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.
1.3 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.
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.

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.
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.
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.
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 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.
Stove pipe • An adequate number of stove pipe sections. • A 90o elbow Typical installation through the wall FIGURE 2.2.
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.
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.
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.
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.
Typical installation through the ceiling FIGURE 2.2.
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.
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.
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.
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.

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.
FIGURE 2.
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.
In order to prepare your stove for the connection to a fresh air kit, please follow the following steps. (only available with FW2470 model) 1- Remove the back pedestal shield. Using pliers, remove ring (A) as shown below. Ring (A) is a small piece of metal held by micro joints located inside the 3” (76mm) spigot on the middle of the back pedestal shield. 2- Put the back pedestal shield in place using the 4 screws. 3- Connect a flexible insulated pipe to the 3” (76mm) spigot on the back pedestal shield.
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.
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 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.
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.
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.
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.
Increase air Decrease air Air control adjustment for model FW2470 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.
For the FW700 and the FW3000 model, we suggest that you operate it with the air control slightly open (approximately 10%) to achieve an optimum efficiency. Make sure that you have a good fire going and an adequate ember bed before you completely close the air control. Use a chimney thermometer if necessary. Closing the air control too soon will lower combustion efficiency and may cause the fire to die out.
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.
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.
• 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.
