CW2500 Insert Installation and Operation Manual 2.2 Zone Heating and How to Make it Work for You Your new CB2500 wood insert is a space heater, which means it is intended to heat the area it is installed in, as well as spaces that connect to that area, although to a lower temperature. This is called zone heating and it is an increasingly popular way to heat homes or spaces within homes.
CW2500 Insert Installation and Operation Manual 2.3 The Benefits of Low Emissions and High Efficiency The low smoke emissions produced by the special features inside the CB2500 firebox mean that your household will release up to 90 percent less smoke into the outside environment than if you used an older conventional stove. But there is more to the emission control technologies than protecting the environment.
CW2500 Insert Installation and Operation Manual 3 Fuel 3.1 Materials That Should Not be Burned • 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, • LIQUIDS SUCH AS KEROSCENE OR DIESEL FUEL TO START A FIRE. 3.2 How to Prepare or Buy Good Firewood 3.2.
CW2500 Insert Installation and Operation Manual 3.2.3 Log Length Logs should be cut at least 1” (25 mm) shorter than the firebox so they fit in easily. Pieces that are even slightly too long make loading the insert very difficult. The most common standard length of firewood is 16” (400 mm). The pieces should be a consistent length, with a maximum of 1” (25 mm) variation from piece to piece. 3.2.4 Piece Size Firewood dries more quickly when it is split.
CW2500 Insert Installation and Operation Manual 3.2.5 How to Dry Firewood Firewood that is not dry enough to burn is the cause of most complaints about wood inserts. Continually burning green or unseasoned wood produces more creosote and involves lack of heat and dirty glass door. See Section 5: Maintaining your wood heating system for concerns about creosote.
CW2500 Insert Installation and Operation Manual 3.2.
CW2500 Insert Installation and Operation Manual 4 Operating Your Insert 4.1 Your First Fires Two things will happen as you burn your first few fires; the paint cures and the internal components of the insert are conditioned. As the paint cures, some of the chemicals vaporize. The vapors are not poisonous, but they do smell bad. Fresh paint fumes can also cause false alarms in smoke detectors. So, when you first light your insert, be prepared by opening doors and/or windows to ventilate the house.
CW2500 Insert Installation and Operation Manual 4.2.2 The Top Down Fire The top down fire starting method solves two problems with the conventional method: first, it does not collapse and smother itself as it burns; and second, it is not necessary to build up the fire gradually because the firebox is loaded before the fire is lit. A top down fire can provide up to two hours of heating or more. The top down method only works properly if the wood is well-seasoned.
CW2500 Insert Installation and Operation Manual 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. Do not attempt to produce a steady heat output by placing a single log on the fire at regular intervals.
CW2500 Insert Installation and Operation Manual 4.3.4 Firing Each New Load Hot Place the new load of wood on and behind the charcoal, and not too close to the glass. Close the door and open the air control fully. Leave the air control fully open until the firebox is full of flames, the wood has charred to black and its edges are glowing red.
CW2500 Insert Installation and Operation Manual 4.4 Blower Operation Allow the insert to reach operating temperature (approximately one hour), before turning on the blower, since increased airflow from the blower will remove heat and affect the start-up combustion efficiency. NOTE: ENSURE THE BLOWER CORD IS NOT IN CONTACT WITH ANY SURFACE OF THE INSERT TO PREVENT ELECTRICAL SHOCK OR FIRE DAMAGE. DO NOT RUN CORD BENEATH THE INSERT.
CW2500 Insert Installation and Operation Manual You will need to be cautious when building fires like this because if the air is turned down too much, the fire could smoulder. Make sure the wood is flaming brightly before leaving the fire to burn. 4.4.1.4 Maximum Burn Cycle Times The burn cycle time is the period between loading wood on a coal bed and the consumption of that wood back to a coal bed of the same size.
CW2500 Insert Installation and Operation Manual 5 Maintaining Your Wood Heating System 5.1 Insert Maintenance Your new insert will give many years of reliable service if you use and maintain it correctly. Some of the internal components of the firebox, such as firebricks, baffles and air tubes, will wear over time under intense heat. You should always replace defective parts with original parts (see Appendix 4: Exploded Diagram and Parts List).
CW2500 Insert Installation and Operation Manual 5.1.3 Replacing the Door Gasket It is important to maintain the gasket in good condition. After a year or more of use, the door gasket will compress and become hard, which may allow air to leak past it. You can test the condition of the door gasket by closing and latching the door on a strip of paper. Test all around the door. If the paper slips out easily anywhere, it is time to replace the gasket.
CW2500 Insert Installation and Operation Manual Do not abuse the glass door by striking or slamming shut. Do not use the insert if the glass is broken. To change the glass, perform the same operation described above. 5.1.5 Cleaning and Painting the Insert Do not attempt to clean or paint the insert when the unit is hot. Painted surfaces can be wiped down with a damp cloth. Plated surfaces may be scratched by abrasive cleaners.
CW2500 Insert Installation and Operation Manual It is recommended to clean thoroughly the chimney system at the end of every heating season. During summer, the air is damper and with minimal air circulation within the stove or furnace, it can mix with creosote and/or sooth deposits in the chimney system to form an acid that could accelerate the corrosion process and induce premature decay of the steel. Corrosion damages are not covered under warranty.
CW2500 Insert Installation and Operation Manual PART B - INSTALLATION 6 Pre-Installation Masonry fireplace requirements The masonry fireplace must meet the minimum requirements found in the building code enforced locally, or the equivalent for a safe installation. Contact your local Building Inspector for requirements in your area. An inspection of the fireplace should include the following: 1.
CW2500 Insert Installation and Operation Manual 3. CHIMNEY CAPS: Mesh type chimney caps must have provision for regular cleaning, or the mesh should be removed to eliminate the potential of plugging. 4. ADJACENT COMBUSTIBLES: The fireplace should be inspected to make sure that there is adequate clearance to combustibles, both exposed combustibles to the top, side, and front as well as concealed combustibles, in the chimney and mantle area.

CW2500 Insert Installation and Operation Manual Non-combustible floor protection of at least 3" (76 mm) in depth must be installed in front of the fireplace hearth extension. If the extension of the masonry hearth is raised at least 8" (F) from the floor protection, a non-combustible material without an R factor extending 16 " (406 mm) (USA)/18’’ (457 mm) (CAN) from the front of the insert is required.
CW2500 Insert Installation and Operation Manual There are two ways to calculate the R factor of the floor protection. First, by adding the Rvalues of materials used, or by the conversion if the K factor and thickness of the floor protection are given. To calculate the total R factor from R factors of the materials used, simply add the Rvalues of materials. If the result is equal to or greater than the R-value requirements, the combination is acceptable.

CW2500 Insert Installation and Operation Manual 9 The Venting System 9.1 General The venting system, made up of the chimney and the liner inside the chimney, acts as the engine that drives your wood heating system. Even the best insert will not function safely and efficiently as intended if it is not connected to a suitable chimney and liner system. The heat in the flue gases that pass from the insert into the chimney is not waste heat.
CW2500 Insert Installation and Operation Manual 9.3 Suitable Chimneys Your wood insert will provide optimum efficiency and performance when connected to a 6inch diameter chimney liner. The connection to a chimney having a diameter of at least 5 inches (Canada only) is permitted, if it allows the proper venting of combustion gases and that such application is verified and authorized by a qualified installer. Otherwise, the diameter of the flue should be 6 inches.
CW2500 Insert Installation and Operation Manual ATTENTION INSTALLER: When positioning the unit in a fireplace opening prior to the flue installation, install the insert into the opening until the top lip of air jacket is flush with fireplace facing. If lag-bolts or anchors are to be used to secure the insert, the hole locations should be marked with the unit in place. Remove the insert and locate the anchors.
CW2500 Insert Installation and Operation Manual 9.5 Chimney liner installation 1) Using a power driver with a Robertson end, secure the elbow (A) on the liner which has been lowered into the chimney, using 3 self-piercing screws (B) included in the instruction manual kit. 2) Slide the insert into the fireplace opening. 3) Attach the other end of the elbow on the insert’s flue outlet.
CW2500 Insert Installation and Operation Manual 9.6 Minimum Height Chimney The top of the chimney should be tall enough to be above the air turbulence caused when wind blows against the house and its roof. The chimney must extend at least 1 m (3 ft.) above the highest point of contact with the roof, and at least 60 cm (2 ft.) higher than any roof line or obstacle within a horizontal distance of 3 m (10 ft.). 9.
CW2500 Insert Installation and Operation Manual There are two reasons why the chimney in the house at right will cold backdraft when it is cold outside and there is no fire burning in the insert. First, the chimney runs up the outside of the house, so the air in it is colder and denser than the warm air in the house.
