COMBUSTIBLE MANTELS
CLEARANCES
The clearances listed below are Minimum distances unless otherwise stated:
WARNING:
Fire hazard is an extreme risk
if these clearances (air space)
to combustible materials are
not adhered to. It is of greatest
importance that this fireplace
and flue system be installed
only in accordance with these
instructions.
Clearance to Combustibles from:
Back 0" (0mm)
Side 0" (0mm)
Floor 0" (0mm)
CAUTION REQUIREMENTS: The top, back and sides of the fireplace are defined by
standoffs. The metal ends of the standoffs may NOT be recessed into combus-
tible construction.
Determine the total thickness of the finished floor (eg. tile, carpet, slate) to allow
the finished surface to be flush with the base of the unit.
Ceiling Height from Floor 72" (1828mm)
Mantel Height from Base of Unit:
39" min. (991mm)
Horizontal Flue Clearances:
Top 64mm
Side 40mm
Bottom 40mm
Vertical Flue Clearances 40mm
Because of the extreme heat this fireplace emits, the mantel clearanc-
es are critical. Combustible mantel clearances from top of unit are shown in
Diagram to the right.
Note: A non-combustible mantel may be installed at a lower height if
the framing is made of metal studs covered with a non-
combustible board.
This drawing is to scale at 1:6 (one inch = 6 inches)
Mantel can be installed anywhere in shaded area or higher using this scale.
Caution: Ensure the paint that is used on the mantel and the facing is
"heat resistant" or the paint may discolour.
* If the 3" (76mm) metal extension trim is removed it must be replaced with a 8"
(203mm) non-combustible material.

FRAMING AND FINISHING
CAUTION: The unit does not have to be completely enclosed in
a chase. The clearance on top of the unit is 0" to the standoffs
so combustible building materials can be laid directly on top of
the standoffs. You must maintain clearance from the flue to
combustible materials for both rigid and flex, see Flue Clear-

FLUEING
INTRODUCTION
The P121/P121LC/P121RC/P131 uses the
"balanced flue" technology Co Axial system.
The inner liner flue products of combustion to
the outside while the outer liner draws outside
combustion air into the combustion chamber
therebyeliminatingtheneedtouseheatedroom
air for combustion and losing warm room air up
the chimney.
Note: These flue pipes must not be con-
nected to any other appliance.
The gas appliance and flue system must be
flueeddirectlyto theoutsideofthebuilding,and
never be attached to a chimney serving a
separate solid fuel or gas burning appliance.
Eachdirectfluegas appliancemustuseit'sown
separate flue system. Common flue systems
are prohibited.
INSTALLATION
UNIT ASSEMBLY
PRIOR TO
INSTALLATION
The 4 Top Standoffs must be correctly positioned and attached to the top before unit is slipped
into position.
TopStandoffAssembly
The top standoffs are shipped in a flat position and must be folded into shape and attached.
1) Remove the standoffs from the fireplace
top.
2) Take each standoff and bend into the
correct shape. Bend up at the bend lines
untilthe screwholesinthe standoffandthe
pre-punched screw holes on the fireplace
top line up.
3) Attach the standoff securely to the top with
4 screws per standoff (on opposite cor-
ners).
FACING & FINISHING REQUIREMENTS
This fireplace is supplied with a 3" (76mm) metal extension trim above the fireplace. The extension trim may be replaced if the framing is faced with
a non-combustible material placed flush with the front and side face of the unit and extending from the top of the unit. (ie. tile, slate, etc.)

HORIZONTAL
INSTALLATIONS
Install the flue system according to the
manufacturer's instructions included
with the components.
1) Set the unit in its desired location. Check to
determine if wall studs or roof rafters are
in the way when the flueing system is
attached. If this is the case, you may want
toadjustthelocationoftheunit.Roughinthe
gas.
2) Put a bead of silicone inside the outer
sectionoftheadapterandabeadofMillPac
ontheinnercollar.Sliptheadapterover the
existing inner and outer flue collar and
fasten to the outer collar only with the 3
supplied screws (drilling pilot holes will
make this easier). Level the fireplace and
fastenittotheframingusingnailsorscrews
through the nailing strips.
3) Assemble the desired combination of pipe
and elbows to the appliance.
Note: Apply sealant "Mill-Pac" to inner
pipe and high temperature sili-
cone sealant to outer pipe.
Horizontal runs of flue must be supported
every three feet. Wall straps are available
for this purpose.
4) Mark the wall for a 10" x 10" square hole.
Thecenterofthesquareholeshouldlineup
with the centerline of the horizontal pipe.
Cutandframethe10inchsquareholeinthe
exterior wall where the flue will be termi-
nated. If the wall being penetrated is con-
structed of non-combustible material, i.e.
masonry block or concrete, a 7"(178mm)
dia. (7-1/2"(191mm) dia. for flex) hole is
acceptable.
6) Before connecting the horizontal run of
flue pipe to the flue termination, slide the
Wall Thimble over the flue pipe.
7) Slide the appliance and flue assembly to-
wards the wall carefully inserting the flue
pipe into the flue cap assembly. It is impor-
tant that the flue pipe extends into the flue
cap sufficient distance so as to result in a
minimumpipeoverlapof1-1/4(32mm)inch-
es. Secure the connection between the
flue pipe and the flue cap by attaching the
two sheet metal strips extending from the
flue cap assembly into the outer wall of the
flue pipe. Use the two sheet metal screws
provided to connect the strips to the pipe
section. See Diagram 2.
8) Install wall thimble in the center of the 10"
square and attach with wood screws, see
Diagram3.
Note: If installing termination on a siding
covered wall, a vinyl siding stand-
off or furring strips must be used
to ensure that the termination is
not recessed into the siding.

Note:
a) Thehorizontalrunoffluemustbe
level, or have a 1/4 inch rise for
every 1 foot of run towards the
termination.Never allow the flue
to run downward. This could
cause high temperatures and
may present the possibility of a
fire.
b) Thelocationofthehorizontalfluetermi-
nation on an exterior wall must meet all
local and national building codes, and
must not be blocked or obstructed. For
External Flue Terminal Locations, see
diagram on page 12.
5) The arrow on the flue cap should be
pointing up. Insure that the 1-1/2"(40mm)
clearances to combustible materials are
maintained(Diagram1).Installthetermina-
tion cap.
The four wood screws provided should be
replaced with appropriate fasteners for
stucco, brick, concrete, or other types of
sidings.
With the above options, maximum total pipe length if 37 feet with
minimum of 5 feet total vertical and maximum 12 feet total horizontal.
Please note minimum 1 foot between 90oelbows is required.

Note: Apply sealant "Mill-Pac" to inner
pipe and high temperature silicone
sealant to outer pipe on every twist-
lock joint.
3) A Firestop spacer must be installed in the
floor or ceiling of every level. To install the
Firestop spacer in a flat ceiling or wall, cut
a 10 inch square hole. Frame the hole as
shown in Diagram 3 and install the firestop.
6) Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic
to avoid obstructions, it is impor-
tant to support the flue pipe every
3 feet, to avoid excessive stress
on the elbows, and possible sep-
aration. Wall straps are available
for this purpose (Diagram 2).
Galvanized pipe is desirable above the roof-
line due to its higher corrosion resistance.
Continue to add pipe sections through the
flashing until the height of the flue cap meets
theminimumheightrequirementsspecifiedin
Diagram5orlocal codes. Note that for steep
roof pitches, the vertical height must be in-
creased. A poor draft, or down drafting can
resultfromhighwindconditionsnearbigtrees
oradjoiningrooflines,inthesecases,increas-
ing the flue height may solve the problem.
7) Ensure flue is vertical and secure the base
of the flashing to the roof with roofing rails,
slide storm collar over the pipe section and
seal with a mastic.
8) Install the vertical termination cap.
Note: Any closets or storage spaces,
which the flue passes through
must be enclosed.
Diagram 4: The upper half of the flashing is
installed under the roofing material and not
nailed down until the chimney is installed.
This allows for small adjustments.
4) Assemble the desired lengths of pipe and
elbows.
5) Cut a hole in the roof centered on the small
drilled hole placed in the roof in Step 2. The
hole should be of sufficient size to meet the
minimumrequirementsforclearancetocom-
bustibles of 40mm. Slip the flashing under
the shingles (shingles should overlap half
theflashing)asper Diagram4.(Flashingnot
supplied).

mark the spot where the flue will penetrate
the roof. Determine if ceiling joists, roof
rafters or other framing will obstruct the
flueing system. You may wish to relocate
the appliance or to offset, as shown in
Diagram 2 to avoid cutting load bearing
members.

4) Separate the 2 halves of the wall thimble
and securely fasten the one with the tabs
totheoutsidewallmakingsurethatthetabs
are on top and bottom. Fasten the other
thimble half to the inside wall. The thimble
halves slip inside each other and can be
adjusted for 2 x 4 or 2 x 6 walls. The liners
must slip over the collars a minimum
of 1-3/8".
5) Slip the assembled liner and termination
assembly through the thimble making sure
the termination cap faces up (there are
markings on the cap that show which way
is up). This will position the termination cap
with proper down slope for draining water.
Fasten the cap to the outer wall with the 4
supplied screws.
6) Pull the centre 4"(100mm) liner and outer
6-7/8"(175mm)lineroutenoughtoslipover

8) Do the same with the 6-7/8"(175mm) liner.
9) Apply a bead of silicone between the thim-
ble and termination and around the outer
edge of the terminal at the wall in order to
keep the water out.
Note: To make the
installation more
aesthetically pleas-
ing, we recom-
mend framing out a
square to mount
the terminal to.
Note: If installing termination on a sid-
ing covered wall, furring strips
must be used to ensure that the
termination is not recessed into
the siding.
2) Level the fireplace and fasten it to the
framing using nails or screws through the
nailing strips.
3) Assemble the flue assembly by applying

termination and slipping the 4"(100mm)
liner over it at least 1-3/8" (35mm). Fasten
with the 3 screws (drilling pilot holes will
make this easier). Apply Mill Pac or high
temperature silicone to the 6-7/8"(175mm)
flex pipe and slip it over the 6-7/8" outer
collar of the flue terminal at least 1-3/
8"(35mm) and fasten with the 3 screws.
NOTE: Horizontal sections must be sup-
ported at intervals not exceeding
3 feet (0.9 meter). (Flame picture
and performance will be affected
by sags in the liner).

Flue System (Flex)
1) Locate the unit in the framing, rough in the
gas. Locate the centerline of the termina-
tion and mark wall accordingly. Cut a
10"(254mm) hole in the wall (inside dimen-
sion).
Note: A 1-1/2"(38mm) clearance around
the liner must be maintained ex-
cept that only a 1" (25mm) clear-
ance is needed at the termination
end. We recommend framing a
10"(254mm) x 10"(254mm) (inside
dimensions) hole to give struc-
tural rigidity for mounting the ter-
mination.
IMPORTANT: Do not locate termination
hood where excessive snow or ice build-
upmayoccur.Besuretocheckfluetermi-
nation area after snow falls, and clear to
prevent accidental blockage of flueing
system. When using snow blowers, make
sure snow is not directed towards flue
termination area.
