SAFETY FIRST
DO'S AND DONT'S
If this fireplace is not properly installed, a house fire could result. For your safety, follow the installation
directions. Contact your local authority having jurisdiction (such as municipal building department, fire
department, fire prevention bureau, etc.) regarding restrictions and installation requirements, and the need
to obtain a permit.
To ANYONE using this fireplace: these DO's and DONT's are for your safety.
1. DO read this instruction manual before lighting your first fire.
2. DO burn seasoned wood fuel or densified fuel logs or a combination of densified fuel logs and wood fuel.
3. DO operate the fireplace with the door fully closed. If the door is left partly open, gas and flame can be
drawn out of the fireplace opening, creating both fire and smoke hazards.
4. DO keep all combustible materials (furniture, firewood, etc.) at least 4' away from the front of the fireplace.
5. This fireplace needs periodic inspection and repair for proper operation. DO learn to properly use it and maintain
it.
6. DO have at least one smoke detector on each level of the house and at least one carbon monoxide detector.
7. To avoid glass breakage, DO NOT slam the fireplace door.
8. DO NOT ever use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid or similar liquids to start
or freshen up a fire in this fireplace. Keep all such liquids well away from the fireplace while it is in use.
9. DO NOT overfire the fireplace. If you are unable to slow down the burn rate of the fire or if the chimney connector
behind the top louver glows red, you are overfiring the fireplace.
10. DO NOT use a fireplace grate or other products not specified for use with this fireplace.
11. The burn rates are set by the manual air control at the factory. DO NOT tamper with the air control. DO NOT
install a flue damper that would allow you to reduce the chimney draft and thus slow the minimum burn rate.
12. To avoid damaging the fireplace, DO NOT operate it in a manner inconsistent with the operating instructions in
this manual.
13. DO NOT install an insert in this fireplace.

NOTE: We strongly recommend that our products be installed and serviced
by professionals who are certified by the National Fireplace Institute in the
U.S. or by Wood Energy Technology Transfer Inc. in Canada.
CREOSOTE: FORMATION AND REMOVAL
When wood is burned slowly, it produces tar and other organic vapors which combine with the expelled moisture
from the wood to form creosote. The creosote vapors can condense in the relatively cool chimney of a slow burning
fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely
hot fire.
The chimney should be inspected periodically during the heating season to see if a creosote build-up has occurred.
The presence in a chimney of soot or creosote in excess of 1/8" (3mm) thick will indicate the need for immediate
cleaning, possible modification of burning procedures, and more frequent inspections.
WARNING: BURN DRY WOOD ONLY.
DO NOT BURN: DRIFTWOOD, TREATED WOOD, COAL, GARBAGE, OR PLASTIC
Do not use construction scraps (e.g. 2x4 or plywood scraps) as your only supply of fuel as you can overheat and
seriously damage the fireplace. See Fuel section for more details.

PEARL 3600 Owner's Manual 4 RSF Woodburning Fireplaces
GENERAL SPECIFICATIONS
The PEARL3600 is environmentally friendly and meets the 2020 United States Environmental Protection Agency
(EPA) particulate emission standard with cordwood at an average emission rate of 1.5 grams per hour.
It also has an optimal efficiency of 79%. This has been established using the high heating value of the wood, under
the best burning conditions and using CSA B415.1-10 calculations.
Furthermore, the weighted average EPA efficiency is 74%. The later has been established using the higher heating
value of the wood, while burning EPA cordwood and using CSA B415.1-10 calculations.
It has been shown to deliver heat ranging from 13 000 to 50 000 BTU/h with an average of 25 000BTU/h. Please
refer to the "Improving efficiency”, the “Importance of draft”, the “Brun Time vs. Heat Output” and “Fuel” sections to
better understand the various factors that influence the efficiency and heat output of your fireplace.
OPTIONS
Internal Blower (FO-FDHB8): For increased air circulation and marginally more heat output, you can add an
optional fan.
Gravity Vents (FO-V2, FO-VGC or FO-V3):If you have any rooms directly above or adjacent to the room with the
fireplace that you would like to heat, you may want to consider the Gravity Vent Kits. The gravity vent uses ducts
and vents to distributes hot air to these rooms without the need for a blower.
Each gravity vent kit includes 5’ of insulated flexible ducting, a gravity vent starter, an outlet grill adapter, and a
decorative outlet grill. The different grill designs are shown below:
FO-V2
FO-VGC (grill only for FO-V2)
FO-V3
Heat Dump (FO-HD):For a simple way to pull heat away from the fireplace to another room or to the basement,
we offer the Heat Dump Kit. It includes a 180 cfm blower and is most often used to prevent the room with the
fireplace from overheating and provide supplemental heating to the basement when the fireplace is on the main
floor.
Gasket Replacement Kit (FO-GRK9): Over time, the door seal will develop wear and eventually needs to be
replaced when air leaks into the firebox. If you notice difficulty slowing down the rate of burn or shortened burn
times, it may be a good time to replace your door gasket.
NOTE: Some options require wiring and/or electricity for their installation. If there is any chance that any of these
options will be installed in the future then suitable wiring should be run during framing. Otherwise, it will be difficult
to install these options later. You can refer to page 28 for a list of options that require electricity.
Detailed installation instructions are included in the box with each option. These can also be obtained from our
Internet Web Site: www.icc-rsf.com.
WARNING: This fireplace has not been tested with a gas log set (unvented or vented). To reduce risk of fire or
injury, do not install a gas log set (unvented or vented) into this fireplace. Do not install a gas log lighter because
the heat produced by the fireplace will permanently damage the gas log lighter.

INSTALLATION
GENERAL INSTALLATION
Check with your local authority having jurisdiction (such as municipal building department, fire department, fire
prevention bureau, etc.) regarding restrictions and installation requirements, and the need to obtain a permit.
NOTE: We recommend that you remove the door until after all finishing work is completed around the fireplace.
This will reduce the possibility of scratches, vandalism, or damage to the finish caused by drywall dust, muriatic
acid, plaster, cement, paint or any other harmful spray or liquid.

PEARL 3600 Owner's Manual 8 RSF Woodburning Fireplaces
LOCATION
We recommend that you take the time to plan your entire installation (fireplace, chimney, and options) before
beginning the actual installation (refer to Figure 3). Your PEARL3600 fireplace may be installed in many different
ways (see Figure 4) without any special floor reinforcement.
Dimensions of the fireplace along with clearances are shown in Figure 1 and Table 1.
WARNING: If this fireplace is not properly installed, a house fire can result. For your safety, follow the installation
instructions and clearances. Do not pack required air space with insulation or other materials.
1. Note the location of roof and floor joists. Try to choose a location that does not require cutting them.
2. Do not build recessed shelves or cupboards in the enclosure above the fireplace. This must be kept as air
space.
3. If at all possible, run the chimney up through the inside of the house. If it must be run outside, it should be
enclosed in an insulated enclosure (see Installation: Chase Enclosure). Remember, a cold chimney causes
poor draft.
FRAMING
Walls on all interior sides of the fireplace enclosure should be finished and flat. Insulation or other materials should
not be placed in required clearance spaces around the fireplace. Because of the high heat output potential of the
PEARL3600, combustible materials must NOT go closer to the fireplace than the standoffs, top, back and sides.
The framing dimensions are larger
than required for ease of installation.
The Heat Dump Option will require at
least12" additional space on the
selected side. Ensure adequate
space is planned.

PEARL 3600 Owner's Manual 9 RSF Woodburning Fireplaces
CEILING CLEARANCE
Ceiling clearance is the distance from the bottom of the bottom standoffs (legs) of the fireplace to the ceiling. Under
no circumstances should the distance between the ceiling firestop and the base fireplace be less than the dimension
specified in Table 1 (C). The minimum ceiling clearance applies both to the room in which the fireplce is installed,
and the enclosure in which it is framed.
SECURING THE FIREPLACE IN PLACE
Once the fireplace is in its final location, take the time to attach it to the floor. Using at least two of the five small
brackets that were securing the fireplace to the crate, attach the casing of the fireplace to the floor. If possible, try
to have at least one, if not two, of the brackets screwed into the floor joists with 2" wood screws.
TOP STANDOFF INSTALLATION
The Top Standoff provides clearance to combustible framing and includes a heat shield as part of its design. The
Top Standoff MUST be installed to avoid fire and ensure a safe installation.
Screw the Top Standoff to the top of the unit in the location shown using the screws provided.
For shipping, the top standoff is flat. During installation, the back shield must be bent along the crease to a 45°
angle. When placing 2x4 framing along the Top Standoff, ensure an air gap of at least ¼” from framing to the back
shield. DO NOT fill the gap between the fireplace and the standoff with insulation or any other material; it will be
covered with the finishing material.
NOTHING CAN BE PLACED BELOW THE HEADER SUPPORTS OF THE TOP STANDOFF WHETHER
COMBUSTIBLE OR NOT. THE SPACE MUST REMAIN EMPTY.

OUTSIDE AIR DUCT
The use of outside air is not required unless specified
by local building codes. The Pearl 3600 includes a
rotating elbow that connects to the bottom of the unit
and can exit in any direction.
Use an insulated aluminium flexible duct rated at over
200° F. The duct should not exceed 12' vertical rise
above the base of the unit. We suggest using the 4"
RSF outside air kit (FO-INT).
To avoid condensation, it is recommended to use an
insulated duct long enough to include a «P-Trap»
loop.
The air inlet should always be at least 5’ lower than
the chimney rain cap and must never terminate in
attic spaces.
A 4" diameter duct can be used if the total duct run is
less than 25'. For longer runs, use 5" diameter duct.
For a 5" run, you will need to start at the fireplace in 4"
just to get from under the base and then use an
increaser from 4" to 5" to be able to continue in 5".
1. Use a short Phillips screwdriver to remove the
outside air cover located on the bottom of the fireplace, four screws hold it in place.
2. Bend the central part of the cover back and forth to break away the two tabs and remove the central part.
3. Attach the 4" aluminium duct to the inlet of the outside air elbow with metal screws.
4. If the insulated flexible duct has a plastic covering, remove this plastic cover over the flexible duct so that there
is no plastic cover on the duct under the fireplace and for at least 3" away from the fireplace. The plastic cover
MUST NOT get within 3" of the fireplace.
5. Tape the insulation to the aluminum ducting where the plastic cover was pulled back. Using aluminium tape to
hold it in place.
6. If using 5" flexible duct for the rest of the duct run, cut the 4" insulated flexible duct long enough to clear the
fireplace. Completely remove the plastic cover over the 4" duct. Pull back the insulation on the extremity of the
4" duct and attach it to the 4"-5" increaser with metal screws. Pull back the plastic cover and the insulation from
one extremity of the 5" duct. Attach that extremity of the 5" aluminium duct to the 4"-5" increaser with metal
screws. Replace the insulation and plastic over the 4" and 5" insulated flexible duct and tape it in place with
aluminium duct tape. Remember, the plastic cover MUST NOT get within 3" of the fireplace.
Figure 7 Outside Air Cover
7. Insert the outside air elbow into the support and install this assembly onto the fireplace, using at least two of
the screws that were removed previously but do not tighten it yet.

8. Orient the outside air elbow in the direction you want the outside air duct to go and tighten the screws.
9. Make a 4 ¼" (5 ¼" if using a 5" diameter duct) hole in the outside wall of the house. Push the outside air inlet
in from the outside. Seal the joint between the air inlet and the outside wall with an appropriate sealant.
10. Place the insulated flexible duct over the round sleeve on the outside air inlet. Carefully pull back the insulation
and plastic cover, exposing the flexible duct. Attach the duct with metal screws to the air inlet. Replace the
insulation and cover back over the duct. Tape the plastic cover in place with aluminium duct tape.
CAUTION: WHEN RUNNING THE DUCT AROUND CORNERS, BE SURE TO PREVENT CRIMPING THE
DUCT IN A WAY THAT WOULD RESTRICT THE COMBUSTION AIRFLOW.
FINISHING AROUND THE FIREPLACE
The decorative faceplate of the PEARL3600 fireplace is not meant to be covered, it is meant to be admired. DO
NOT cover the decorative faceplate of the fireplace or any of its louvers.
The decorative faceplate of the PEARL3600 extends ½" beyond the sides of the fireplace to be able to hide the
edge of the finishing material behind it. The decorative faceplate sits 1" proud of the top of the fireplace casing to
allow thin finishing materials to slip behind the rounded top of the decorative faceplate.
Before you begin, remove the decorative faceplate and bottom louver
to prevent damaging them while installing the finishing materials. To
remove the faceplate, use a 5/32 Allen key and remove the two screws
located on either side of the faceplate’s keystone centerpiece (see
Figure 8) Once the bolts are removed, the faceplate will be loose, so
with one hand holding the faceplate in place, close the door. Take a
good grip on both side of the faceplate and lift it up. There are two
brackets, one on each lower side, that need to be disengaged from the
base of the fireplace. Do not lose the hardware that secures the
faceplate to the fireplace.
To remove the bottom louver, simply open the door, grab the top of the
louver close to each extremity and pull forward. There are two high
temperature magnets, one on each side, close to the top of the louver
keeping it in place along with two supports close to the bottom of the
louver to support the weight of the louver.
If desired, you can also remove the glass door by lifting it off its hinges
Facing Requirements
Finishing materials that cover the facing of the fireplace MUST BE NON-COMBUSTIBLE (e.g. brick, slate, ceramic
tile, etc.). Drywall cannot get closer to the fireplace than the side and top standoffs. The front face of the top standoff
is considered part of the fireplace facing. The minimum size of a non-combustible facing is shown in Figure 9.
The non-combustible finishing materials may be installed so that they fit behind the decorative faceplate. Plan the
finishing of the fireplace in advance and plan for the material thickness including the adhesive coat. If you are using
a thin material (such as tile) and plan to install your finishing behind the decorative faceplate, you MUST be able to
reinstall the decorative facing properly or it may become a safety hazard.
NOTE: There is only 1” between the decorative faceplate and the fireplace body. For example, this is sufficient
for a ½” cement board, a ⅛” adhesive coat, and a ⅜” tile.
You can also finish your PEARL3600 with materials that will result in a combined thickness greater than 1" (e.g.
brick, stone, etc.). These materials will not fit behind the decorative faceplate and will protrude past the faceplate
once installed. If you are using thick finishing materials, then the decorative faceplate of the PEARL3600 can
be used as a template.
WARNING Gypsum boards or any other combustible material cannot touch the casing of the fireplace. Only non-
combustible material such as cement board can touch the fireplace casing.

PEARL 3600 Owner's Manual 13 RSF Woodburning Fireplaces
MANTEL
Masonry and other non-combustible mantels (shelf and posts) can be
placed anywhere around the fireplace facing. If the non-combustible
mantel is located between the top of the fireplace facing and the
specified height for a combustible mantel, then the wall portion between
the top of the fireplace facing and the mantel must be covered in non-
combustible material. If the non-combustible mantel is located at the
same height allowed for a combustible mantel, or higher, then no special
wall covering is required below the mantel.
If the combustible mantel shelf has a cross-section with variable depth,
it has to be installed so that its widest part is not installed lower than the
corresponding minimum installation height while making sure that the
lowest point of the mantel is not installed lower the minimum installation
height corresponding to itsdepth (Table 2). Mantel depth is always
measured from the face of the fireplace (see Figure 11). This is
regardless of the depth of materials used for finishing the facing.
Vertical mantel posts are permitted on either the side of the fireplace
facing. If they made from combustible materials, the mantel posts require
the clearances specified in Table 3.

CHIMNEY
This fireplace is certified for use with 6" ICC Model EXCEL chimney only. Please refer to Table 1 (D-E) for the
minimum and maximum chimney heights permitted with the PEARL3600 fireplace.
We recommend that the minimum height be increased by approximately 6" for every 1000' elevation above sea
level. Every 15°, 30° or 45° offset (one pair of elbows) also increases the minimum height. See Table 4 for more
precise recommended flue heights.
For example, if you are living 6015' above sea level, your chimney should terminate at least 15' from the top of the
fireplace if it is a straight chimney or at least 18'6" if one 30° offset is used as shown in Table 4.

Flue height is measured from the top of the fireplace to the top of the chimney before installing the rain cap.
If you have two different offsets (two pairs of different elbows), simply use the column for two offsets of the
biggest pair of elbows at your elevation to get your Minimum Flue Height.
CHIMNEY INSTALLATION
Make sure to read the EXCEL Chimney installation manual concerning requirements for supports, bracing,
anchors, etc. Refer to Table 1 (F) for the maximum chimney height that can be supported by the top of the fireplace.
WARNING: The clearance between the chimney and combustible material must be 2" or more. Do not fill this
area with insulation.
1. Cut and frame the required holes in the floor(s), ceiling(s) and roof where the chimney will pass through. The
rough opening in the framing is 12" square (the opening can be slightly bigger, but NEVER smaller).
2. From below, install a radiation shield in each floor through which the chimney passes. At the attic level, install
a radiation shield and a storm collar as shown in Figure 12.
WARNING: A radiation shield must be installed at each floor where the chimney passes through.
3. Place the first length of chimney on the fireplace. Secure the chimney length to the fireplace with the three
screws provided. Assemble the rest of the chimney.

PEARL 3600 Owner's Manual 15 RSF Woodburning Fireplaces
The chimney must extend at least 3' above its
point of contact with the roof and at least 2' higher
than any wall, roof, or building within 10' of it. If
the chimney is higher than 5' above the roof, it
must be secured using a roof brace.
4. At the roof, install a roof radiation shield (XM-
7ERRS). The roof radiation shield must be
installed so it extends 3" above the roof line.
5. Put the roof flashing into place.
•If the chimney is enclosed to the roof: use
a vented flashing .
•If the chimney is not enclosed to the roof:
use a regular flashing.
WARNING: Do not block any of the openings in
the vented flashing with sealant, caulking or any
other materials.
6. Place the storm collar over the chimney and
flashing. Place a bead of exterior sealant around
the chimney below the storm collar, pull the storm
collar through the sealant and seal it once again
on the top with the exterior sealant (DO NOT use
roofing tar).
7. Fit the rain cap on the chimney. Secure it tightly
in place.
OFFSET CHIMNEY
An elbow may be installed directly on top of the fireplace if required. See the detailed offset charts in the EXCEL
chimney installation manual. Use the offset option if you need to clear a joist or pass around a cupboard. See Figure
13 and Figure 14 for examples.
•Maximum offset angle:
•In USA: 30°;
•In Canada: 45°.
•Maximum number of elbows: four, resulting in two offsets and returns.
Install the fireplace and chimney as described earlier. When you require an elbow, proceed as follows:
1. Install the required elbow. Turn it in the desired direction, and fasten it to the chimney length with the three
metal screws provided at the joints.
2. Install enough lengths to obtain the desired offset. Secure each joint with three metal screws. Refer to the offset
charts provided with the EXCEL chimney installation manual for exact offset dimensions.
If the chimney goes through an outside wall as shown in Figure 14 and is enclosed on the other side of the wall,
then the outside plate of the angled wall radiation shield MUST NOT be installed.
3. Use another elbow to return the chimney to the vertical direction.
4. Install a roof support, a wall support, or an offset support above each offset to support the weight of the chimney
(elbows are not designed to support the chimney above an offset).
Through the Wall Offset
You can also go through the wall at an angle starting directly at the fireplace as depicted in Figure 14. An angled
wall insulated radiation shield (XM-6EWRSI30 or XM-6EWRSI45) must be used wherever the chimney passes
through a combustible exterior wall. Make sure you have enough ceiling height. If not, you might want to consider
installing the fireplace in an outside chase.

If the chimney is enclosed once outside of the house, do not install the outside plate of the angled wall insulated
radiation shield.
Refer to the angled wall insulated radiation shield installation sheets for more detailed installations instructions.
When the chimney passes through a non-combustible exterior wall (e.g. concrete), the angled wall radiation shield
is not required. An opening slightly larger than the chimney can be created through the non-combustible wall. Any
gaps between the chimney and wall can be filled with rock wool insulation and then sealed with silicone.

CHASE ENCLOSURE
If the chimney runs up the outside of the house, we
recommend that it be enclosed in a chase structure. The
chase should be constructed in such a way that it is an
extension of the home (see Figure 15). It should be well
insulated between the footings and the floor of the home to
prevent heat loss. If the climate in your area is mild, insulate
the chase at least to the first firestop. If the climate in your
area is very cold, insulate the chase to the top to keep the
chimney warmer, increase the draft, and reduce creosote
buildup. We also recommend insulating the ceiling of the
chase just as if it were in the attic space. This will prevent
cold air from dropping down through the chase and into the
room where the fireplace is installed (see Figure 15).
Some local codes require that the walls be insulated, vapor
sealed and sheathed with a fire rated gypsum board (see
Figure 15). We strongly recommend this procedure for all
installations to prevent cold drafts from originating in the
fireplace enclosure. If you follow this procedure, we
recommend that you do not insulate the wall above the front
of the fireplace.
REMEMBER: Check local codes concerning installation
requirements and restrictions in your area.
MASONRY CHIMNEY
Installing your PEARL3600 fireplace with a masonry chimney
still requires using EXCEL chimney from the top of the
fireplace to where it will connect to a listed liner that will run
up inside the masonry chimney (see Figure 16).
The stainless-steel liner should be fitted inside the clay liner all the way to the top of the masonry chimney. It is not
meant to replace the clay liner. You can use either the EXCEL liner or any other listed liner to ULC-S635, ULC-
S640 or UL-1777.
Special care is to be taken to make sure that you have a good solid connection between the EXCEL chimney and
the liner. A masonry adaptor (FO-FDM6) was designed specifically for that purpose and is available from your RSF
dealer. It will attach to the liner with 3 stainless steel rivets (provided) and to the EXCEL chimney with 3 screws
(provided).
After mortaring in place, the
connection between the EXCEL
chimney and the liner should not be
visible in order to isolate the heat
released through the liner from the
fireplace enclosure.
As depicted in Figure 16, you must
install at least one 18" length of
EXCEL chimney after the EXCEL
chimney elbow. The uppermost part
of the EXCEL chimney - where it
enters the masonry chimney - must
be a minimum of 12" from the ceiling.
NOTE: If the ceiling is high enough,
you can install one or more EXCEL
chimney lengths directly on the
fireplace before the elbow.

If you use a flexible liner, make sure to be careful when cleaning to ensure that the stainless-steel flexible liner is
not dislodged in any way.
Using an Existing Masonry Chimney
WARNING: If you are considering using an existing chimney, it must first be thoroughly inspected by an authority
having jurisdiction to determine the following:
1. The masonry chimney is well constructed and fully lined, in accordance with Local Building Codes and the
National Building Code of Canada (NBC) or National Fire Protection Association chimney standard (NFPA 211).
2. It has been thoroughly cleaned of any soot or creosote residue and inspected to determine that it is in good
working condition.
3. There is no insulation of any type in contact with the masonry chimney and there is no insulation stuffed
anywhere in the chimney.
4. All the necessary clearances around the masonry chimney, along the complete run of the chimney, are
respected as per NBC or NFPA 211. If the masonry chimney is enclosed in drywall, openings will probably be
required in order to verify clearances at all points.
5. The masonry chimney will only be used for the fireplace and no other appliance.
If major repairs are required to meet the above conditions, a new chimney should be constructed.
To make the hole through the masonry chimney and make the connection to the fireplace, we recommend that you
follow these steps:
1. Sight-in and mark the outline of where the EXCEL chimney will penetrate the masonry chimney.
2. Using a large (¾" - 2") masonry drill bit, drill a hole exactly in the center of the oval outline. With a masonry
hammer and drill, slowly enlarge the hole to the size required. Remember to work from the center out. Be
especially careful with the clay liner behind the brick because three sides of it must stay in place.
3. Bring the stainless-steel liner down from the top of the chimney.
If you are using a rigid liner you will need enough room to secure an elbow to it with at least two screws.
If it is difficult to install rigid stainless steel liner in the existing masonry chimney or for a masonry chimney with
less than 8"x8" inside, a listed stainless steel flexible liner can be used along with a flexible/rigid adaptor (LM-
6LAF) available from your RSF dealer.
4. Install the liner elbow and masonry adaptor on the lower end of the liner.
5. Move the fireplace forward enough to install the EXCEL chimney on the fireplace (elbow and length) then move
the fireplace back into position as you connect the masonry adaptor to the EXCEL chimney.
Using a New Masonry chimney
Since the masonry chimney is not build yet, we recommend that you position your fireplace, install the EXCEL
chimney on it and connect to the first length of liner before building the chimney as explained above and shown in
Figure 16. The liner sections can easily be installed as the layers of brick are being placed. Since this is a new
chimney, we recommend that you build it to the right size, so you do not have to ovalize the liner.
Remember: The stainless-steel liner should be fitted inside the clay liner all the way to the top of the masonry
chimney. It is not meant to replace the clay liner.
HEARTH EXTENSION
The area immediately in front of the fireplace must be protected by a non-combustible material such as brick, tile,
stone, or slate. Refer to Table 1 (G-H) for the depth and width that the hearth protection should extend beyond the
front and both sides of the door opening (see Figure 1). There is no minimum thickness required for the hearth
extension.

PEARL 3600 Owner's Manual 19 RSF Woodburning Fireplaces
BENEATH THE HEARTH EXTENSION
If the PEARL3600 is installed on a non-combustible floor,
the cement board and the spark guard specified below are
not required.
Install the spark guard provided (5" x 36" piece of sheet
metal) halfway under the fireplace and halfway under the
hearth extension and centered on the door opening. The
spark guard will extend 2½" beneath the fireplace. This will
make certain that sparks cannot lodge in this area and
start a fire. If necessary, the provided spark guard can be
cut to the minimum width specified in Table 1 (I).
If you are preparing a raised installation, you will need a
custom made spark guard, either a "Z" shaped spark
guard or a right angle spark guard. The Z-shaped spark
guard must be used if the height between the bottom of
the fireplace and the top of the non-combustible flooring of
the hearth extension is less than or equal to 2 ½". The
height of the Z-shaped spark guard must equal the
distance between the floor and the base of the unit and go
under the hearth extension and the fireplace by at least 2½". If the unit is installed higher than 2 ½" from the top of
the flooring, a right-angle spark guard is necessary. The sides of the right-angle spark guard should be at least 2½"
x 2½" and must be covered with non-combustible material. Any custom made spark guard must have the minimum
width specified in Table 1(I), and be installed centered on the door opening.

REFRACTORY BRICK INSTALLATION
Before lighting your first fire, you must make sure the refractory bricks are properly installed inside the firebox. To
remove any of the refractory bricks, just follow the installation procedure in the reverse sequence. Refer to Figure
18 to identify which refractory brick is the left and which is the right at each step of the installation.
1. Start by placing the rear refractory brick in the firebox (1), then the right and left side (2, 3) refractory bricks.
2. Continue by installing the soft insulation (4) on the bottom of the firebox. It fits tight between the front and the
back refractory brick and between both side refractory bricks.
3. Then install the bottom refractory brick (5).
4. Finally, install the two front refractory bricks (6, 7).
These refractory bricks have been designed specifically for the PEARL3600 and no modifications are required to
ensure a proper fit.
