SECTION 1.0 INSTALLATION
When installed and operated as described in these instructions, the E.P.A Century wood stove is
suitable for use as a freestanding wood stove in residential installations. The E.P.A Century wood
stove is not intended for installation in a bedroom or a mobile home, except for the FW2470 model
In Canada, the CSA B365 Installation Code for Solid Fuel Burning Appliances and Equipment and
the CSA C22.1 Canadian National Electrical Code are to be followed in the absence of local code
requirements. In the USA, the ANSI NFPA 70 National Electrical Code and NFPA 211 Standard for
Chimneys, Fireplaces, Vents and Solid Fuel-Burning Appliances are to be followed in the absence of
local code requirements.
In addition to the national installation and/or local building codes, fire officials (or other authorities
having jurisdiction) should be contacted to determine what restrictions and installation requirements
might apply locally.
1.1 GENERAL INSTALLATION
CAUTION:
•
MIXING OF APPLIANCE OR FLUE SYSTEM COMPONENTS FROM DIFFERENT SOURCES OR MODIFYING THE
DIMENSIONAL SPECIFICATION OF COMPONENTS MAY RESULT IN HAZARDOUS CONDITIONS. WHERE SUCH
ACTION IS CONSIDERED, THE MANUFACTURER SHOULD BE CONSULTED IN THE FIRST INSTANCE.
• DO NOT CONNECT THIS UNIT TO ANY AIR DISTRIBUTION SYSTEM.
•
CRACKED AND BROKEN COMPONENTS, e.g. GLASS PANELS OR CERAMIC TILES, MAY RENDER THIS
INSTALLATION UNSAFE.
• A SOURCE OF FRESH AIR INTO THE ROOM OR SPACE HEATED SHALL BE PROVIDED WHEN REQUIRED.
• CONNECT THE STOVE ONLY TO A LINED MASONRY CHIMNEY CONFORMING TO NATIONAL AND LOCAL
BUILDING CODES FOR USE WITH SOLID FUEL, OR TO A LISTED FACTORY BUILT CHIMNEY SUITABLE FOR
USE WITH SOLID FUEL.
1.2 POSITIONING THE STOVE
It is very important to position the wood stove in an area that will favour the most efficient heat
distribution throughout the house. The stove should therefore be installed in the room where the
most time is spent, and in the most spacious room possible. Recall that wood stoves produce
radiating heat, the heat we feel when we are close to a wood stove. A wood stove also functions by
convection, that is through the displacement of hot air accelerated upwards and its replacement with
cooler air at the floor level. The stove’s convection effect is facilitated by the installation of a
blower.

1.3 CLEARANCES
Clearances to any combustibles when measured directly from the floor protector to the ceiling must
be a minimum of 84" (2134 mm). Clearances to any combustibles when measured directly from the
front of the stove must be a minimum of 48" (1219 mm). The stove must also be placed so as to
maintain the minimum clearances to combustible walls specified for each type of connector used.
See Table 1.3 below for all clearance measures. Refer to Figure 1.3 for a diagram of each of the
measures A through C.

1.3.1 Reduced clearances
You may decrease the clearances by installing heat radiation shields between the walls or
the ceiling and the stove. These heat radiation shields must be installed permanently, and
can include sheet metal, a rigid non-combustible sheet or a masonry wall.
Clearances of not less than 1" (25 mm) and not more than 3" (76 mm) between the bottom
of the shield and the floor and not less than 3" (76 mm) between the top of the shield and
the ceiling must be respected to allow vertical air circulation behind the shield. The shield
must extend 20" (500 mm) above the stove top and 18" (450mm) to each side of the stove
(see Graphic 1).
Following the installation of such a heat radiation shield, the clearances mentioned on the
stove certification plate may be reduced as stated in the following table.

1.4 FLOOR PROTECTOR
If the stove is to be installed on top of a combustible floor, it must be guarded by a non-combustible
material extending at least 18” (300mm) from the front and 8” (200mm) from the sides and the back
of the firebox., as shown in Figure 1.4 below.
Please note that a floor protection is required with the pedestal models for spark and ash shielding,
but not for limiting floor temperatures from the radiant heat of the stove. The stove was designed and
safety tested so that without any protection, the floor would not overheat.
Please refer to local building codes for suitable floor protection materials.

SECTION 2.0 CHIMNEY (FLUE SYSTEM)
2.1 DEFINITIONS
For clarity, the following definitions should be used with respect to these instructions:
• A chimney system consists of a connector off the top of the stove, and a chimney, which
attaches to the connector and terminates outside the house.
• A chimney can be a masonry chimney (of masonry construction with an inside liner), or a
factory built chimney.
• A factory built chimney can be a double wall chimney (two concentric pipes with insulation
- sometimes referred to as an insulated solid pack) or an air cooled chimney (three
concentric pipes, with insulation between the first and second pipes, and air between the
second and third pipes).
• A single wall connector is a single pipe.
• A double wall connector has two concentric pipes, no insulation, and is an air cooled
connector.
2.2 CHIMNEY
CAUTION:
• DO NOT fill any framed space around the factory-built chimney with insulation or any other
material. Insulation placed in this area could cause adjacent combustibles to overheat.
• Do not use makeshift compromises during installation as they may be safety hazards, and a
fire could result.
• Do not connect this unit to a chimney system serving another appliance.
• Do not cut rafters or ceiling joists without first consulting a building official to ensure
structural integrity is not compromised.
Your wood stove may be hooked up with a factory built or masonry chimney. If you are using a
factory built chimney, it must comply with UL103 (USA) or ULCS629 (Canada) standards. It must
therefore be a 6” (152mm) HT Type (2100°F) chimney. It is extremely important that it be installed
10

according to the manufacturer's specifications. The manufacturers’ installation instructions and
specified clearances should always be followed in accordance with local and national installation
codes. In Canada the CSA B365 and the CSA C22.1 installation codes are to be followed. In the
USA the ANSI NFPA 70 and ANSI NFPA 211 installation codes are to be followed.
If you are using a masonry chimney, it is important that it be built in compliance with the
specifications of the Building Code. It must be lined with fire clay bricks, or clay tiles, sealed
together with fire cement, or have a listed solid fuel burning stainless steel liner. Round chimneys
are the most efficient.
The interior diameter of the chimney should be identical to the stove's smoke exhaust. A chimney
which is too small may cause draft problems, since it may not have the required volume to properly
evacuate the quantity of smoke resulting from the combustion. A chimney whish is too large may
also cause draft problems. In fact, a large chimney will be harder to warm-up and may not reach high
enough temperatures to create a proper draft effect. Note that it is the chimney which creates the
draft effect, not your stove. Your stove's performance is therefore directly dependent on an
adequate draft from your chimney.
The following recommendations may be useful for the installation of your chimney:
• Do not connect your stove to a chimney serving another appliance.
• The chimney must rise above the roof at least 3' (0.9 mm) from the uppermost point of
contact. See Figure 2.2.
• The chimney must exceed any part of the building or other obstruction within a 10' (3.04 m)
distance by a height of at least 2' (0.6 m). See Figure 2.2.
• The minimum overall height of the chimney system, measured from the stove top to the
exterior termination cap of the chimney should be at least 12' (3.66m). A chimney which is
too short may lack the “tunnel effect” required to obtain a proper draft.
• Installation of an interior chimney is always preferable to an exterior chimney. Chimneys
constructed outside of the home on an exterior wall should be avoided if possible, especially
in colder climates. The gas which circulates into an interior chimney will cool more slowly,
thus reducing the build-up of creosote and the risk of flue fires.
• All else being equal, cooler chimneys will have less draft than hotter ones. This problem will
be amplified if the chimney is excessively long. A chimney which is excessively long may be
very hard to warm-up due to its higher volume. A cool chimney may even down draft
(reverse flow) due to the difficulty in heating it up to operating temperature while trying to
evacuate the stack gases.
•
If an exterior chimney is used, the best results will be obtained by using a connector
vertically off the unit to the highest possible point before elbowing off horizontally to the
exterior chimney. For efficiency and safety reasons the stove must not be installed with an
insulated chimney connected directly to the appliance.
• Using a fire screen at the extremity of the chimney requires regular inspection in order to
11

insure that it is not obstructed, thus blocking the draft. It should be cleaned when necessary.

2.2.1 Step by step installation of your factory-built chimney
The way to install your chimney may vary from one chimney manufacturer to another. The instructions
contained in this manual are based on the recommendations of chimney manufacturers whose products
are sold at many North American retailers of wood stoves and related heating accessories.
Wall support system
If your chimney must rise along an outside wall, you need to connect it to your stove through an
adjacent wall. For this type of installation, the following items are normally required :
Chimney
• Suitable lengths of chimney (enough to go up to your roof)
• An adjustable wall support
• A wall thimble
• An adequate number of wall bands (one for every 8 feet of chimney, excluding the roof portion)
• A stove pipe adapter
• One insulated tee & plug
• A roof flashing kit (if necessary)
• A chimney cap.
• Roof guys (if required)

Stove pipe
• An adequate number of stove pipe sections.
• A 90o elbow

1- Start by positioning your stove where you would like it to go, taking into account the minimum
clearances to combustible material. You will then be able to determine where the chimney will
pass through the wall. You will probably have to adjust the stove position slightly to ensure
that your chimney will run between the studs. You can use a stud finder to locate the studs. Use
a spoke saw or jig saw to cut a hole, remembering that you need to maintain a clearance of 2
inches between the chimney and any combustible materials. For concrete walls, cut a hole
slightly larger than the outer diameter of the chimney.
2- Once the opening completed, you need to frame in the area to allow for the installation of a wall
thimble. A wall thimble is not required for installations through concrete walls.
3- You must first secure the wall thimble into the exterior wall surface. Then, do the same inside
and fasten the trim plate.
14

4- Then, from outside the building, slide a short chimney length (attached to the tee) through the
wall thimble. The chimney must extend at least 3 inches into the living space where it attaches
to the stove pipe.
5- You can now install the wall support. Simply slide the wall support up to the tee, ensuring that
the adapter on the support engages with the female coupler on the bottom of the tee. When the
wall support is level and properly positioned, you can use lag bolts to secure it into the wall
studs. To complete the installation, install an insulated tee plug below the wall support.
15

6- You can start to add chimney sections. We recommend that you also use locking bands to
secure all connections. You will need to secure the chimney to the house using wall bands.
Wall bands wrap around the chimney and then attach to the wall. Install the first one 3 feet
above the wall support. Then, you will need another band for each 8 feet of chimney. Note: if
your chimney must be installed through your soffit, install a roof flashing above and
finishing plate below where the roof is cut. Consult the following section called “CEILING
SUPPORT SYSTEM” for more details.
7- Authorities require that the chimney extend not less than 3 feet above the highest point where it
passes through the roof of a building and not less than 2 feet above any portion of the building
within 10 feet. If the chimney extends more than 5 feet above the roof deck, roof guys with
telescoping legs and draw bands are required.
8- Finally, twist on your rain cap and you can head back inside.
16

9- You are now ready to connect your chimney to your stove. Simply install the inter-connecting
stove pipe between the stove pipe adapter and the stove. You can follow the instructions in the
following section (section 2.3) of this manual called « CHIMNEY CONNECTOR».
Ceiling support system
If your chimney must rise inside the house and go through the ceiling, you need to connect it to
your stove at the ceiling level. For this type of installation, the following items are normally
required :
Chimney
• An adequate number of chimney sections (enough to go up to your roof)
• A ceiling support kit with stove pipe adapter
• An attic insulation shield
• A roof flashing kit
• A chimney cap
• Roof guys (if necessary)
Stove pipe
• Suitable lengths of stove pipe

1. Place your stove where you would like it located and use a plumb line to mark the ceiling
directly above your stove flue. You will probably have to adjust this position slightly to ensure
that your chimney will run between the joists. You can use a stud finder to locate the joists. You
also need to take into account the minimum clearances to combustible materials. After you have
determined where the chimney will go through the ceiling, use a spoke saw or power jig saw to
cut a hole, remembering that you need a minimum 2-inch clearance between the chimney and
any combustible materials. Depending on whether you have a one or two story structure, you
will need to cut a matching hole through the floor of the attic or second floor living space.
2. Before you install the ceiling support, you need to frame the area.
3. To install the ceiling support, just slide the assembly into the framed opening from below.
Once you ensure that the finishing plate is flush with the underside of the ceiling and assembly
is level, secure it with screws.
19

4. Once the support is secure, you can begin to assemble the chimney by lowering the first section
into the support. Make sure that the male coupler is pointing upwards, as indicated by the
arrow on the chimney label.
5. Then, from beneath the support, insert the stove pipe adapter and twist-lock it into place.
6. Now, you can add additional chimney sections. Continue adding chimney lengths until a height
of about 2 feet below the next ceiling level. An attic insulation shield must be installed where a
chimney passes from a lower living space into an upper living space or attic space. It is
designed to keep insulation materials away from the chimney. A second attic insulation shield
must be installed if your chimney passes from a lower living space into an upper living space.
As wee, you must enclose all sections of the chimney where is passes through a living space.
Elbows (15o or 30o) are used when you need to offset your chimney to clear an obstruction or to
avoid having to cut joists.
20

7. Once you have cut through your roof and framed the joists, it is time to work outdoors.
Authorities require that the chimney extend not less than 3 feet above the highest point where it
passes through the roof of a building and not less that 2 feet above any portion of the building
within 10 feet. You will need to install a roof flashing. The roof flashing slides over your
chimney pipe and goes under your shingles. Once you have done that, check that everything is
plumb, and nail the flashing into the roof deck. Seal the joint between the shingles and the plate
with silicone.
8. Next, slide the storm collar down the chimney until it contacts the flashing. Tighten the nut and
bolt and seal the collar to the chimney with a waterproof, non-combustible silicone sealant.
Finally, twist on your rain cap and you can head back inside. If the chimney extends more than
5 feet above the roof deck, roof guys with telescoping legs and draw bands are required.

9. You are now ready to connect your chimney to your stove. Simply install the inter-connecting
stove pipe between the stove pipe adapter and the stove. You can follow the instructions in the
following section (section 2.3) of this manual called « CHIMNEY CONNECTOR».

2.2.2 Typical installation through an existing masonry chimney
You can also install your stove using your existing masonry chimney. To do so, follow the
guidelines below. You may want to use a factory-built thimble, on construct your own brick thimble.
If you are using a masonry chimney, it is important that it be built in compliance with the
specifications of the Building Code in your region. It must normally be lined with fire clay bricks,
metal or clay tiles sealed together with fire cement. (Round flues are the most efficient).

2.3 CHIMNEY CONNECTOR
Your chimney connector (commonly called stove pipe) and chimney must have the same
diameter as the stove’s exhaust outlet. The stove pipe must be made of aluminized or cold roll
steel with a minimum 24-gauge thickness (0.021" or 0.53 mm). It is strictly forbidden to use
galvanized steel.
The following recommendations may be useful for the installation of your chimney connector:
• Your chimney connector should be assembled in such a way that the male end (crimped)
faces down to prevent creosote dripping outside the joints. Attach each of the sections to one
another with three equidistant metal screws. Also use three equidistant metal screws to
attach the connector to the stove’s exhaust collar. See Figure 2.3 (A) and Figure 2.3 (B).
• The pipe must be short and straight. All sections installed horizontally must slope at least ¼
inch per foot, with the upper end of the section toward the chimney. See Figure 2.3 (B).
• To insure a good draft, the total horizontal length of the connector should never exceed 8' to
10' (2.4 to 3.04 m). In the case of vertical installation, the total length of the connector can
be much longer and connected without problem to the chimney at the ceiling level.
• There should never be more than two 90 degrees elbows in the whole connector and chimney
system. Never start with a 90o elbow. Always go up vertically for at least 2 feet from the flue
spigot before using a 90o elbow.
• The connector must not pass through any combustible material, nor may it pass through a
concealed space (such as an attic, roof space, or closet). If passing through a wall, ceiling, or
into a masonry chimney, use either chimney components listed for that specific use, or means
acceptable to local authorities having jurisdiction over the installation.
• Installation of a "barometric draft stabiliser" (fireplace register) on a connector is not
recommended.
• Furthermore, installation of a draft damper is prohibited. Indeed, with a controlled
combustion wood stove, the draft is regulated upon intake of the combustion air in the stove
and not at the exhaust.

2.4 DRAFT
Your E.P.A Century stove’s performance will be optimised if it is installed with a chimney (flue)
system that provides an adequate draft. The draft is the force that moves air from the appliance up
through the chimney and is predominantly affected by the height and diameter of the chimney, as
well as the stack temperatures of the stove. If you test the draft using a pressure gauge, the reading
should be between .05 - .07 inches of water column (w.c.) at a medium-high fire. A draft measure of
less than .03" w.c. will cause operational difficulties while too much draft (greater than .10" w.c.)
will result in over-firing of the stove. This can result in excessive operating temperatures. If this is
the case, a manual damper may be installed in the vertical chimney connector to help reduce
excessive draft.
2.5 OUTSIDE COMBUSTION AIR
It is recommended to install 3’’ (76mm) outside air intake in the room where the stove is located or
nearby.
The following are signs that a fresh air kit may be required:
• Your stove does not draw steadily, smoke rollouts occur, wood burns poorly, or back-draft
occurs whether or not there is combustion present.
• Existing fuel-fired equipment in the house, such as fireplaces or other heating appliances,
smell, do not operate properly, suffer smoke rollouts when opened, or back-draft occurs
whether or not there is combustion present.
• Opening a window slightly on a calm (windless) day alleviates any of the above symptoms.
• The house is equipped with a well-sealed vapour barrier and tight fitting windows and/or has
any powered devices that exhaust house air.

2.6 THE ADVANTAGE OF INSTALLING A BLOWER (FAN)
A blower can be installed at the back of your E.P.A Century stove. This option is necessary if you
wish to redistribute into a room the heat trapped at the back of your stove. By forcing hot air toward
the front, the blower enables you to extend the radiation and convection power of your stove. You
can purchase this option through your E.P.A Century dealer. Make sure you specify the correct part
number: AC02050. Installation instructions are supplied with the blower.

SECTION 3.0 OPERATION
Keep these instructions for future reference.
WARNING:
• ANY MODIFICATION OF THE APPLIANCE THAT HAS NOT BEEN APPROVED IN WRITING BY THE
TESTING AUTHORITY IS CONSIDERED AS BREACHING CSA B365 (CANADA), AND ANSI NFPA
211 (USA).
• NEVER MODIFY THE AIR INTAKE CONTROL.
• DO NOT USE FLAMMABLE LIQUIDS OR AEROSOLS TO START OR REKINDLE THE FIRE.
• DO NOT USE FLAMMABLE LIQUIDS OR AEROSOLS IN THE VICINITY OF THIS APPLIANCE WHEN IT IS
OPERATING.
• DO NOT STORE FUEL WITHIN HEATER INSTALLATION CLEARANCES.
• OPEN AIR CONTROL (AND DAMPER WHEN FITTED) BEFORE OPENING FIRING DOOR.
• THIS STOVE IS NOT DESIGNED TO BE USED WITH THE DOOR OPEN. THE DOOR MAY BE OPEN ONLY
DURING LIGHTING PROCEDURES. NEVER LEAVE THE STOVE UNATTENDED WHEN THE DOOR IS
OPEN.
• HOT WHILE IN OPERATION, KEEP CHILDREN, CLOTHING AND FURNITURE AWAY. CONTACT MAY
CAUSE SKIN BURNS. WEAR GLOVES TO OPERATE YOUR STOVE.
CAUTION
• THIS APPLIANCE SHOULD BE MAINTAINED AND OPERATED AT ALL TIMES IN ACCORDANCE WITH
THESE INSTRUCTIONS.
• THE USE OF SOME TYPES OF PRESERVATIVE-TREATED WOOD AS A FUEL CAN BE HAZARDOUS.
3.1 SAFETY INFORMATION
• These stoves are designed for safe operation WHEN BURNING WOOD ONLY. Altering or
modifying the unit or installation without proper authorisation will void the certification,
warranty, and safety listing, and may result in a safety hazard.
• For safety reasons, never leave the unit unattended with the door open or ajar. An open door,
and especially a door partially open or cracked, if left for longer than required for good
ignition can potentially result in unsafe chimney temperatures, and if left unattended, in hot
embers or ignited fuel falling out of the unit. Prolonged door open operation is not necessary
provided the unit has been properly installed and dry kindling is used to start the fire.

• Do not abuse the unit, either by over firing or by using wood or combustibles with salt
content, or harmful chemicals. Misuse is not covered by warranty.
• Even though your E.P.A Century has been specifically designed and tested to prevent smoke
spillage, always open the door slowly as this will minimise the likelihood of smoke spillage
or a back draft of flame or smoke into the room.
• Never use gasoline type lantern fuel, kerosene, solvents, charcoal lighter fluid, or
inflammable liquids to start or "refresh" a fire in the stove. Keep all such liquids well away
from the stove while it is in use.
• All stove surfaces become very hot during operation. Care is needed, especially with
children, to avoid contact with those surfaces.
• Do not elevate the fire by means of grates.
• CAUTION: DO NOT OVER FIRE THIS HEATER. Do not burn fuel in the stove at a rate higher than
that which will cause the ember bed level to exceed half the door opening height. We
strongly recommend that you purchase a chimney (flue) thermometer. There are two types
of thermometers: probe thermometers and magnetic thermometers (the later is also called
“stove top thermometer”). If you are using a probe thermometer, make sure that the
temperature does not exceed 900oF (482oC). If you are using a magnetic thermometer, make
sure that the temperature does not exceed 475oF (246oC). If the door handle of the stove
becomes excessively hot to the touch, consider this to be an indication of over firing. Over
firing can result in a safety hazard and can permanently damage the stove and chimney. This
damage is not covered by the warranty.
• Although the ceramic glass is extremely durable under any normal use, a few precautions are
required. Do not attempt to push logs further into the fire by using the door, as the glass may
break if any solid object heavily contacts it.
• Never operate the stove with the door open, or cracked slightly open, except briefly during
the lighting operation, and during refuelling. Leaving the door open continuously could
seriously overheat the chimney and adjacent combustibles. Do not operate the stove if there
is an abnormal air leakage into the stove, such as through deteriorated gaskets or cracked or
broken glass. Do not operate the stove without a door gasket. Leakage can result in
overheating, or in very airtight homes, could possibly cause smoking into the room. Smoke
may contain carbon monoxide, which is poisonous, and in sufficient quantities, is a health
hazard.

3.2 FUEL
Fuel for the stove must not be stored closer than the required clearances to combustibles (heat
sensitive materials). NEVER STORE WOOD IN THE ASH PAN COMPARTMENT.
Your E.P.A Century stove is designed to burn WOOD ONLY. Do not burn coal, charcoal, or trash in
the unit. Highly flammable items such as trash may ignite creosote in the chimney (flue), resulting in
a chimney fire. Never burn salt wood, beach wood, chemically treated wood, or wood removed from
salt water, since the deposits left will deteriorate the firebox. Damage caused by chemicals or salt is
not covered under warranty.
Seasoned cord wood is recommended. Wood should be air dried in a covered and ventilated area for
a minimum of six months (one year or more is recommended). This reduces the moisture content of
the wood, resulting in a better stove performance. Wood species with moisture content of 20% or
less are ideal. Dry, seasoned cord wood, can be distinguished from green wood by the cracks at each
end of the logs. Wet or green wood will tend to cause the fire to smoulder, producing large amounts
of creosote. Creosote buildup could result in a chimney fire. This wood will also prove difficult to
keep burning properly, and fires will tend to go out. Green wood produces very little heat, and
sometimes causes customers to think that the stove does not work.
Decayed wood or low-density wood has very little energy content or heating value, and will not burn
satisfactorily for long periods of time. An example of the energy values of some common wood fuels
found un North America is given in the following table:

3.2.1 The use of manufactured logs
There are numerous types of manufactured logs sold on the market. You must be very careful with
this type of product. Many brands of manufactured logs contain chemical additives. DO NOT
BURN ANY MANUFACTURED LOGS CONTAINING CHEMICAL ADDITIVES. If you do, you
may damage your stove and void the warranty. Logs containing chemical additives burn a lot hotter
and were designed for decorative fireplaces. Decorative fireplaces generally have larger, cooler, and
less air-tight fireboxes. Your E.P.A Century stove, on the other hand, has a smaller, completely
sealed firebox which attains much higher temperatures. It is therefore not designed to support
excessive heat caused by the addition of chemicals in manufactured logs. Manufactured logs made
of 100% wood residues do not cause any threat to your stove. You must however be careful.
Manufactured logs typically release a much larger heat output over a short period of time. Therefore,
you cannot place a large quantity of such logs into your stove, like you would with regular cord
wood. Start with one log, and gradually increase the load to 2 or 3 logs and see how your stove
reacts. Use a chimney (flue) thermometer and make sure that temperatures remain within the normal
operating range.
3.2.2 Simple wood moisture test
Add one large piece of wood to the top of an established fire. If it starts to burn on three sides within
one minute, it is dry and seasoned and right for burning. If it turns black and starts to burn in about
three minutes or more, it is damp. If it turns black and does not start burning until five minutes or
more, it is green and wet. If it hisses at any time, the wood is soaked and will not burn until the
excess of moisture is boiled away.
3.3 NOTES ABOUT FIRST FIRING
The fresh paint on your stove needs to be cured to preserve its quality. Once the fuel load is properly
ignited, only burn small fires in your stove for the first four hours of operation. Never open the air
control more than necessary to achieve a medium burn rate. Make sure that there is enough air
circulation while curing the stove. Open one or more windows. The odours can be smelled during
the 3 or 4 first fires. Never start your stove outside.

3.4 LIGHTING A FIRE
• Place enough crumpled balls of newspaper or other paper into the stove to cover the bottom
of the firebox.
• Place small and dry kindling on the crumpled paper.
• Place larger and dry kindling on top of the small kindling.
• Open the air intake control fully (see figures on next page).
• Light a fire at the bottom of the crumpled paper and close the door. If the fire tends to go out
momentarily, hold the door slightly ajar to activate the fire. As soon as the fire catches hold,
close the door.
• Ideally the large kindling should be burned until a thick bed of red embers is obtained. At
that point, add cord wood fuel and continue to operate the draft control wide open until the
fire is well established. Once the firebox is hot, the air control can be partially closed. After
30 minutes to one hour, you can close the air control completely. In order to have the best
indication of when you should close the air control completely to operate your stove the
most efficiently, use a chimney (flue) thermometer. If you are using a probe thermometer,
you can close the air control completely when the temperature on the thermometer reaches
900oF (482oC). If you are using a magnetic thermometer , you can close the air control
completely when the temperature on the thermometer reaches 475oF (246oC). Closing the air
control down too soon will lower combustion efficiency and may cause the fire to die out.
Over a period of time, it may also result in creosote build-up in the chimney (which could
lead a chimney fire).

3.5 MAINTAINING THE FIRE
Once the wood has been consumed (or partially consumed) and you have obtained a good bed of
embers, you should reload the unit. In order to do so, open the air control to its maximum for
approximately 15 seconds prior to opening the stove door. Then, proceed by opening the door very
slowly. Open it by 2” to 4” (52 to 104 mm) for 10 to 15 seconds before opening it completely. This
procedure will increase the draft and thus eliminate the smoke which is stagnant in a state of slow
combustion in the stove. Then, bring the red embers to the front of the stove and reload the unit.
Depending on the type of wood you burn and the strength of the draft in your flue, you may
have to leave the air control open to its maximum for more than 15 seconds to avoid smoke
spillage before you reload the stove.
Your E.P.A Century stove will work best if a thick bed of hot embers is maintained in the bottom of
the firebox, and a minimum of two large pieces of seasoned fuel are added. Combustion efficiency is
largely related to establishing a hot ember bed, and hot firebox temperatures. The quicker the stove
and chimney (flue) get up to normal operating temperatures, the better. A small intense fire is
preferred to a large smouldering fire, both to improve combustion efficiency and to reduce the
amount of creosote build-up. The best performance will be obtained by adding relatively small
amounts of fuel to a well established ember bed, and then operating with the air inlet control open
long enough to achieve a hot fire. The wood should be placed with air in between individual pieces.
Use a poker to make an air channel in the embers below the wood. This will allow air to flow under
the wood for a more efficient burn.
3.6 FAN (BLOWER) OPERATION
If you have purchased and installed and optional fan (blower), allow the stove to reach operating
temperature (approximately one hour), before turning on the fan. The increased airflow from the fan
will cool the firebox and affect the start-up combustion efficiency if the fan is turned on too quick.
CAUTION: ENSURE THAT THE FAN’S POWER CORD IS NOT IN CONTACT WITH ANY SURFACE OF THE TTOVE
TO PREVENT ELECTRICAL SHOCK OR FIRE DAMAGE. DO NOT RUN THE POWER CORD BENEATH THE STOVE.

SECTION 4.0 MAINTENANCE
4.1 CLEANING AND PAINTING YOUR STOVE
Clean the stove frequently so that soot, ash, and creosote do not accumulate. Do not attempt
to clean the stove when the unit is hot. Special care must be taken with gold plated surfaces
in order to maintain the finish at its original brilliance. Do not use an abrasive cleaner which
will scratch the paint or plated finish. Use only a soft and clean damp cloth.
If the paint becomes scratched or damaged, it is possible to give your wood stove a brand
new look, by repainting it with a 650oC heat resistant paint. For this purpose, simply scrub
the surface to be repainted with fine sand paper, clean it properly, and apply thin coats (2) of
paint successively. To retrieve the original finish, use the paint supplied by the manufacturer.
4.2 GLASS
• Inspect the glass regularly in order to detect any cracks. If you spot one, turn the stove off
immediately. Do not use the stove if the glass is broken.
• Do not close the glass door by sticking or slamming shot. Do not use the stove if the glass is
broken.
• If the glass on your stove breaks, replace only with a ROBAX® glass 5mm thick supplied by your
E.P.A Century dealer. Never use a substitute material.
• To replace the glass, remove the screws retaining the glass retainers inside the door. Remove the
mouldings and replace the damaged piece with a new one. Perform the procedure backwards
after replacing. When replacing the glass, you should change the glass gasket to make sure you
keep it sealed.
• Never wash the glass with a product that may scratch it. Use a specialized product, available in
the stores where wood stoves are sold. Only wash when the stove is cold.
• Under normal operating conditions, the glass is designed to stay clean. Glass cleaning may be
required when burning damp wood. Furthermore, small creosote or soot accumulation may occur
in the lower end corners of the glass when burning the stove with the air control at the minimum
setting. This is normal. The glass will clean itself when burning a hot fire during one hour or
more with the air control at its maximum setting. Nevertheless, cleaning the glass on a regular
basis is recommended to prevent thicker creosote or soot accumulation that can be very hard to
remove.

4.3 GASKETING
It is recommended that you change the door gasket (which makes your stove door air tight) once a
year, in order to insure good control over the combustion, maximum efficiency and security. To
change the door gasket, simply remove the damaged one. Carefully clean the gasket groove, apply a
high temperature silicone sold for this purpose, and install the new gasket. Use only the genuine
Century gasket. You may light up your stove again approximately 24 hours after having completed
this operation.
4.4 ASH REMOVAL USING THE ASH DRAWER
CAUTION: ASHES CAN START FIRES, EVEN AFTER SEVERAL DAYS OF INACTIVITY. NEVER DISPOSE OF ASHES
IN A COMBUSTIBLE CONTAINER. REMOVE ASHES WHEN THE STOVE AND ASHES ARE COLD.
Whenever the ashes get 3 – 4” (76 – 102 mm) deep in the firebox, they should be emptied into the
ash drawer, using the following instructions:
• Make sure the fire is out, and the stove is cold.
• Lift the ash dump plug in the center of the firebox by hooking the poker through the loop
on the cover and lifting up.
• Push the ashes through the hole and leave an ash bed of approximately 1” deep on the
firebox bottom to help maintain a hot ember bed.
• Clear the ashes from the area where the ash dump plug normally sits so that it will
properly seat against the opening edges. Tap it down with your poker to ensure proper
seating.
• Ashes should be placed in a metal container with a tightly fitting lid. This closed container
should be placed on a non-combustible floor or on the ground, well away from all
combustible (heat sensitive) materials, pending final disposal.
• Cover the ash dump plug with the remaining ashes and continue operation of your stove as
usual.
• If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be
retained in the closed container until all cinders have thoroughly cooled. Do not place other
waste materials in the metal ash container.
39

• If bright embers are glowing above the ash dump cap during a low or medium fire, air may be
leaking past the ash plug. If this is happening, a possible over fire hazard exists. The stove
should be shut down and allowed to cool. Properly seal the ash dump cap.
4.5 CHIMNEY (FLUE) CLEANING
Regular chimney (flue) maintenance, as well as good burning practices, are required to prevent
chimney fires. When wood (especially green wood) is burned without adequate heat or air supply, it
produces tar and other organic vapours (smoke), which combine with expelled moisture to form
creosote. The creosote vapours condense in the relatively cool chimney of a slow-burning fire. As a
result, creosote residues accumulate on the chimney. When ignited, this creosote makes an
extremely hot fire which could be hazardous. Your E.P.A Century stove has been designed to reduce
the amount of creosote produced. Even so, the chimney and any chimney connector should be
inspected at least once every two months during the heating season to determine if a creosote
build-up has occurred. If creosote has accumulated, it should be removed to reduce the risk of a
chimney fire. Call a professional chimney sweep, or go to your local E.P.A Century dealer, purchase
a chimney brush, and have the chimney cleaned. The chimney and chimney connector must be in
good condition and kept clean.
Contact your local, municipal, state, or provincial fire authority for information on how to handle a
chimney fire before there is any chance that it may happen.
