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 combustible
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)
Becauseof theextremeheat thisfireplace emits, themantel clearancesare
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.

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.
Eachdirectfluegasappliancemustuseit'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.
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 cor-
rect 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
corners).
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.)

The diagram below shows examples of horizontal termination arrangements using one, two, or three 90oelbows (two 45o elbows equal one 90o
elbow).
Note:
1) A maximum of three 90oelbows are permitted.
2) Minimum distance between elbows is 1 ft. (305mm).
• Maintain clearances to combustibles as listed on page 9.
• Horizontal flue must be supported every 3 feet.
• Firestops are required at each floor level and whenever passing through a wall.
• Must use optional flue adapter (Part# 510-994) when using Simpson Dura-Vent pipe.
• A vent guard should be used whenever the termination is lower than the specified minimum or as per local codes.

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
thewaywhentheflueingsystemisattached.
If this is the case, you may want to adjust
the location of the unit. Rough in the gas.
2) DirectFluepipeandfittingsaredesignedwith
specialtwist-lockconnectionstoconnectthe

twist-lock appliance adaptor is an available
option that must be used in conjunction
with the Simpson Dura-Vent Direct Vent GS
system.
3) Putabeadofsiliconeinsidetheoutersection
of the adapter and a bead of Mill Pac on the

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 fram-
ingusingnails or screwsthrough 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

onto the male ends of adjacent pipes
and fittings, by orienting the four pipe
indentations so they match and slide
in to the four entry slots on the male
ends,Diagram1.Pushthepipesections

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 terminated. If the wall being penetrated
isconstructedofnon-combustiblematerial,
i.e.masonryblockorconcrete,a7"(178mm)
dia. (7-1/2"(191mm) dia. for flex) hole is
acceptable.

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 standoff
or furring strips must be used to
ensure that the termination is not
recessed into the siding.
7) Beforeconnecting thehorizontalrunofflue
pipe to the flue termination, slide the Wall
Thimble (Part # 942) over the flue pipe.
b) Horizontal runs of flue must be sup-
ported every three feet. Wall straps are
available for this purpose.

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 fire-
stop.

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 combustibles of 1-1/4". Slip the flashing
underthe shingles(shingles shouldoverlap
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.

Note: If an offset is necessary in the attic
toavoid obstructions, itisimportant
to support the flue pipe every 3 feet,
to avoid excessive stress on the el-

Galvanized pipe is desirable above the roof-
line due to its higher corrosion resistance.
