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 DO NOTs 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.
3. To avoid glass breakage, DO NOT slam the fireplace door.
4. 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.
5. DO NOT overfire the fireplace. If you are unable to slow down the burning rate of the fire or if the
chimney connector behind the top louver glows red, you are overfiring the fireplace.
6. DO operate the fireplace with doors either fully closed or fully open with the firescreen. If the doors are
left partly open, gas and flame can be drawn out of the fireplace opening, creating both fire and smoke
hazards.
7. If you use the fireplace with the doors wide open, install a firescreen (FO-FDFS) to prevent logs and sparks
from burning your floor. Under no circumstances should the fireplace be used without either the firescreen
installed or the doors closed.
8. DO keep all combustible materials (furniture, firewood, etc.) at least 4' away from the front of the fireplace.
9. DO NOT use a fireplace grate or other products not specified for use with 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. 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. If a significant layer of creosote
has accumulated (1/4" or more), it should be removed to reduce the risk of chimney fire.
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. Do not use more than one wax fuel log (e.g. Duraflame) at a time and only with a
firescreen on the fireplace. Use only firelogs that have been evaluated for fireplace use. In Canada, they should
meet the requirements of ULC/ORD-C127-M1990. Refer to the firelog warnings and caution markings prior to
use.

OPEL2 Owner's Manual 4 RSF Woodburning Fireplaces
GENERAL SPECIFICATIONS
THE COMBUSTION CONTROL SYSTEM
Since the doors are sealed, all combustion air must come through the OPEL2's draft control. This control has a
bimetal coil to allow more air when the unit is cold, and less air when the unit is hot, guarding against overheating.
It can be controlled either manually with the lever that is located below the right window frame, or automatically
with an optional electric wall thermostat.
For the first few days, it is best to operate the fireplace with the manual control fully open (moved to the right as
far as possible). Just control the fire as you would any normal fireplace, using one or two logs at a time for a
smaller fire, or more logs for more heat. Once you become familiar with operating the fireplace with the control
open, you can start experimenting with lower settings. Remember: when the fireplace is hot, the control will not
need as much movement to reduce the fire as when it is cold. The bimetal coil will already have shut the damper
part way.
OPTIONS
There are many different ways you can finish your OPEL21fireplace no matter what basic unit you have
purchased (black door: FF-OPAB2, gold door: FF-OPAG2, or pewter door: FF-OPAP2). You can choose to install
louvers – with or without the upper louver – louvers are available in various colors (regular black: FO-OPLB,
regular gold: FO-OPLG, regular pewter: FO-OPLP or classic black FO-OPLC) or no louvers at all (FO-F2).
If you choose to install only the lower louver while bocking off the upper louver on your OPEL2 fireplace, you
MUST install two Gravity Vent Kits (FO-V2). Gravity vent dampers may not be installed on an OPEL2 with a
blocked upper louver.
If you choose to install your OPEL2 fireplace without any louvers, you MUST install the Clean Face Option (FO-
F2) along with two Gravity Vent Kits (FO-V2). Gravity vent dampers may not be installed on a Clean Face OPEL2.
To simplify the installation of thin non-combustible materials such as ceramic tile or sliced brick, we have
designed rock retainer kits. They are not designed or required for full brick or stone. With a Louvered OPEL2, you
can choose to leave all the black metal completely exposed, partially exposed or completely covered with non-
combustible material. For a Louvered OPEL2, consider using the FO-FDK to keep both louvers open while
covering everything else, or the FO-KP2 if your want to cover the upper louver as well. For a Clean Face OPEL2,
consider using the FO-KP2, that will help you cover the entire fireplace facing with the exception of the door area.
Thin materials can also be installed directly on the face of the OPEL2 using high temperature silicone as glue,
without a rock retainer kit.
For increased air circulation and marginally more heat output, you can add the Circulating Internal Blower (FO-
FDHB5-N) to your Louvered OPEL2 or the Inline Fan (FO-CIF) to your Clean Face OPEL2.
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 Kit (FO-V2). The gravity vent distributes hot air to these rooms and
requires no blower to assist its operation. With a Louvered OPEL2 (both louvers unblocked), you could consider
installing Dampers (FO-D) on your gravity vents. The dampers will enable you to choose between sending the
heated air to the gravity vent outlet or keeping it in the fireplace room.
For constant heat, day and night, you will be surprised by what the Thermostat Option (FO-FDHC4) can do for
you. This option provides you with the necessary parts to automatically control the draft control via a wall
thermostat. It will keep your room temperature as even as though you were heating with oil, gas or electricity,
except you will find wood heat more comfortable.
To maximize the distribution of the heat generated by your OPEL2 fireplace throughout many rooms and different
floors, consider the Central Heat Option. With our Central Heat Blower (FO-FDHB6-1), you can use the house
central heating ducts or dedicated ducts to circulate the fireplace heat to one or many rooms. The Central Heat
Control (FO-FDHC6) will enable automatic control of the Central Heat Blower via a wall thermostat and thermal
switch. The Zone Heat Control (FO-FDHCZ1) along with Zone Damper Kits (FO-FDHCZ2) will provide the same
features as the Central Heat Control but for more than one heating zone. If you wish to install the Central Heat
Blower on a Clean Face OPEL2, you will need the Central Heat T (FO-T) that will enable you to connect the
central heat duct along with the left gravity vent on the fireplace.
1You can also refer to the configured option list on page 24.

OPEL2 Owner's Manual 5 RSF Woodburning Fireplaces
For a simpler way to circulate a moderate amount of warm air from the fireplace to another room, we offer the
Heat Dump Kit (FO-HD) which uses a smaller fan than the Central Heat Blower. It is most often used to provide
supplemental heating to a basement room when the fireplace is on the main floor but it can also be used to send
the warm air upstairs.
To remove accumulated ashes from the firebox, simply shovel them in to a metal container. If you have chosen to
install your OPEL2 fireplace with a lower louver, you may find the optional Ash Pan Kit (FO-AP) very convenient.
You remove the plug from the firebox and sweep the ashes into a hole to the ash pan. When the ash pan is full,
simply remove the ash pan by the bottom louver and dispose of the ashes properly.
This fireplace has been specially designed to combine high efficiency with the elegance of a wood burning fire.
Most often you will take advantage of the high efficiency and the control possible with your new OPEL2 wood
burning fireplace. If you would like to enjoy the sight and sound of an open fireplace, or simply have less heat
output in a warmer weather you may want to install the optional OPEL2 firescreen (FO-FDFS).
The OPEL2 fireplace is very efficient and clean burning but if you would like to go a step further, you could
consider the Catalytic Kit (FO-FDCCO). The Catalyst ignites gases in wood smoke that would otherwise
accumulate in the form of creosote in the chimney. As a result you get less creosote and more heat from your fire
at low to medium burn rates.
NOTE: Many 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 23 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.

No combustible mantel can be installed lower than 23" above the top of the firebox opening. A combustible
mantel cannot be wider than 12".
For combustible mantel depths not mentioned in the list above, you can interpolate the minimum installation
height between the two closest mantel depths. For example:
•Mantel depth to be installed: 9 ¼"
•It is between 8" and 10" with corresponding installation heights of 28" and 31"
•So: ((9.25 – 8) / (10-8) x (31-28))+28 = 29.875 = 29 7/8"
•Minimum installation height of a 9 ¼" mantel: 29 7/8" above the firebox opening.
If the combustible mantel 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 it depth.

OPERATION
AIR CONTROLS
Unlike most open fireplaces, RSF fireplaces don’t
have flue dampers. Instead, the system is sealed
by closing the door, and the amount of air entering
the firebox is controlled by the combustion air
control lever on the front of the fireplace on the
right below the door (see Figure 2) which can be
moved left or right. Setting the air control lever all
the way open (towards the right) will allow the
maximum amount of air into the firebox. Closing the
air control (towards the left) will reduce the amount
of air entering the firebox.
Bi-metallic Damper
The bi-metallic damper is a unique feature built into
your OPEL2 fireplace. As the fireplace heats up it
will activate the bi-metallic damper. This will
automatically begin to shut down the air entering
the firebox, slowing the combustion process. This
will save you wood in the long run, and prevent the
fireplace from overheating and causing potential damage to the firebox. We suggest that the combustion air
control lever is used as the primary control to limit the oxygen entering the firebox, and that the bi-
metallic damper is left as an additional safety system.
Outside Air Control
The OPEL2 has been designed to offer you the choice to use outside air or inside air for combustion. You will find
a sliding door behind the bottom louver and below the firebox. Push the sliding door towards the back to select
outside air or pull it toward the front to select inside air as the combustion air. Because outside air is generally
colder and denser it will help to start the fire. In some cases this fresh air will also help compensate for negative
pressure problems within the house; however it will not prevent the fireplace from smoking in a severely
depressurized house. If the fireplace is installed in a mobile home, the outside air has to be used as combustion
air.
BURN TIME VS. HEAT OUTPUT
The faster your fireplace burns the more heat it will create; however, faster fires result in much more hot air flow
up the chimney which means you are sacrificing efficiency. Fast burning fires (lots of air) go through much more
wood than slow burning fires. To get the most out of your OPEL2 fireplace, adequately adjust the combustion air
control lever at the appropriate time. If the fire seems to be burning too quickly, turn the air down. If the fire is
smoldering and there are no visible flames, turn the air up. This way you’ll always be getting the most out of your
fuel.
FUEL
All modern high efficiency fireplaces and woodstoves are designed to burn best with seasoned cordwood.
Seasoned wood can be defined as wood that has been cut, split and let dry under cover for a minimum of 6
months, preferably a year or more. Dry seasoned wood generally contains less than 20% moisture content.
Attempting to burn fuel with a high moisture content will be difficult and result in lower efficiency, increased
creosote buildup and dark deposits on the glass. It’s possible to burn a very large amount of wood, and get very
little heat if the wood is wet.
The type of wood you select is also important. All types of wood give off more or less the same number of BTU’s
per pound. Since softer woods are less dense than hardwoods it is possible to put more weight of hardwood in
the firebox; in other words all woodburning appliances will burn longer and more evenly with hardwoods. Never
burn scrap, garbage, treated wood or driftwood as they produce much more pollution and can corrode the firebox
and chimney as well. Burning large amounts of paper, cardboard, mill ends or construction waste can easily over
fire and damage the fireplace or even ignite a chimney fire if the flue is dirty.

OPEL2 Owner's Manual 8 RSF Woodburning Fireplaces
FIRST FIRES
You will experience a slow start-up during the first few fires. The refractory bricks lining the firebox contain
moisture from manufacturing and require a few hot fires to evaporate the moisture. While there is still moisture in
the bricks, they will be black with smoke deposits. When the moisture has dissipated, the bricks will turn white.
Unlike cast iron stoves, there is no need to cure the fireplace itself by starting with small fires and progressively
larger ones. Feel free to light a large fire from the very start.
You will experience a slight odor during the first few fires. This odor comes from curing paint and oil burning off
the metal. The odor may be strong enough to set off your smoke detector. Open the doors and windows to allow
the room to properly ventilate.
Before the first fire, be absolutely sure to use regular dish soap and water to wipe off all fingerprints and
debris from the gold plating if you have chosen this option. The plating cures during this first fire, the
acid from your finger prints will permanently etch the gold plating.
LIGHTING
Ensure that the combustion air control lever is all the way in the open position. You will want as much air as
possible for the lighting process.
Start by laying your fire starter and kindling. Traditional fire starter is crumpled newspaper; make sure to use
enough to light the kindling (5-6 pieces should do). Next lay the kindling crisscrossed over the newspaper. Using
plenty of kindling ensures that the chimney will heat up quickly and establish a strong draft, never use any
flammable liquids. Light the paper and close the door most of the way, but don’t shut it completely. If the door is
positioned correctly you will see air rushing into the fireplace, this will help the lighting process.
Once the kindling is lit and sustaining fire, you can add some small pieces of seasoned cordwood. Use the
andirons in front to help position the cordwood so as not to flatten and smother the fire you’ve just created.
Always add at least 3 pieces of cordwood. Position your cordwood in a manner that the fire will hit several pieces
as it rises and has air gaps to flow through. Continue to leave the door slightly open until the cordwood is lit. Close
the door completely when the fire is established, if the fire goes out you’ve shut the door too early.
To get maximum efficiency out of your fireplace you will want to adjust the amount of air entering the firebox at the
appropriate times. Gauge how much to close the combustion air by how the fire reacts once the combustion air
control lever has been moved. If the fire goes out and begins to smolder, there’s too little combustion air entering
the firebox. If there’s no change to the burn pattern, you can continue to close the combustion air further.
Eventually you should be able to close the combustion air all or most of the way. There should always be visible
fire inside the firebox at every step of the process.
WARNING: DO NOT USE A GRATE OR ELEVATE THE FIRE.
REFUELING
The door should be opened slowly to keep smoke from spilling into your room. If you have a problem with smoke
spillage, check to see that all kitchen and bathroom fans have been shut off. They can cause negative pressure in
the house which pulls smoke out of the fireplace.
NOTE: The central heat and internal blowers, if installed, should be shut off during refuelling to prevent smoke
from spilling out of the fireplace.
TROUBLESHOOTING PROBLEMS
If smoke comes into the house when the door is opened:
•You may have opened the door too quickly and created a suction of air into the room, this can be avoided by
opening the door more slowly.
•Ensure your chimney is clean and your chimney cap is not plugged. Chimney caps with screens are more
likely to become clogged with creosote buildup.
•Make sure you have adequate chimney height for your system. Refer to the Chimney section of this booklet
and make sure to take altitude, and number of elbows into consideration.

OPEL2 Owner's Manual 9 RSF Woodburning Fireplaces
•If you have purchased the central heat kit option or the circulating internal blower, make sure the blower is off
before opening the door.
•Check to see if other fans in the home are running, particularly a kitchen range hood, or bathroom exhaust
fan. This can affect the pressure in the home.
•Try opening a window near the fireplace a little, this will equalize the pressure in the home and should correct
a draft problem. Once proper draft is established the window can be closed.
•Make sure you’ve used enough kindling to establish a hot fire quickly. The most likely time that smoke will
enter the home is during the lighting process.
MAINTENANCE
GENERAL CLEANING
The high heat paint and plating can be cleaned with a soft damp cloth. Use a mild detergent and water. Do not
use abrasive cleaners.
PAINT
You can touch up the face of the OPEL2 with Stove Bright Metallic Black high temperature paint which is
available at most fireplaces dealers. Follow the directions outlined on the spray can. DO NOT attempt to paint the
fireplace while it is still warm. Keep the spray can away from any source of heat or open flame. Ensure that there
is adequate ventilation in the room from the time you start painting until the paint is dry. Stove Bright is available
in a wide range of colors if you want to change the color of your OPEL2.
We recommend that you take the time to protect or remove any item that you do not want to paint such as: the
door glass, the plated door, the fireplace surroundings, etc. The glass can be removed from the door but you will
have to replace the window gasket.
GLASS CLEANING
In a controlled combustion firebox, temperatures are not always high enough to keep the glass perfectly clean. A
good hot fire once a day usually cleans off most of the deposits that have accumulated. Remember: the drier the
wood and the hotter the fire, the cleaner the glass. A word of caution: although heat will not break the glass,
impact can. Be careful not to hit the glass.
WARNING: NEVER CLEAN THE GLASS WITH AN ABRASIVE CLEANER. USE ONLY A CLEANER
RECOMMENDED BY YOUR DEALER. NEVER CLEAN THE GLASS WHILE IT IS HOT, A SERIOUS BURN
CAN RESULT. THERE ARE A NUMBER OF EXCELLENT WOOD STOVE GLASS CLEANERS AVAILABLE
WHICH ARE FAR SUPERIOR TO REGULAR GLASS AND OVEN CLEANERS FOR WOOD STOVE
APPLICATIONS.
CHIMNEY CLEANING
Check the chimney for creosote buildup every week or so until experience shows how often you need to clean it.
A buildup of ¼" or more should be cleaned before more creosote accumulates. Use an 7" round brush. The baffle
in the firebox can be removed to gain access to the flue from below.
To remove the baffle, first remove the secondary air tube. Simply unscrew the secondary air tube on the left side,
slide the tube toward the right until the left end drops out of its hole. Slide the tube back towards the left to get the
right end out of its hole. To remove the baffle, push up and slide it off the brackets. Replace both the baffle and
the secondary air tube as you removed them and be sure to have the holes on the secondary air tube facing
toward the front.
DISPOSAL OF ASHES
Remove the ashes before they become too deep, i.e., before you have a spillage problem when you open the
door.

OPEL2 Owner's Manual 10 RSF Woodburning Fireplaces
The ashes should be placed in a metal container with a tight-fitting lid. The closed container of ashes should be
placed on a non-combustible floor or on the ground, well away from all combustible materials pending final
disposal. If the ashes are disposed of by burial, or otherwise locally dispersed, they should be retained in the
closed container until all cinders have thoroughly cooled.
DOOR ADJUSTMENT
The door latch and hinges can be adjusted for proper sealing of the doors. It is normal to push on the handle to
close the doors. Add some of the high temperature grease provided to the door latch and hinges at least annually.
To check for a proper door seal, insert a thin sheet of paper between the doors and the front of the fireplace and
latch the doors. Pull gently but firmly on the sheet of paper. If the paper either tears or is hard to retrieve, the
adjustment is correct. Repeat this procedure along all sides of the doors.
The most important factor for controlling the burning rate of the OPEL2 is a good seal on the door gasket. If the
door gasket is worn or damaged to the point where the seal is not adequate as described above, then remove
and replace the gasket. Replacement kits are available from your
RSF dealer.
To insure a proper seal, you need to adjust the tightness of the
doors against the front of the fireplace as follows:
1. To tighten the center area of the doors, turn the Allen key
screw clockwise (see Figure 3).
2. To tighten the side area of each door, start by slightly
loosening the nuts below the door hinges of the right hand
door.
3. Close the door without latching it but make sure the door pawl
is engage in the door latch.
4. Adjust the door so that the joint between the two doors is
straight and level.
5. Push the right hand door firmly against the facing of the
fireplace to insure a good seal while tightening the hinge nuts.
Use a screw driver on the bottom of the hinge pin and a
wrench to tighten the nut (see Figure 4).
6. Continue by loosening the nuts below the door hinges of the
left hand door.
7. Adjust the left door so that the top arch and the joint are flush
with the right hand door.
8. With the right hand door open, push the door firmly against the
facing of the fireplace to insure a good seal while tightening
the hinge nuts.
9. Verify the seal with the sheet of paper as described above.
You may need to retighten the door latch after adjusting the
doors.
NOTE: An improperly adjusted door seal can have a significant
effect on the performance and durability of the fireplace. A poorly
adjusted door can result in reduced efficiency, over firing,
excessive wood consumption and premature fireplace failure.
GOLD PLATING
If you have gold doors or gold louvers, you will be happy to know
that they will not tarnish. However, they are not scratch resistant. Use only mild soap and warm water to clean the
gold when the surface is cool. The use of any household cleaner, such as Windex, abrasive cleaners, or any form
of acid, may permanently etch or remove some of the gold plating. Before the first fire, make sure to clean all
fingerprints and other deposits on the gold plating. Since the plating cures during the first fire, fingerprints and
other deposits will permanently etch the gold plating.

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.
Remove the fireplace doors. Store them in a safe place until the installation and finishing work is finished. Be
aware that heavy duty cleaning products or acid solutions will permanently damage the plating.
LOCATION
Your OPEL2 fireplace may be installed in many different ways (see Figure 5) without any special floor
reinforcement. We recommend that you take the time to plan your entire installation (fireplace, chimney, and
options) before beginning the actual installation (refer to Figure 6 and Figure 7).

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 SPACES 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. 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.

CEILING CLEARANCE
Ceiling clearance is the distance from the base of the fireplace to the ceiling. If you vent the fireplace enclosure,
you can then have a lower ceiling clearance as specified in Table 1 (C) for a vented enclosure.
For a vented enclosure, you MUST install regular venting 3"x10" grilles or larger into holes cut within 1' of both the
floor and the ceiling, to allow room air to circulate through the fireplace enclosure and reduce heat buildup. These
venting grilles may be placed vertically or horizontally.
Under no circumstances should the distance between the ceiling firestop and the base fireplace be less than the
dimension specified in Table 1 (C).
OUTSIDE AIR DUCT
After the fireplace is correctly positioned, connect the outside air inlet to the outside (see Figure 8).
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.
The air inlet should never be less than 5' below the
top of the chimney flue 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.
Both 4" and 5" connecting sleeves are provided with the
fireplace.
1. Find a convenient location for the combustion air
duct and outside air inlet. The outside air inlet can
be above or below floor level.
2. 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.
3. Place the insulated flexible duct over the round
sleeve on the outside air inlet. At both ends,
carefully pull back the insulation and plastic cover,
exposing the flexible duct. Then at each end, attach the duct with metal screws to the air inlet and to the
fireplace connecting sleeve. Carefully push the insulation and cover back over the duct. Tape the plastic
cover in place with 2" aluminium duct tape.
CAUTION: WHEN RUNNING THE DUCT AROUND CORNERS, BE SURE TO PREVENT CRIMPING THE
DUCT THAT WOULD RESTRICT THE COMBUSTION AIRFLOW.
CHIMNEY
This fireplace is certified for use with 7" ICC Model EXCEL chimney only. Please refer to Table 1 (D-E) for the
minimum and maximum chimney height permitted with the OPEL2 fireplace.
We recommend that the minimum height be increased by approximately 1' for every 2000' elevation above sea
level. Every 30° or 45° elbow also increases the minimum height by 1'. For example, if you are living 6000' above
sea level, your chimney should terminate at least 15' from the top of the fireplace (12' + 3' for the 6000'). See
Table 3 for more precise recommended flue heights.

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 13" square (the opening can be slightly bigger, up to 13 ½", 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 9.
WARNING: A RADIATION SHIELD MUST BE INSTALLED AT EACH FLOOR WHERE THE CHIMNEY
PASSES THROUGH.
3. Remove the flue adapter from the fireplace, put the
screws aside. Install the flue adapter on the first
chimney length and secure it with the screws
provided. Reinstall the flue adapter on the fireplace
and secure it with the screws you have put aside
earlier. Assemble the rest of the chimney.
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. Put the roof flashing into place. Seal the joint
between the roof and the flashing with roofing tar. For
sloping roofs, place the flashing under the upper
shingles and on top of the lower shingles. Nail the
flashing to the roof using roofing nails.
If the chimney is enclosed to the roof:
•In USA: use a vented flashing;
•In Canada: use a vented flashing, or a roof
radiation shield with a regular flashing.

5. Place the storm collar over the chimney and flashing. Seal it around the chimney with silicone sealer (DO
NOT use roofing tar).
6. 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 10 and Figure 11 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 other section with 3 metal
screws at the joints.
2. Install enough lengths to obtain the desired offset. Secure each joint with 3 metal screws.
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).

OPEL2 Owner's Manual 17 RSF Woodburning Fireplaces
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 12). 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 to insulate
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 12).
Some local codes require that the walls be insulated,
vapor sealed and sheathed with a fire rated gypsum
board (see Figure 12). 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 OPEL2 fireplace with a masonry chimney
still requires using EXCEL chimney from the top of the
fireplace to the wall where it will connect to a listed liner
that will run up inside the masonry chimney (see Figure
13).
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-
FDM7) 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 13, 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 10"x10" inside, a listed stainless steel flexible liner can be used along with a flexible/rigid
adaptor (LM-7LAF) 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 13 . 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 but if you choose
to use a 6"x10" clay liner you will need to ovalize the stainless steel liner to fit into the clay 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.
FRAMING
The enclosure walls can be framed with any suitable materials (2x4 or 2x6 studs, plywood, gypsum board, etc.).
Because of the high heat output potential of the OPEL2, combustible materials must NOT go closer to the
fireplace than the standoffs, top, back and sides.

OPEL2 Owner's Manual 19 RSF Woodburning Fireplaces
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.
BENEATH HEARTH EXTENSION
If the OPEL2 is installed on a non-combustible floor, the spark guard specified below is 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 (see Figure 14).
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.
NOTE: Custom-made spark guards are not supplied.
MANTEL
Refer to Table 1 (J) for the maximum depth of the
mantel and its installation height. Wood or other
combustible mantels must be placed as specified in
Table 1 (K) and illustrated in Figure 1.
Masonry and other non-combustible mantels can
be placed directly above the top of the fireplace
facing or higher. If the noncombustible 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 you install a combustible mantel with side posts
and/or with a combustible mantel support
underneath, similar to the one shown in Figure 15,
make sure to respect the clearances specified in
Figure 15.

MANDATORY OPTIONS WITH THE CLEAN FACE
When installing a Clean Face (FO-F2) on your OPEL2, you MUST install the intake duct (part of FO-F2) to
provide sufficient air to the unit along with two Gravity Vent Kits (FO-V2, sold separately) to provide an evacuation
path for the heat. Neglecting to install either one of these will result in overheating of the unit and may put your
safety at risk. Refer to each option's installation instructions for particular details.
Use only genuine RSF parts. The use of any substitutes will decertify the system and may put your safety at risk.
REFRACTORY BRICK INSTALLATION
Before lighting your first fire, you must make sure the
refractory bricks are properly installed inside the firebox.
This is easily accomplished with the following
instructions. To remove any of the refractory bricks, just
follow the installation procedure in the reverse
sequence. Refer to Figure 16 to adequately identify
which refractory brick is the left and which is the right at
each step of the installation.
1. First, pass the baffle (11.6.P) through the front
opening of the fireplace. Then turn it parallel to the
opening with the narrower portion on top. Slide the
baffle up above the bracket at the top of the firebox
until it is as far back as it can go.
2. Then install both back refractory bricks (left 11.11.P
and right 11.12.P).
3. Continue by installing both side rear refractory
bricks (left 11.9.P and right 11.10.P). Just insert the
top corner of each refractory brick behind the
bracket and slide it against the back refractory
bricks.
4. Next install the front side refractory bricks (left 11.7.P and right 11.8.P) with the finished side towards the front
of the unit.
5. Then install both left and right bottom refractory bricks (left 11.14.P and right 11.15.P) before installing the
bottom central refractory brick (11.18.P).
6. Finish by installing both front refractory bricks (left 11.17.P and right 11.16.P)
These refractory have been designed specifically for the OPEL2 and no modifications are required to ensure a
proper fit.
GAS LOG INSTALLATION
The OPEL2 can be converted into a gas fireplace as long as you keep the combustion air control lever all the way
open (towards the right) and make the modifications to the fireplace as explained below. This is to allow enough
air for an adequate and safe operation of the gas log. You can use any gas log set up to a maximum of 35,000
BTUs that is listed to ANSI Z21.60/CSA 2.26.
WARNING: THIS FIREPLACE HAS NOT BEEN TESTED WITH AN UNVENTED GAS LOG SET. TO
REDUCE RISK OF FIRE OR INJURY, DO NOT INSTALL AN UNVENTED GAS LOG SET INTO THIS
FIREPLACE.
Remember that the installation of the gas line should be done by qualified personnel. All gas installations should
be in accordance with local ordinances and the appropriate Gas Code.
We do not require any minimum clearances between the side or the top of the firebox and the gas log set.
However, any clearances stated by the gas log set manufacturer must be maintained. You may install the gas
valve inside the firebox if the gas log set manufacturer allows this in its installation instructions, and if the required
clearances are met.
