CLEARANCES
The clearances listed below are Minimum distances unless otherwise stated:
A major cause of chimney related fires is failure to maintain required clearances (air space) to combustible materials. It is of
the 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)
Minimum Clearance from Top of Front Facing:
Mantel min.8" (203mm)
Ceiling 39" (990mm) from top of front facing above louvers.
Side Wall: 6" (152mm)
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)
Alcove Clearances:
Max. Depth 36" (914mm)
Min. Width 60" (1524mm)
Min. Height 80" (2032mm)
Caution Requirements
The top, back and sides of the fireplace are defined by
standoffs. The metal ends of the standoff may NOT be
recessed into combustible construction.
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.

MANTELS
Because of the extreme heat this fireplace emits, the mantel clearances are critical. Combustible mantel clearances from louver are
shown in the diagram below.
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 using the above scale for units with the
Flush Front and with the optional Bay Front.
Note: Ensure the paint that is used on the
mantel and the facing is "heat re-
sistant" or the paint may discol-
our.
Maximum
1-1/2" projection at 3"

INSTALLATION
Note: 43" (1092mm) is the minimum height for flex termination
and Simpson Dura-Vent terminations.
Diagram 1
1) Determine the total thickness of facing material (eg. drywall plus
ceramic tiles) to allow the finished surface to be flush with the front
of the unit. Total facing thickness can vary from 1/2" (13mm) to
1-1/4" (32mm) thick.
2) Frame in the enclosure for the unit with framing material. The framed
opening for the assembled kit is 47-1/2" high x 48-1/2" wide x
26-1/4"deep (1207mm H x1232mmWx667mm D). SeeDiagram1.
3) For exterior walls, insulate the enclosure to the same degree as the
rest of the house, apply vapour barrier and drywall, as per local
installation codes. (Do not insulate the fireplace itself.)
4) The unit does not have to be completely enclosed in a chase. The
clearanceontopoftheunitfromthetopstandoffsis0"socombustible
building materials can be laid directly on top of the standoffs. You

page 7. Combustible materials can be laid against the side and back
standoffs and the stove base.
FRAMING & FINISHING
IMPORTANT
When installing the unit with any vertical venting off the top of the unit
as shown, the minimum framing depth changes accordingly.
The HeatWave Duct Kit has different
clearance and framing requirements,
check the HeatWave manual for details.

VENTING
INTRODUCTION
The P48 uses the "balanced flue" technology
CoAxialsystem.Theinner linerventsproducts
of combustion to the outside while the outer
liner draws outside combustion air into the
combustion chamber thereby eliminating the
needtouseheatedroomairforcombustionand
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
vented 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 vent gas appliance must use it's
own separate vent system. Common vent
systems are prohibited.
Screw Facing Material

A 1/2" / 13mm
B 7/8" / 22mm
C*1-1/4" / 32mm
"C" Screw Position:
For a facing material depth of 1-1/4"
(32mm), the top facing support must be
reversed.
UNIT ASSEMBLY
PRIOR TO
INSTALLATION
TheTopFacingSupport,theSideNailingStrips
and the 2 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 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
2 screws per standoff (on opposite cor-
ners).
Top Facing Support and
Side Nailing Strips
Determine the total thickness of facing material
(e.g. drywall plus ceramic tiles) to allow the
finished surface to be flush with the front of the
unit. Total facing thickness can vary from 1/2"
(13mm) to 1-1/4" (32mm) thick.
The Top Facing Support & Side Nailing Strips
canbemountedin3differentpositionsdepend-
ing on the thickness of the facing material.
*For "C" screw position the top facing support
is reversed.
1) Mount Top Facing Support using the 3
suppliedscrewsintothethreepre-punched
screw holes on the top front of the unit. Use
holepositionsA, B, or Cdepending on your
facing depth.
2) Use the same screw hole position for the
Side Nailing Strips as was used for the Top
Facing Support. Attach each side nailing
strip using 3 screws.

6) The arrow on the vent cap should be
pointing up. Insure that the 1-1/4"(32mm)
clearances to combustible materials are
maintained(Diagram5).Installthetermina-
tion cap.
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.
The four wood screws provided should be
replaced with appropriate fasteners for
stucco, brick, concrete, or other types of
sidings.
7) Before connecting the horizontal run of
vent pipe to the vent termination, slide the
Wall Thimble (Part # 1247) over the vent
pipe.
8) Slide the appliance and vent assembly to-
wards the wall carefully inserting the vent
pipeinto thevent capassembly. 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
(32mm). Secure the connection between
the vent pipe and the vent cap by 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 6.
INSTALLATION
HORIZONTAL
INSTALLATIONS
Install the vent system according to the manu-
facturer's instructions included with the com-
ponents.
1) Settheunitin its desired location. Checkto
determine if wall studs or roof rafters are
in the way when the venting system is
attached. If this is the case, you may want
to adjust the location of the unit. Rough in
the gas preferably on the right side of the
unit and the electrical (junction block is on
the left side) on the left.
2) Direct Vent pipe and fittings are designed
with special twist-lock connections to con-
nect the venting system to the appliance
flue outlet. A twist-lock appliance adaptor
is an available option that must be used in
conjunction with the Simpson Dura-Vent
Direct Vent GS system. Install the adaptor
after the unit is set in its desired location
otherwise the unit will not fit through the
36-5/8" (930mm) high frame opening.
3) Put a bead of silicone inside the outer
section of the adapter and a bead of Stove
Mate on the inner collar. Slip the adapter
over 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.
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 indenta-
tions, located on the female ends of
pipesandfittings,aredesignedto slide
straight 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. (Diagram 1) Push the pipe
sections completely together, then
twist-lock one section clockwise ap-
proximately one-quarter turn, until the
two sections are fully locked. The fe-
malelockinglugswillnotbevisiblefrom
theoutside,ontheBlackPipeorfittings.
Diagram 1
They may be located by examining the
inside of the female ends.
Note: Apply sealant "Mill-Pac" to inner
pipe and high temp silicone seal-
ant to outer pipe on every twist-
lock joint.
b) Horizontal runs of vent must be sup-
ported every 3 feet (0.9meter). Wall
straps are available for this purpose.
5) Mark the wall for a 11" x 11" (279mm x
279mm) square hole. The center of the
square hole should line up with the center-
lineofthehorizontalpipe.Cutandframethe
11inch (279mm)squareholeintheexterior
wall where the vent will be terminated.
If the wall being penetrated is constructed
of non-combustible material, i.e. masonry
block or concrete, a 8" (203mm) diameter
hole is acceptable.
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
must not be blocked or obstructed. For
External Vent Terminal Locations, see
diagram on page 11.

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 (0.9 meter), to avoid exces-
sive stress on the elbows, and
possible separation. 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
flashinguntilthe height of the ventcap meets
theminimumheightrequirementsspecifiedin
Diagram5orlocal codes. Note that for steep
roof pitches, the vertical height must be in-
creased.
Diagram 3
Note:
Apply sealant "Mill-Pac" to inner pipe and
high temp silicone sealant to outer pipe
on every twist-lock joint.
VERTICAL
TERMINATION
1) Maintain the 1-1/4"(32mm)
clearances (air spaces) to
combustibles when pass-
ing through ceilings, walls,
roofs, enclosures, attic raft-
er, or other nearby combusti-
ble surfaces. Do not pack air
spaces with insulation.
Check pages 16-17 for the
maximum vertical rise of the
venting system and the maxi-
mum horizontal offset limita-
tions.
2) Set the gas appliance in its
desiredlocation.Drop
a plumb bob down
from the ceiling to the
position of the appli-
ance flue exit, and
mark the location
where the vent will
penetratetheceiling.Drillasmallhole 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 vent will
penetratetheroof.Determineifceilingjoists,
roof rafters or other framing will
obstruct the venting system. You
may wish to relo-
cate the appliance
or to offset, as
shown in Diagram
2 to avoid cutting
loadbearingmem-
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 11 inch (279mm) 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.
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.
5) Cut a hole in the roof centered on the small
drilledhole placedin 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"(32mm). Slip the
flashingundertheshingles(shinglesshould
overlap half the flashing) as per Diagram 4.

A poor draft, or down drafting can result from
highwindconditions near big treesor adjoin-
ing roof lines, in these cases, increasing the
vent height may solve the problem.
7) Ensureventisverticalandsecurethebase
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 by twist-
locking it.
Note: Any closets or storage spaces,
which the vent passes through
must be enclosed.

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 5"(127mm) liner and outer
8"(203mm) liner out enough to slip over the
flue collars of the fireplace. (You may wish
to cut the liner shorter to make it more
workable.)Donotbendliner more than 90o.
7) ApplyMillPacoverthefireplaceinnercollar
and slip the 5"(127mm) liner down over it
and attach with 3 supplied screws.
8) Do the same with the 8"(203mm) 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.
INSTALLATION
PROCEDURES
for Regency Direct Vent
System (Flex)
1) Locate the unit in the framing, rough in the
gas (preferably on the right side of the unit)
and the electrical (Junction block is on the
left side) on the left. Locate the centerline
ofthe terminationandmarkwallaccording-
ly.Cuta11"(279mm)holeinthewall(inside
dimension).
Note: A top clearance of 2-1/2"(64mm)
and side & bottom clearance of
1-1/2"(38mm) must be maintained
except that only a 1" (25mm) clear-
ance is needed at the termination
end. We recommend framing a
11"(279mm) x 11"(279mm) (inside
dimensions) hole to give struc-
tural rigidity for mounting the ter-
mination.
Note: If installing termination on a siding
covered wall, furring strips must
be used to ensure that the termi-
nation 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 vent assembly by applying
Mill Pac to the 5"(27mm) inner collar of the
terminationand slippingthe 5"(27mm) 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 temper-
aturesiliconetothe8"(203mm)flexpipeand
slip it over the 8" outer collar of the vent
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).
IMPORTANT: Do not locate termination
hood where excessive snow or ice build-
up may occur. Be sure to check vent
terminationareaaftersnowfalls,andclear
to prevent accidental blockage of venting
system. When using snow blowers, make
sure snow is not directed towards vent
termination area.
