3. Fuel
3.1 Recommended Fuel
Wood burner performance depends greatly on the fuel used. Good firewood has been cut to
the correct length for the appliance, split to a range of sizes and stacked in the open until its
moisture content is down to 15% to 20%. Proper fuel makes it easier to regulate heat and keep
the wood burner and flue in better condition.
Use split pieces of wood, they will burn better than logs. Make sure to have various size of
wood.Thin firewood should be used to get higher thermal power, use it after lighting the fire for
a faster response as more heat is needed. Use thick wood for a slower combustion when less
heat is needed or for overnight fire. If necessary, when starting the fire, burn a combination of
thin and thick firewood.
Store firewood in a dry, ventilated place protected from the rain for one to two years depending
on the storage and weather conditions.
ENGLISH
DO NOT BURN GARBAGE OF ANY KIND, COAL OR CHARCOAL, TREATED, PAINTED OR
COATED WOOD, PLYWOOD OR PARTICLE BOARD, FINE PAPER, COLORED PAPER OR
CARDBOARD, SALT WATER DRIFTWOOD, MANUFACTURED LOGS CONTAINING WAX OR
CHEMICAL ADDITIVES, RAILROAD TIES AND LIQUIDS SUCH AS KEROSENE OR DIESEL
FUEL TO START A FIRE.
Do not burn manufactured logs made of wax impregnated sawdust or
logs with any chemical additives. Manufactured logs made of 100%
compressed sawdust can be burned with caution in the number of these
logs burned at one time. Start with one manufactured log and see how
the cookstove reacts. Never use more than two manufactured logs.

It is prohibited to put or store: alcohol, gasoline, liquid fuel, flammable materials,
ashes, paper and wood in the accessory compartment.
4.2 Cooking
Cooking can be done in the stainless steel oven, using the cooking grills and the trays provided
with the cookstove. It can also be done in the combustion chamber, using the cooking grils only.
Do not use the trays in the combustion chamber.
The panoramic windows allow you to see the cooking or baking without having to open the
door. The door’s integrated thermometer simplifies the reading of the oven temperature. The
temperature indicated by the thermometer is only used as a reference. During cooking, keep the
oven door closed to keep a constant temperature.
4.3 First Fires
Before ignition, make sure the chimney is clean and clear. The cookstove startup must be done
only when all the installation steps for the cookstove and the chimney have been completed.
During the first fires, the cookstove will give off an unpleasant smell along with a light smoke.
This has to do with the hardening of the paint process. The paint heats up, hardens, and
adheres to metal. The smell and the smoke will disappear when the cookstove has been heated
for several hours. Increase the fire intensity gradually. Open a window. Even though the smoke
and the smell are unpleasant, they are not toxic.
4.4 Lighting a Fire
Load a generous amount of firewood, placing a layer of wood chips or thin firewood and another
layer of thicker wood on top. You must leave the pieces crossed and with enough separation
between them to allow proper air flow.
Light the first layer of wood chips or thin wood using fire-starters or special lighting products,
if necessary.
Leave the door ajar, so that enough air can enter for the fire to light quickly.
Once the wood is well-lit, wait until the temperature is high before completely closing the door
(10 to 45 minutes, depending on factors like wood, air circulation, etc.) and adjust the air inlet.
If you find that the volume of flames decreases, or the fire tends to go out and the smoke inside
the fireplace increases, open the air intake more or repeat the previous step.
ENGLISH
When reloading, if there are not enough embers to light the new load of wood, open the door
and the air inlet.
DO NOT USE FLAMMABLE LIQUIDS SUCH AS GASOLINE, NAPHTHA, FUEL OIL, MOTOR
OIL, OR AEROSOLS TO START OR REKINDLE THE FIRE.
DO NOT LEAVE THE COOKSTOVE UNATTENDED WHEN THE DOOR IS SLIGHTLY OPENED.
ALWAYS CLOSE AND LATCH THE DOOR AFTER THE FIRE IGNITES.
Installation and operation manual - Atlas woodburning cookstove
Page 11
4.5 Maintaining Wood Fires
4.5.1 General Advice
Wood burns best in cycles. A cycle starts when a new load of wood is ignited by hot coals and
ends when that load has been consumed down to a bed of charcoal about the same size as it
was when the wood was loaded. Trying to produce a steady fire by placing a single log at regular
intervals is not recommended. Always place at least three, and preferably more pieces on the
fire at a time so that the heat radiated from one piece helps to ignite the pieces next to it.
Prolonged and continuous use at a very low rate of combustion or with very wet
wood can cause highly flammable creosote to build up in the flue.
Burning in cycles means the stove door does not need to be opened while the wood is flaming.
This is an advantage since it is preventing smoke leaking from the stove when the door is opened
as a full fire is burning. This is especially true if the chimney is on the outside wall of the house.
ENGLISH
If the door must be open while the fire is flaming, fully open the air control for a few
minutes then open the door slowly.
4.5.2 Ash Removal
Ash should be removed from the firebox every two to three days. Ash should not accumulate
excessively in the firebox since it will affect the proper operation of the cookstove.
The best time to remove ash is when the stove is relatively cold, but there is still a little chimney
draft to draw the ash dust into the stove and prevent going out into the room.
Ashes should be placed in a tightly covered metal container. The container must be placed on a
non-combustible floor or on the ground well away from all combustible materials.
Ashes can contain hot embers that can stay hot for several days. If the ashes are disposed of
by burial in soil or otherwise locally dispersed, they should be kept in the closed metal container
until they are completly cooled. No other waste should be placed in this container.
NEVER STORE ASHES INDOORS OR IN A NON-METALIC CONTAINER OR ON A WOODEN
DECK.
4.5.3 Raking Charcoal
When it is time to reload the stove, start by removing the ashes first, then rake charcoal towards
the front of the firebox before reloading. Most of the remaining charcoal will be at the back of
the firebox, furthest from the door. Rake the coals towards the door before loading.
Page 12
Installation and operation manual - Atlas woodburning cookstove
Raking the coals is useful for two reasons. First, it brings them near where most of the combustion
air enters the firebox. This will ignite the new load quickly. Secondly, the charcoal will not be
smothered by the new load of wood. When the embers are simply spread inside the combustion
chamber, the new load smoulders for a long time before igniting.
4.5.4 Firing Each New Load Hot
Place the new load of wood on and behind the charcoal, not too close to the glass. Close the
door and open the air control fully until the firebox is full of flames, the wood has charred to
black and its edges are glowing red. Firing each load of wood hot accomplishes the following
things:
− Removes surface moisture from the wood,
− Creates a layer of char on the wood, which slows down the smoke release,
− Heats the firebox components so they reflect heat back to the fire, and
− Heats the chimney so it can produce strong, steady draft for the rest of the cycle.
Although it is important to fire each new load hot, do not allow the fire to burn at full intensity
for more than a few minutes.
THE COOKSTOVE SHOULD NOT BE LEFT UNATTENDED WHILE A NEW LOAD IS BEING
FIRED HOT.
DO NOT OVERFIRE.
Overloading the appliance with firewood decreases performance, reduces energy
efficiency and accelerates the wear and tear of the appliance. Do not exceed
the maximum load of firewood of 7 kg. Overloading the appliance voids all the
manufacturer’s warranties.
4.6 Adjusting Primary and Secondary Air Inlet
The control of the primary and secondary air inlet is simultaneous and is done with a single
regulation control, located under the combustion chamber door.
The optimum regulation of the air inlet can vary according to various factors, such as the
chimney flue, the temperature of the cookstove and, the quality of the firewood (moisture, size
and shape).
ENGLISH
Do not alter the air regulation control to increase firing for any reason.
In order to avoid burns while regulating air flow and opening the doors, always use
the cold hand provided with the stove.

4.6.1 Regulating the air during lighting
ENGLISH
FERMÉ OPEN
OUVERT
Opening the air inlet completely is mandatory during the lighting, and it is recommended to leave
the door ajar during lighting as well, in order to avoid condensation of fumes on the glass. Wait
enough time (until the hearth has warmed up) before starting to regulate the air inlet.
4.6.2 Regulating the air during combustion
Once the device is hot enough, has a good reserve of embers and the flame is well-lit one can
regulate the air inlet to achieve good combustion and performance.. The air intake may be
regulated to an opening of 15% - 40%. During the operation of the heater you must not
completely close the air inlet.
Page 14
Installation and operation manual - Atlas woodburning cookstove
5. Cookstove Maintenance
This cookstove will give many years of reliable service if used and maintained properly. Some of
the internal components of the firebox, such as vermiculite and baffle will wear over time under
intense heat. Defective parts should always be replaced with original parts. Firing each load
hot to begin a cycle will not cause premature deterioration of the cookstove. However, letting
the cookstove run with the air intake fully open for the entire burn cycles can cause damage
over time. The hotter the cookstove becomes throughout burn cycles, the more quickly its
components will deteriorate. For this reason, the cookstove should never be left unattended
while a new load is being fired hot.
5.1 Cleaning and Painting the Cookstove
Painted surfaces can be wiped down with a soft, dry cloth. If the paint is scratched or damaged,
it is possible to repaint it with a heat-resistant paint. Do not clean or paint the cookstove
when it is hot. Before painting, the surface should be sanded lightly with sandpaper and then
wiped off to remove dust. Apply two thin layers of paint. For best results, use the original paint,
available in aerosol cans.
It is very important not to wet the wood burner with window-cleaner, water or special cleaning
products. Heatproof paint is not waterproof.
ENGLISH
5.2 Vermiculite Slabs and Baffle
Before installing the slabs and the baffle, ensure that none are broken or damaged in any way,
and replace the damaged ones. Check for damage at least annually and replace any broken or
damaged ones with new ones.
5.3 Combustion Chamber
The cookstove cleaning frequency depends on the type and quality of combustible used. A high
humidity rate, ashes, soot, or chemical components in the wood could increase the number of
cleanings necessary. Therefore, it is important to pay attention to the combustible used.
To get the maximum performance from the cookstove, ashes should be removed regulary. The
use of a personal, central, or commercial vacuum cleaner to clean up the cookstove is not
recommended. Ash particles can damage the vacuum engine. Furthermore, hot ashes could
ignite the content of the vacuum. The use of a specialized ash vacuum is highly recommended.
The ashes must be stored in a metallic container with a waterproof lid. This closed container
should be put on a noncombustible surface, away from any flammable material. If the ashes are
meant to be buried or locally dispersed, they should be kept in a closed container until they are
completely cold.
5.4 Grills and Trays
Clean trays like regular dishes. Clean grills with a brush and soft soap.
5.5 Glass Maintenance
Do not clean the glass when the cookstove is hot. To clean the glass, first spray the cleaning
product on a cloth and then proceed to clean the glass only, without wetting the rest of the door.
Window-cleaners and special products often contain chemicals that attack the paint and the
ceramic fibre seals and cause oxidation of the metal parts.
Installation and operation manual - Atlas woodburning cookstove
Page 15
Never use an abrasive cleaner on the window. Do not clean the window when it’s hot. Do not
force, hit, slam, or do anything that could weaken the glass door. Do not use the cookstove if
the window is missing, cracked, or broken.
5.5.1 Replacing the Glass Door and the Glass Gasket
The glass used in the this cookstove is 4 mm thick, and was tested to reach temperatures up to
1400º F. It has the following dimensions :
− Oven (W x H): 20" x 13 ⅛"
− Combustion chamber (W x H): 20" x 16"
If the glass breaks, it must be replaced with one having the same specification. Contact your
dealer to obtain a genuine replacement part.
Tempered glass or ordinary glass will not withstand the high temperatures of the
cookstove.
ENGLISH
To replace the glass, follow the steps below :
1. Remove the door from its hinges and lay it facing down on a soft
surface such as a cloth or a carpet.
2. Remove the screws that holds the brackets in place.
3. Remove the glass.
4. Install the gasket all aroung the new glass (see image).
5. Reinstall the new glass.
5.5.2 Replacing the Door Gasket
To maintain optimal performance, the door
should always be perfectly sealed with the
combustion chamber. The gasket must be
inspected periodically to get a tight seal.
With time, the door gasket will compress and
harden which will allow air to infiltrate. You can
test the condition of the gasket by closing and
locking the door on a piece of paper. Check
the periphery of the door. If the paper slides
easily at any place around the door, it is time
to change the gasket.
Figure 7: Verifying the door seal
The right diameter and density of the gasket are important to maintain a tight seal. Refer to a
dealer for a genuine replacement part. See section "13. Exploded View and Parts List" for more
details.
Put the door facing down on a soft surface such as a cloth or a carpet. Remove the gasket
and use a screwdriver to scrape away the old adhesive. Apply high temperature sealant in the
groove of the gasket. Push the gasket into the groove. Do not stretch the gasket while installing.
Keep approximately ½ inch longer when cutting and then push it into the groove. Push away the
exceeding fibres under the gasket. Close the door and do not use the cookstove for 24 hours.

6. Chimney Maintenance
6.1 Why Sweep the Chimney?
Wood smoke can condense inside the chimney and the chimney connector, forming a flammable
deposit called creosote. If the creosote builds up in the evacuation system, it can combust when
the fire is very hot. An extremely hot fire can progress to the extremity of the chimney. Severe
chimney fires can damage even the best chimneys.
Smouldering fires can quickly cause a thick layer of creosote. When those are avoided, the gases
coming out of the chimney are almost transparent. Creosote is therefore formed more slowly.
Your new cookstove has the necessary characteristics to help you make clean fires producing
little or no smoke. Therefore, less creosote will accumulate in the chimney.
6.2 Cleaning Frequency
It is not possible to predict how long or how much creosote will form in the chimney. It is
important, therefore, to check monthly for deposits in the chimney until the rate of creosote
formation is known.
The chimney must be inspected regularly during the heating season to determine if creosote
buildup has occurred. If a significant layer of creosote has accumulated (3 mm or more), remove
it to reduce the risk of a chimney fire.
ENGLISH
Weekly cleaning may be necessary in mild weather, while monthly cleaning may be sufficient in
the colder months. Even though creosote is slowly forming in the system, the chimney should
be inspected and cleaned at least once a year.
Contact the municipal or provincial fire department for information on how to handle a chimney
fire. Have a clearly understood plan for managing a chimney fire.
It is recommended to clean the chimney system at the end of each heating season. During
summer, the air is more humid and with minimum air circulation in the appliance, creosote or the
soot left in the pipes can produce an acid that will accelerate the corrosion process of steel and
may perforate it prematurely. Consequently, this will not be covered by the warranty. Have the
chimney system cleaned by a professional sweeper.
6.3 Chimney Sweeping
Chimney sweeping can be difficult and dangerous. If you don’t have any experience sweeping
chimneys, you may want to hire a professional sweeper to inspect and clean your system the
first time. After seeing how the sweeping is done, you will know if it is a job you can do yourself.
The most commonly used equipment includes fiberglass rods with threaded connections and
plastic brushes. The brush is forcibly moved from top to bottom of the chimney to remove the
creosote by rubbing.
The chimney connector and its components should always be cleaned at the same time as the
chimney.
When the chimney is clean, open the access panel in front of the cookstove and remove the
accumulation of creosote and soot. Also clean accumulation inside the combustion chamber,
over the baffle.

PART B - INSTALLATION
7. General Information
7.1 Security
• Read this manual completely before installing the cookstove. It is important to fully respect the
installation instructions. If the cookstove is not correctly installed, it could result in a fire, bodily
injuries or even death.
• The information given on the certification label affixed to the appliance always overrides the
information published, in any other media (owner’s manual, catalogues, flyers, magazines and web
sites).
• Mixing of appliance components from different sources or modifying components may result in
hazardous condtions. Where any such changes are planned, Stove Builder International Inc. Should
be contacted in advance. Any modification of the appliance that has not been approved in writing
by the testing authority violates CSA B365 (Canada), and ANSI NFPA 211 (USA).
ENGLISH
• DO NOT CONNECT TO OR USE IN CONJUNCTION WITH ANY AIR DISTRIBUTION
DUCTWORK UNLESS SPECIFICALLY APPROVED FOR SUCH INSTALLATION.
• DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
• Connect this stove only to a listed factory-built chimney for use with solid fuel or to a lined masonry
chimney conforming to local and national building codes.
• If required, a supply of combustion air shall be provided to the room.
• Do not use makeshift materials or make any compromises when installing this cookstove.
• DO NOT INSTALL IN A MOBILE HOME.
7.2 Regulations Governing the Installation of the Cookstove
In Canada, the CSA B365 Installation Code for Solid Fuel Burning Appliances and Equipment
is to be followed in the absence of local code requirements. In the USA, the ANSI NFPA 211
Standard for Chimneys, Fireplaces, Vents and Solid Fuel-Burning Appliances is to be followed
in the absence of local code requirements.
This cookstove must be connected to a chimney complying with the requirements for Type HT
chimneys in the Standard for Factory-Built Chimneys for Residential Type and Building Heating
Appliances, UL 103 HT and ULC S627 or to a code-approved masonry chimney with a flue liner.
7.3 Cookstove Positioning
Choose a location to avoid the chimney conflicting with floor joists, roof trusses, wall studs,
water pipes, electric wires, and that allows the least possible deviations in the chimney. The
location of the cookstove must allow enough room for its maintenance and the exhaust system.
This cookstove weighs approximately 150 kg (330 lb). To validate the installation of additional
floor joist, consult the local building code.
Page 18
Installation and operation manual - Atlas woodburning cookstove
7.4 Location of the Certification Label
Since the information given on the certification label affixed to the appliance always overrides
the information published, in any other media (owner’s manual, catalogues, flyers, magazines
and web sites) it is important to refer to it in order to have a safe and compliant installation. In
addition, important information about the stove can be found (model, serial number, etc.). The
certification label is located on the back of the stove.
It is recommended to note the stove serial number on page 5 of this manual since it will
be needed to precisely identify the version of the appliance in the event replacement parts or
technical assistance is required. It is also recommended to register the warranty online.
8. Clearances to Combustible Materials
The clearances given in this section have been established following test results in accordance
with the procedures described in the standards ULC S627 (Canada) and UL 1482 (USA). When
this cookstove is installed respecting the indicated minimum clearances or more, the flammable
surfaces won’t overheat during normal or even abnormal usage.
None of the cookstove parts or smoke pipe can be installed closer to the combustible
materials than the minimum clearances indicated.
ENGLISH
Fuel, solid or liquid, should not be located closer to combustibles than the minimum
clearances given.
The clearances to the combustible walls can differ slightly between Canada and the United
States and can also vary depending on the use of a single wall or double connector. Make sure
to use the proper clearances for the location and the type of pipe.
The clearances of the appliance and the flue pipes must be met individually, meaning the
appliance can not be installed closer to the combustible materials than the single or double wall
pipe allows. Refer to the following images and tables for minimum required clearances

Floor Protection
This cookstove is designed to prevent the floor from overheating. However, it must be placed on
a non-flammable surface to protect the floor from hot embers that may fall during loading. The
floor protection must be a continuous non-combustible surface such as steel with a minimum
thickness of 0.015" (0.38 mm), ceramic, concrete board, brick or other equivalent approved
material. Ceramic should be placed on a continuous non-combustible board to prevent contact
between the cinder and the floor through cracks or gaps in the ceramic grout. See the local code
for approved alternatives. No protection is required if the unit is installed on a non-combustible
surface (eg concrete floor) See table and figure below.

8.1 Clearances Reduction to the Walls and the Ceiling
It is often desired to use as little space as possible when installing cookstove. To do this, it
is possible to reduce the clearances safely and install the cookstove closer to the walls by
permanently installing a heat shield between the cookstove and the flammable material. Two
different heat shields , AC02710 and AC02784, are available to reduce clearances easily and
safely.
It is also possible to fabricate the heat shield but one must be careful since the rules for
heat shield construction are sometimes complicated. Read and apply the instructions carefully.
Some regions may have different regulations. Consult the local building code or contact the fire
department for restrictions, inspection and installation requirements in the area.
8.1.1 Heat Shield Construction Rules
• Adhesives used in the shield construction must not inflame or loose their adhesive properties at the
temperature that potentially will be reached.
• The assembly hardware must allow for complete vertical ventilation.
• The assembly hardware that penetrates in the combustible material from the screen surface can
only be used on the edges of the screen.

In Canada, the oor protection is limited to the back clearance (G) if it is less than 8" (203 mm). In the United States, it is only required under the
connected horizontal section and must exceed at least 2" (51 mm) on each side of the connection.

9. The Exhaust System
9.1 General Information
The exhaust system, consisting of the chimney and the pipe that connects the cookstove to the
chimney, acts as the engine that drives the wood heating system. Even the best appliance will
not work as securely and adequately as expected if it is not connected to an adequate chimney.
The heat contained in the exhaust gas, which goes from the cookstove to the chimney connector,
then to the chimney, is not lost heat. The chimney uses that heat to create the draft that draws
the combustion air, keeps the smoke in the appliance and evacuates the gas securely toward
open air. You can consider the heat contained in the exhaust gas as the combustible that the
chimney uses to create the draft.
9.2 Suitable Chimneys
To be suitable, a prefabricated metal chimney must follow the standards UL 103 HT (USA) or
ULC S629 (Canada). Furthermore, this wood burning cookstove has a performance and optimal
efficiency when it is connected to a 6" chimney flue.
9.2.1 Prefabricated Metal Chimney
ENGLISH
These are sometimes referred to as "high temp"
chimneys because they have the specific characteristics
to withstand the temperatures that can be created by
wood burning stoves. Factory-built chimneys are tested
as a system with all the necessary components for
installation. The instructions provided with the chimney
by its manufacturer are the only reliable source of
installation guidelines. To be safe and effective, the
chimney must be installed exactly in accordance with
the manufacturer’s instructions. Only components
intended for the brand and model of chimney shoud
be used. Never fabricate or substitute parts from other
chimney brands. The chimney must be a type suitable
for solid fuel.
Installation and operation manual - Atlas woodburning cookstove
Page 25
9.2.2 Masonry Chimney
The cookstove may also be connected to a masonry
chimney, provided the chimney complies with the
construction rules found in the building code enforced
locally. The chimney must have either a clay liner or
a suitably listed stainless steel liner. If the masonry
chimney has a square or rectangular liner that is
larger in cross sectional area than a round 6" flue, it
should be relined with a suitably listed 6" stainless
steel liner. Do not downsize the flue to less than 6"
unless the venting system is straight and exceeds 25
feet in height. When passing through a combustible
wall, the use of an insulated listed thimble is required.
ENGLISH
9.3 Chimney Height
The chimney top must be high enough to overcome air turbulence caused by the wind blowing
around the house and over the roof. The chimney must exceed by at least 1 meter (3 ft.) its
highest exit point from the roof and by at least 60 cm (2 ft.) for any part of the roof or any
obstacle located at a horizontal distance of at least 3 m (10 ft.).
Page 26
Installation and operation manual - Atlas woodburning cookstove
10. Combustion Air Supply
For the cookstove draft to work correctly, the room must have an outside or fresh air inlet, with
a minimum of 4" diameter, from the house exterior to the room, that is at least sufficient to
replenish the volume of air that comes out of the chimney flue. In well insulated houses an air
inlet must be fitted through the outer wall that is not exposed to the prevailing winds, depending
on the surrounding conditions of the house. If a vent is installed, it must be fitted in such a way
that it cannot be blocked.
The outdoor air must be routed through a duct no more than 300 mm (12") away from the
appliance, in order not to interfere with its operation. A watertight mechanical valve will close
the air inlet when the cookstove is not used. Protection against rodents must be installed on
external edge.
When the cookstove and the chimney are completely cold, it may be necessary before starting
up to provide an external air supply by opening a door or a window for a short period. A
house constructed or renovated in a waterproof manner is prone to not having the air exchange
required for the proper functioning of a wood heating appliance.
In that case, avoid, during startups, to use appliances that evacuate air outside of the house,
such as:
ENGLISH
• Cookstove hood
• Bathroom vent
• Air exchange system
The supply of fresh combustion air can be done in several ways, provided they comply with CSA
B365 and NFPA211.
• Ventilated central vacuum cleaner
• Dryer
11. Chimney Connector Installation
The chimney connector is the single or double wall pipe, installed between the cookstove and
the chimney. The components of the single wall pipe are sold in most hardware or construction
supply stores. These sections usually do not comply with a precise standard and are not certified.
Consequently, several rules found in the heating appliance installation codes are applied to the
installation of the single wall pipe.
The double wall chimney connectors have gone through testing and are certified. The rules
for double wall pipes are found in the manufacturer’s installation guide. These rules are very
different from the single wall pipes.
11.1 Single Wall Chimney Connector Installation
The entire chimney connector has been called "the weak link" in the security of the wood heating
system because if the connector is not properly installed, it can provoke a fire.
The best smoke pipe installation goes straight from the cookstove to the base of the chimney
with no elbow. Straight installation will cause fewer problems such as smoke returns when the
door is open to reload the appliance. They are also more stable and easier to maintain than
installations with elbows. Avoid, as much as possible, horizontal smoke pipes sections because
they reduce the chimney draft and are more conducive to creosote accumulation.

The rules below are based on the rules found in the installation code of a solid fuel burning
appliance. It is imperative to carefully follow these installation instructions or those of the local
code.
• An ideal pipe installation is the one that goes straight from the cookstove directly into the chimney,
without elbows. A straight installation requires either a telescopic section or a coupling pipe so it
can be mounted or dismounted without having to move the cookstove. A straight pipe installation
offers the minimum amount of restriction to the exhaust of the smoke and gives a better draft.
Straight installations also need less maintenance because there are no angles where creosote can
be deposited.
• The maximum length of the horizontal pipe is 3m (10 ft.) including the elbows.
• The minimum clearance in relation to combustible materials is : 450 mm (18"). The minimum
clearance can be reduced if an appropriate heat shield is installed. See the heat shield installation
instructions for more details.
• The pipe between the cookstove and the chimney must be as short and straight as possible. It is
often better to use two 45 elbows instead of one 90 elbow.
• The maximum number of 90 elbows is two.
• The maximum unsupported horizontal length is 1m (3 ft.)
• Galvanized smoke pipes must not be used because their coating vaporizes itself at high temperature
and produces dangerous gas. Use black smoke pipes.
• Flue pipes must have a thickness of at least 24 ga.
• Flue pipe connectors must overlap at least 30 mm (1 ¼")
• Each installation connector must be fixed with at least three screws.
Page 28
Installation and operation manual - Atlas woodburning cookstove
• The installation must be able to expand: the installation of elbows allow expansion; straight
installations must have a coupling pipe with an extremity without attachment or with a telescopic
section.
• Minimum upward slope toward the chimney: 20 mm/m (¼" per foot)
• One of the installation extremities must be firmly fixed to the cookstove nozzle with three metal
screws and the other extremity firmly fixed to the chimney.
• It must be possible to clean the pipes either by a manhole or by removing the pipes. The removal
of the pipes must not require moving the cookstove.
• The male parts of the pipe sections must be toward the appliance so the ashes and the condensation
stay inside the pipe.
• A chimney connector shall not pass through an attic or roof space, closet or similar concealed
space, or a floor, or ceilling. Where passage through a waII, or partition of combustible construction
is desired, the installation shall conform to CAN/CSA-B365, Installation Code for Solid-Fuel-Burning
Appliances and Equipment
• The chimney connector must be in good condition and kept clean.
