat"
Trueflow
chimneys
must
be
in
stalled
at
a
minimum
two
inch
clearance
or
"air
space"
from
com
bustible
material.
Combustible
material
is
defined
as
any
material
that
will
burn
such
as
wood,
paper,
plastics,
etc.
Trueflow
chimneys
may
be
installed
with
one
or
two
30°
off
sets
(pair of
elbows)
per
fireplace-chimney
system.
Offsets
may
be
desired
to
avoid
plumbing,
wiring,
roof
joists,
etc.
Never
use
more
than
two
30°
offsets
per
system
and
never
connect
2
or
3
elbows
together
to
make
a
60°
or
90°
offset.
Always
secure
the
4
elbow
support
straps
to
framing
members
of
the
structure.
The
maximum
offset
distance
is 8 ft. (To
achieve
an
8 ft.
offset
you
must
use
4 - 4 ft.
sections
of
pipe.
The
rise
for
an
8 ft.
offset
is
14Vi ft.)
See
FIG. 6.
Always
terminate
the
fireplace
chimney
to
the
exterior
of
the
structure.
All
chimneys
should
be
terminated
a
minimum
of
three
feet
above
the
point
closest
to
roof
of
the
structure
and
use
the
10 ft. rule.
See
FIG. 7.
The
3ft.
height
helps
create
the
proper
draft
in
the
chimney
system
and
is
necessary
to
keep
the
fireplace
system
safe.
The
minimum
height
of
the
fireplace
and
chimney
systems
are
given
in
Table
1.
Trueheats
Trueflow
8
and
10
inch
chimney
systems
may
employ
two
30°
offsets
also.

Next look on the Vertical Installation ChartTable 2 to determine the pieces of pipe required forthe desired height. A 23 ft. in
stallation requires5 sections of
F48-8
chimney pipe,as shown on Table 2,a fireplace and chimneycap. Ifyou were installing a
TH42 fireplace,
you
would
only
need
the
pipe required for a 22 ft. 6 inch installation
because
TH42 is 6
inches
taller
than
a
TH36 orTH28
so
you
subtract
6
inches
from
the
desired height. From
the
Vertical Installation Chart, a 22 ft. 6 in. installation re
quires
two
F12-8,
one
F18-8
and
four F48-8
chimney
sections.
EXAMPLE
B:
Let's say you are installing the fireplace in your family room. Directlyabove the place where you would like to in
stall
the
fireplace is a bedroom. Therefore you
want
to
offset
the
chimney
to avoid
the
room. Inorder
to
calculate
the
distance
required, measure from the center of
the
fireplace to the back edge of the obstruction. Add to that distance 9 in.
The
number
you
have
calculated
is
the
center-to-center
offset
desired.
SEE
EXAMPLE B FIG.
The
measurement
from
the
center
of
the
fireplace
chimney
opening
to
the
rear
of
the
house
is 12 in.
The
calculated
center-to-center
offset
would
be
21 in.
To
determine
the chimney
components
required to obtain a 21 in.
offset
refer to Table 3. FromTable 3 you can
see
the
closest
offset
TO21 is
21V*.
So the chimney sections required areone pairof 30°elbows (offsets), and one
F36-8
chimney section.The risedeveloped
over a 21% in.
offset
is 39 in. Therefore, to determine what other chimney
sections
are required to obtain
the
desired installed
height, you simply subtract 39 in. from the height desired and refer to Table 2 for the necessary chimney components.

OUTSIDE
AIR
AllTrueheat®
fireplaces
are
equipped
to
accept
outside
combus
tion air if
desired.
By
using
outside
combustion
air
you
will
increase
the
efficiency
of
the
fireplace
by
reducing
the
amount
of
room
air
that
will
be
used
for
combustion.
Therefore,
it
is
recommended
that
the
outside
air
system
be
used
whenever
practical.
The
outside
air
system
consists
of
one
house
vent,
one
section
of
flexhose,
two
plastic
ties,
and
one
starting
collar.
The
outside
air
flexhose
should
be
Installed
to
bring
outside
air
from
the
exterior
of
the
structure
to
the
fireplace.
The
house
vent
should
be
installed
on
the
exterior
of
the
structure
and
located
so
that
the
vent
will
not
be
blocked
by
snow,
leaves
or
other
debris.
The
house
vent
should
never
be
installed
to
take
air
from
an
attic
space,
garage,
or
any
other
area
that
may
contain
combustible
fumes.
See
Fig. 11
and
12
for
installation
of
outside
air
duct.
The
flex
air
duct
may
be
installed
in

BY
STEP
INSTALLATION:
Use the
step
by
step
instructions
as
aguide for installing your Trueheat®fireplace. It may be
necessary
to alter from the
exact
order
of
these
instructions
depending
on
your
particular
installation.
Step
1: Choose a Location for
the
fireplace. When
selecting
the
location
remember
to
take
into
consideration
the
nearest
available power
source,
outside
air
source
and
gas
source
if you intend to
use
any
of
the
optional
features
available. Also
check
the
ceiling
above
the
desired
location for furnace
ducts,
wiring or plumbing. SEE FIREPLACE
LOCATION
AND FIG. 1.
Step 2. Place the fireplace in the desired location. Ifyou are installing the fireplace in an existing structure, remove any
carpetingor other soft combustible coveringfromthe floorwherethe fireplace is to be installed. Ifthe fireplace is being installed
Page
12

on a combustible surface, install the metal safety strip underthe
front
edge of the fireplace as shown in
FIG.
9. If you desire
the
fireplace
on a
raised
hearth,
then make sure that the
fireplace
rests on a solid continuous
platform.
Ifthe
platform
is
on an exterior wall of the home then it should be insulated with insulation with the same R factor as the exterior walls of
the structure.
Level
the fireplace using shims if necessary. If the fireplace is not level it could move after installation.
Step
3. Now you are ready to
cut
the
holes
in
the
ceiling for
the
chimney.
Drop a
plumb
line
from
the
ceiling directly above
the
fireplace and
locate
the
point directly
above
the
flue
outlet
on
the
top
of
the
fireplace.
This
point
is
the
center
of
the
chimney.
Mark
this
point
and
measure
over
9
inches
in
each
direction.
The
18
inch
by
18
inch
square
formed is
the
opening
required
for
the
chimney.
For installation
of
the
TH42
use
91/2
inches
in
each
direction
and
a 19
by
19
hole.
See
FIG. 19.
This
same
procedure
should
be
followed
for
each
level
that
is
to
be
penetrated.
Step
4:
After
cutting
a
hole
in
the
last
ceiling,
you
are
now
ready
to
locate
and
cut
the
hole
in
the
roof
of
the
structure.
The
roof
hole
can
be
located
using
a
plumb
line
as
shown
in
Step
3.
However,
the
length
of
the
hole
through
the
roof
will
depend
on
the
pitch
of
the
roof
and
the
size
of
the
roof
joist
members.
Tables
5
and
6
give
the
various
roof
opening
sizes.
FIG.
20
shows
how
the
minimum
size
is
measured.
Step
5.
Framing
the
ceiling
and
roof
joist
openings
is
next.
Framing
is
necessary
to
maintain
the
structural
integrity
of
the
joist
area.Crossmembers
should
be
nailed

Step 6. Firestopspacers should nowbe installedat
every
joist
level
except the
roof.
Thefirestop spacers should be
nailed
upto the bottomof the joist between
living
spaces and nailed
down
to the top of the joist in the attic space. See
FIG.
22.
Please note that roofjoist shields must be installed
as
outlined on page 9 for the TH42series and all double offset installations.
Step
7:
You
are
now ready to install
the
fireplace
chimney system. Determine the numberof chimney
sections required to reach
the
desired height
and
install the shortest chimney section first to
the
top
of the fireplace. The reason for installing
the
shortest
sections
first is
so
there
are
fewer joints
of pipe above
the
roof. To install a
section
of pipe,
firmly
push the inner (stainless steel) pipe down in
to
the
8 or 10inch starting flue on
the
fireplace. The
pipe
must
lock
securely
into
position.
To
check
the
fit, pull up on pipe
section.
Ifproperly
installed
the
pipe will not pull
out
of
the
flue on
the
fireplace.
If
the
pipe
pulls
out
push
it
back
down
inside
the
pipe until it locks. Next, install
the
outer
pipe. Push
the
outer
pipe
down
over
the
starting
collar
on
the
fireplace. Again, pull up on
the
pipe
to
make
sure
it is properly locked. Install
the
remaining pipe in
the
same
wayalways inserting the flue (center) pipe
inside
the
previous
section
and
installing
the
outer
section
over
the
outside
of
the
previous
section.
Check
each
section
to
make
sure
it is properly
locked
to
the
previous
section.
To
ensure
that
the
pipedoes not-come apart, the.instalier, at his option, mayattach the outer walls of the chimney pipe with 2
sheet
metal screws.
Drill
two holes 180°apart using %drillbit less than 2inches longand screw
sections
together. WARNING: BE
VERY
CAREFUL,
WHEN
DRILLING
HOLES IN THE OUTER PIPE, NOTTO

WARNING:
ALWAYS
MAINTAIN A MINIMUM 2 INCH
"AIR
SPACE"
TO
COMBUSTIBLES.
Step
7A:
If
offsetsare
required
toclearan obstruction inthe
pathway
ofthe
chimney
orifelbowsare
required
ina
multifamily
dwelling,
use
Trueheat®
30°offsets. Firstdeterminethe offset required bythe method described in Offset Installations and
the Offset Tables. Install straight chimney
sections
to
the
desired height and then install
the
offset elbow. (The offset elbow
is the elbow without support straps).
You
will
notice that the elbow's inner and outer pipes are unitized (one piece) and that
only the outer pipe
will
lock into the previous section of pipe. Next install the required sections of straight chimney pipe to
get the desired offset distance and install the
return
elbow.
(Return
elbow
has foursupport straps). Securelynail each of
the foursupport straps undertension to framingmembersofthe structure.Offsets mayangle inanydirection,forward, backward
or
sideways.
WARNINGS: 1.) NEVER INSTALL TWO ELBOWS TOGETHERTO MAKE A 60s OFFSET.
2.) THE MAXIMUM
OFFSET
DISTANCE IS 8 FT.
3.) ONLY USE 2 PAIRS OF 30° ELBOWS PER SYSTEM.
4.) ALWAYS ATTACH ALL FOUR ELBOW SUPPORT STRAPS.
5.) ALWAYS
MAINTAIN
A
MINIMUM
2
INCH
"AIR SPACE" TO COMBUSTIBLES.
6.) ALWAYS SECURE OFFSET SECTIONS WITH A
MINIMUM
OF TWO SHEET
METAL
SCREWS.
It is
recommended
each
offset
elbow
and
straight
section
of pipe to
attach
securely
with two
sheet
metal
screws
to help
support
the
chimney offset. Once the
sections
are securely attached, drill two holes 180°
apart
with a % inch drill bit
that
is
less
than
2
inches
long.
Secure
with a
sheet
metal
screw
in
each
of
the
two
places.
For
easier
installation,
attach
elbows
to straight offset
sections
or
sections
of pipe on
the
floor. Securing
the
offset
sections
will help provide
better
alignment
of
chimney
sections
and
a
safe
installation.
See
FIG. 23.
Step
8: You
