2.3 ZONE HEATING AND HOW TO MAKE IT WORK FOR YOU Your new Osburn 900 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 900 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 900 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 900 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 900 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 900 Installation and Operation Manual 4 OPERATING YOUR STOVE 4.1 THE USE OF A FIRE SCREEN. This stove has been tested for use with an open door in conjunction with a fire screen (AC01318, sold separately). Make sure the fire screen is properly secured on the stove to avoid any risk of fire.
Osburn 900 Installation and Operation Manual 4.3.1 CONVENTIONAL FIRE STARTING The conventional way to build a wood fire is to bunch up 5 to 10 sheets of plain newspaper and place them in the firebox. Next, place 10 or so pieces of fine kindling on the newspaper.
Osburn 900 Installation and Operation Manual 4.3.3 TWO PARALLEL LOGS Place two spit logs in the firebox. Place a few sheets of twisted newspaper between the logs. Now place some fine kindling across the two logs and some larger kindling across those, log cabin style.
Osburn 900 Installation and Operation Manual 4.4.2 ASH REMOVAL Ash should be removed from the firebox every two or three days of full time heating. Do not let the ash build up in the firebox because it will interfere with proper fire management.
Osburn 900 Installation and Operation Manual 4.4.4 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.
Osburn 900 Installation and Operation Manual 4.4.6 BUILDING DIFFERENT FIRES FOR DIFFERENT NEEDS Using the air control is not the only way to match the stove’s heat output to the heat demand. Your house will need far less heat in October than in January to be kept at a comfortable temperature. If you fill the firebox full in fall weather, you will either overheat the space or turn the stove down so much that the fire will be smoky and inefficient.
Page 22
Osburn 900 Installation and Operation Manual 4.4.6.4 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 900 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 900 Installation and Operation Manual 5.1.2 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 900 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.
Osburn 900 Installation and Operation Manual 5.1.5 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 900 Installation and Operation Manual 5.2.3 CLEANING THE CHIMNEY Chimney cleaning can be a difficult and dangerous job. If you 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. After having seen the cleaning process, you can decide if it is a job you would like to take on.
6.2 REGULATIONS COVERING STOVE INSTALLATION When installed and operated as described in these instructions, the Osburn 900 wood stove is suitable for use as a freestanding heater in residential installations. The Osburn 900 wood stove is not recommended for installation in a sleeping room.
ULC S627 (Canada), UL1482 (U.S.A.) and UL737 (U.S.A.). When the stove is installed so that its surfaces are at or beyond the minimum clearances specified, combustible surfaces will not overheat under normal and even abnormal operating conditions.
Osburn 900 Installation and Operation Manual 7.2 CLEARANCES TO WALLS AND CEILING The clearances to combustible walls may be slightly different in Canada and the U.S.A. and may also differ depending on whether you use single or double wall flue pipe. Please be sure to choose the correct clearance for your location and type of flue pipe.

Osburn 900 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 900 Installation and Operation Manual 8.2.2 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 900 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 900 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 stove. 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.
Osburn 900 Installation and Operation Manual 8.6 INSTALLING THE CHIMNEY CONNECTOR The chimney connector is the single or double wall pipe installed between the stove flue collar and the chimney breech. Single wall pipe components are available from most hardware and building supply stores.

Osburn 900 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 900 Installation and Operation Manual APPENDIX 1: INSTALLING THE OPTIONAL FRESH AIR INTAKE KIT (AC01331) When installed with a fresh air intake kit, the stove must be anchored to the floor. The installation instructions are provided with the Fresh Air Intake Kit (AC01331), sold separately.

Page 46
Osburn 900 Installation and Operation Manual APPENDIX 3: INSTALLATION AND USE OF THE OPTIONAL BLOWER AND THERMODISC 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 47
Osburn 900 Installation and Operation Manual When using the optional blower, allow the stove to reach operating temperature (approximately one hour), before turning it on. The increased airflow from the blower cools the firebox and could affect the start-up combustion efficiency if the blower is turned on too early. You can also install a thermodisc to enable the blower to start or stop automatically when the stove is hot or too cold.
