COMBUSTIBLE MANTELS
CLEARANCES
The clearances listed below are Minimum distances unless otherwise stated (refer to diagrams on page 8):
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 2-1/2"(64mm)
Side 1-1/2"(38mm)
Bottom 1-1/2"(38mm)
Vertical Flue Clearances 1-1/4" (32mm)
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-
ances, page 9.

See page 11 for assembly. Use 2x4's and frame to local building
codes.
2) When locating your appliance on an exterior wall or in a chase, apply
a vapour barrier and drywall, as per local building codes. DO NOT
INSULATE THE FIREPLACE ITSELF.
CAUTION: Verify your fireplace dimensions, framing methods
and finished wall facing details before framing. Determine the
total thickness of facing material - drywall plus ceramic tiles,
slate, etc. Allow the finish surface to be flush with the front or
side of the unit. Total facing thickness can vary from 1/2"
(13mm) to 1-1/4" (32mm) thick.

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
thereby eliminating the need to use heated room
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
flueed directly to the outside of the building, and
never be attached to a chimney serving a
separate solid fuel or gas burning appliance.
Each direct flue gas appliance must use it's
own separate flue system. Common flue sys-
tems 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.
Top Standoff Assembly
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
until the screw holes in the standoff and the
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" 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.)

INSTALLATION
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 at-
tached. If this is the case, you may want to
adjust the location of the unit. Rough in the
gas.
2) Direct Flue pipe and fittings are designed
with special twist-lock connections to con-
nect the flueing system to the appliance flue
outlet. A twist-lock appliance adaptor is an
available option that must be used in con-
junction with the Simpson Dura-Vent Direct
Vent GS system.
3) Put a bead of silicone inside the outer section
of the adapter and a bead of Mill Pac on the
inner collar. Slip the adapter over the exist-
ing 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 fasten it to
the framing using nails or screws through
the nailing strips.
4) Assemble the desired combination of pipe
and elbows to the appliance adaptor and
twist-lock for a solid connection.
Note:
a) Twist-lock procedure: Four indentations,
located on the female ends of pipes and
fittings, are designed to slide straight
onto the male ends of adjacent pipes and
fittings, by orienting the four pipe inden-
tations so they match and slide in to the
four entry slots on the male ends, Dia-
Diagram 1
b) Horizontal runs of flue must be sup-
ported every three feet. Wall straps are
available for this purpose.
5) Mark the wall for a 10" x 10" square hole.
The center of the square hole should line up
with the centerline of the horizontal pipe.
Cut and frame the 10 inch square hole in the
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.
Note: With Dura-Vent, the minimum height
is achieved by installing a 45
o
elbow di-
rectly to the flue adaptor.
Diagram 2
Note:
a) The horizontal run of flue must be 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) The location of the horizontal flue termi-
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.
6) The arrow on the flue cap should be
pointing up. Insure that the 1-1/2" clear-
ances to combustible materials are main-
tained (Diagram 3 on page 16). Install the
termination cap.
The four wood screws provided should be
replaced with appropriate fasteners for
stucco, brick, concrete, or other types of
sidings.
Note: If installing termination on a siding
covered wall, a vinyl siding stand-
off or furring strips must be used
Note: Apply sealant "Mill-Pac" to inner
pipe and high temperature sili-
cone sealant to outer pipe on eve-
ry twist-lock joint.

pletely together, then twist-lock one
section clockwise approximately one-
quarter turn, until the two sections are
fully locked. The female locking lugs will
not be visible from the outside, on the
Black Pipe or fittings. They may be
located by examining the inside of the
female ends.

VERTICAL
TERMINATION
1) Maintain the 1-1/4" clearances (air
spaces) to combustibles when
passing through ceilings, walls,
roofs, enclosures, attic rafter, or
other nearby combustible surfac-
es. Do not pack air spaces with
insulation. Check pages 17-19 for
the maximum vertical rise of the
flueing system and the maximum
horizontal offset limitations.
trate the ceiling. Drill a small hole at his point.
Next, drop a plumb bob from the roof to the
hole previously drilled in the ceiling, and
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 Dia-
gram 2 to avoid
cutting load
bearing mem-
bers.
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.
4) Assemble the desired lengths of pipe and
elbows. Ensure that all pipes and elbow
connections are in the fully twist-locked
position and sealed.
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
minimum requirements for clearance to com-
bustibles of 1-1/4". Slip the flashing under
the shingles (shingles should overlap half
the flashing) as per Diagram 4.

over 20/12 to 21/12 8 2.44
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.
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
the minimum height requirements specified in
Diagram 5 or local codes. Note that for steep
2) Set the gas appliance in
its desired location. Drop
a plumb bob down from
the ceiling to the position
of the appliance flue exit,
and mark the location
where the flue will pene-

to ensure that the termination is
not recessed into the siding.
7) Before connecting the horizontal run of flue
pipe to the flue termination, slide the Wall
Thimble (Part # 942) over the flue pipe.
8) 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
minimum pipe overlap of 1-1/4 inches. Se-
cure 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 4.
9) Install wall thimble in the center of the 10"
square and attach with wood screws (Di-
agram 5).
