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 vent 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 Vent Clearances:
Top 2-1/2"(64mm)
Side 1-1/2"(38mm)
Bottom 1-1/2"(38mm)
Vertical Vent Clearances 1-1/4" (32mm)
Because of the extreme heat this fireplace emits, the mantel clear-
ances 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.

VENTING
INTRODUCTION
The P121-1/P121LC-1/P121RC-1/P131-1 uses
the "balanced flue" technology Co Axial
system. The inner liner vents products of com-
bustion to the outside while the outer liner
draws outside combustion air into the combus-
tionchambertherebyeliminatingtheneedtouse
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 vent system must be
venteddirectlytotheoutsideofthebuilding,and
never be attached to a chimney serving a
separate solid fuel or gas burning appliance.
Each direct vent gas appliance must use it's
own separate vent system. Common vent sys-
tems are prohibited.

HORIZONTAL
INSTALLATIONS
Install the vent 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 venting 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 Vent pipe and fittings are designed
with special twist-lock connections to con-
necttheventingsystemtotheapplianceflue
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) Putabeadofsiliconeinsidetheoutersection
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-lockprocedure:Fourindentations,
locatedon thefemaleendsofpipesand
fittings, are designed to slide straight
ontothemaleendsofadjacentpipesand

tations so they match and slide in to the
four entry slots on the male ends, Dia-
Diagram 1
b) Horizontal runs of vent must be sup-
portedevery three feet.Wall straps are
available for this purpose.
5) Mark the wall for a 10" x 10" square hole.
Thecenterofthesquareholeshouldlineup
with the centerline of the horizontal pipe.
Cutandframethe10inchsquareholeinthe
exterior wall where the vent 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 45oelbow di-
rectly to the flue adaptor.
Diagram 2
Note:
a) Thehorizontalrunofventmustbelevel,
or have a 1/4 inch rise for every 1 foot
of run towards the termination. Never
allow the vent to run downward. This
could cause high temperatures and
may present the possibility of a fire.
b) The location of the horizontal vent ter-
mination on an exterior wall must meet
alllocalandnationalbuildingcodes,and
mustnot be blocked or obstructed. For
External Vent Terminal Locations, see
diagram on page 12.
6) The arrow on the vent 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.

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
venting system and the maximum
horizontal offset limitations.
ceiling. Drill a small hole at his point. Next,
drop a plumb bob from the roof to the hole
previouslydrilledintheceiling,andmarkthe
spot where the vent will penetrate the roof.
Determine if ceiling joists, roof rafters or
other framing will obstruct
the venting system. You may
wishtorelocate

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
minimumrequirementsforclearancetocom-
bustibles of 1-1/4". Slip the flashing under
the shingles (shingles should overlap half
the flashing) as per Diagram 4.

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 vent 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.

to ensure that the termination is
not recessed into the siding.
7) Before connecting the horizontal run of
vent pipe to the vent termination, slide the
WallThimble(Part#942)overtheventpipe.
8) Slide the appliance and vent assembly to-
wards the wall carefully inserting the vent
pipeinto the vent cap assembly. It is impor-
tant that the vent pipe extends into the vent
cap sufficient distance so as to result in a
minimum pipe overlap of 1-1/4 inches. Se-
cure the connection between the vent pipe
andthe vent capby attaching the two sheet
metal strips extending from the vent cap
assembly into the outer wall of the vent
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).
