2.3 ZONE HEATING AND HOW TO MAKE IT WORK FOR YOU Your new Osburn 2400 wood stove 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.
2.4 THE BENEFITS OF LOW EMISSIONS AND HIGH EFFICIENCY The low smoke emissions produced by the special features inside the Osburn 2400 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.

Osburn 2400 Installation and Operation Manual 3.2.3 LOG LENGTH Logs should be cut about 1” (25 mm) shorter than the firebox so they fit in easily. Pieces that are even slightly too long make loading the stove very difficult. The most common standard length of firewood is 16”...
Osburn 2400 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.
Osburn 2400 Installation and Operation Manual 3.2.6 JUDGING FIREWOOD MOISTURE CONTENT You can find out if some firewood is dry enough to burn by using these guidelines: • cracks form at the ends of logs as they dry as it dries in the sun, the wood turns from white or cream coloured to grey or yellow, •...
Osburn 2400 Installation and Operation Manual 4 OPERATING YOUR STOVE 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 stove are conditioned. As the paint cures, some of the chemicals vaporize. The vapors are not poisonous, but they do smell bad.
Osburn 2400 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.
Osburn 2400 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.
Osburn 2400 Installation and Operation Manual 4.3.3 RAKING CHARCOAL Rekindle the fire when you notice that the room temperature has fallen. You will find most of the remaining charcoal at the back of the firebox, furthest from the door. Rake these coals towards the door before loading.
Osburn 2400 Installation and Operation Manual If the flames get small and almost disappear when you turn down the air, you have turned down the air too early, or your firewood is wetter than it should be. With good fuel and correct air control use, the flames should slow down, but should stay large and steady, even as the air supply is reduced.
Page 21
Osburn 2400 Installation and Operation Manual 4.3.6.4 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. The flaming phase of the fire lasts for roughly the first half of the burn cycle and the second half is the coal bed phase during which there is little or no flame.
Osburn 2400 Installation and Operation Manual 5 MAINTAINING YOUR WOOD HEATING SYSTEM 5.1 STOVE MAINTENANCE Your new stove 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.
Osburn 2400 Installation and Operation Manual 5.1.3 DOOR ADJUSTMENT In order for your stove to burn at its best efficiency, the door must provide a perfect seal with the firebox. Therefore, the gasket should be inspected periodically making sure to obtain an air tight fit.
Osburn 2400 Installation and Operation Manual 5.1.5 REPLACING THE GLASS GASKET AND/OR THE GLASS It is a good idea to replace the glass gasket when the door gasket is replaced. The gasket is flat, adhesive-backed, woven fibreglass. Remove the glass retaining screws (A) and metal frame (B) that holds the glass (D) to the door frame (E).
Osburn 2400 Installation and Operation Manual 5.1.6 CLEANING AND PAINTING THE STOVE Do not attempt to clean or paint the stove when the unit is hot. Painted surfaces can be wiped down with a damp cloth. Plated surfaces may be scratched by abrasive cleaners. To maintain the finish at its original brilliance, use only a damp soft cloth to clean plated surfaces.
Osburn 2400 Installation and Operation Manual 5.2.3 CLEANING THE CHIMNEY Chimney cleaning can be a difficult and dangerous job. don’t have experience cleaning chimneys, you might want to hire a professional chimney sweep to clean and inspect the system for the first time.

Osburn 2400 Installation and Operation Manual 8 THE VENTING SYSTEM 8.1 GENERAL The venting system, made up of the chimney and the connecting pipe between the stove and the chimney, acts as the engine that drives your wood heating system. Even the best stove will not function safely and efficiently as intended if it is not connected to a suitable chimney.
Osburn 2400 Installation and Operation Manual 8.2.2 FACTORY-BUILT METAL CHIMNEYS IN MOBILE HOMES For use in a mobile home, this stove is to be connected to a 6” in diameter double wall factory built chimney conforming to CAN/ULC-S629, Standards 650°C Factory-built chimney.
Osburn 2400 Installation and Operation Manual 8.2.3 MASONRY CHIMNEYS The stove 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.
Osburn 2400 Installation and Operation Manual 8.4 THE RELATIONSHIP BETWEEN THE CHIMNEY AND THE HOUSE Because the venting system is the engine that drives the wood heating system, it must have the right characteristics. The signs of bad system design are cold backdrafting when there is no fire in the stove, slow kindling of new fires, and smoke roll-out when the door is opened for loading.
Osburn 2400 Installation and Operation Manual 8.4.2 WHY THE CHIMNEY SHOULD PENETRATE THE HIGHEST HEATED SPACE When it is cold outside, the warm air in the house is buoyant so it tends to rise. This tendency of warm air to rise creates a slight pressure difference in the house. Called ‘stack effect’, it produces a slightly negative pressure low in the house (relative to outside) and a slightly positive pressure zone high in the house.
Only a wood stove certified and labelled as ‘mobile home approved’ may be installed in a mobile home. This Osburn 2400 stove is ‘mobile home approved’. Wood stoves installed in mobile homes must have a ducted supply of combustion air from outdoors. This air supply should be routed down through the house floor into the vented crawl space under the mobile home.
Osburn 2400 Installation and Operation Manual 8.6.1 INSTALLATION OF SINGLE WALL CHIMNEY CONNECTOR The chimney connector assembly has been called ‘the weak link’ in the safety of wood heating systems because failure to install the connector properly (which has been common in the past) can result in house fires.
Page 42
Osburn 2400 Installation and Operation Manual The rules below are based on those found in the CSA B365 installation code. Please carefully follow these installation instruction rules, or those enforced where you live. Maximum overall length of straight pipe: 3 m (10 ft.) including elbows.
Osburn 2400 Installation and Operation Manual APPENDIX 1: INSTALLING THE OPTIONAL DOOR OVERLAY In order to complete the assembly of your wood stove, you need to install the door overlay. See figure below for installation instructions: Position the overlay (A) on the door frame and secure it from inside the door using the 4 included screws (B).
Osburn 2400 Installation and Operation Manual APPENDIX 2: INSTALLING THE OPTIONAL FRESH AIR INTAKE KIT (OA10500/AC02090) When installed with a fresh air kit, the stove must be anchored to the floor. This mobile home approved stove requires installation of a fresh air intake kit (A) and an insulated fresh air intake pipe (B), sold separately.
Osburn 2400 Installation and Operation Manual APPENDIX 3: INSTALLATION AND USE OF THE OPTIONAL BLOWER (OA10510) An optional blower can be installed on the back of the stove to increase the flow of air past heat exchange surfaces and to help circulate warm air in the room. When used regularly, the blower can provide a small increase in efficiency, up to 2 percent.
Page 46
Osburn 2400 Installation and Operation Manual The blower has a rheostat, see the illustration on the right to identify the different adjustment positions; either from high (HI) to low (LO) or closed (OFF). When using the optional blower, allow the stove to reach operating temperature (approximately one hour), before turning it on.
