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 m easured 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.

You may decrease these 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. The installation standards
of such heat radiation shields are listed on the following page.
IT IS STRICTLY FORBIDDEN TO PLACE WOOD WITHIN MINIMUM CLEARANCES
TABLE 1.3 Clearances to combustible materials
For mobile home installation
• Outside air kit with a listed double wall connector(CAN: ULC S641; USA: UL103) and
listed compatible chimney system(CAN: ULC S629; USA: UL103HT)
• Use clearances from combustibles specified in the double wall connector installation.
CAUTION: The structural integrity of the mobile home floor, wall and ceiling/roof must be
maintained.

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 p ipes 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.
FIGURE 2.2 Minimum Height of the Chimney
2.2.1 Step by step installation of your factory-built chimney
The way to install your chimney may vary from one chimney manuf acturer 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)
