Page 9: Zone Heating And How To Make It Work For You
2.2 ZONE HEATING AND HOW TO MAKE IT WORK FOR YOU Your new Osburn 900 wood fire 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. -

Osburn 900 Installation and Operation Manual The pieces should be a consistent length, with a maximum of 25 mm (1”) variation from piece to piece. 3.2.4 PIECE SIZE Firewood dries more quickly when it is split. Large unsplit rounds can take years to dry enough to burn. -
Page 13: How To Dry Firewood
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 fires. The complaints usually involve a lack of heat and dirty door glass. -

Page 16: Lighting Fires
Osburn 900 Installation and Operation Manual 4.3 LIGHTING FIRES Each person who heats with wood develops their own favorite way to light fires. Whatever method you choose, your goal should be to get a hot fire burning quickly. A fire that starts fast produces less smoke and deposits less creosote in the flue system. -
Page 17: Two Parallel Logs
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. -
Page 18: Ash Removal
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. -
Page 19: Firing Each New Load Hot
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. -
Page 20: Building Different Fires For Different Needs
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 wood fire’s heat output to the heat demand. Your house will need far less heat in April than in July 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 wood fire down so much that the fire will be smoky and inefficient. - Page 21 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 WOOD FIRE MAINTENANCE Your new wood fire will give many years of reliable service if you use and maintain it correctly.

Page 23: Door Adjustment
Osburn 900 Installation and Operation Manual 5.1.2 DOOR ADJUSTMENT In order for your wood fire 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. -
Page 24: Replacing The Door Gasket
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. -
Page 25: Cleaning And Painting The Wood Fire
Osburn 900 Installation and Operation Manual 5.1.5 CLEANING AND PAINTING THE WOOD FIRE Do not attempt to clean or paint the wood fire 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 FLUE SYSTEM Flue system cleaning can be a difficult and dangerous job. don’t have experience cleaning flue systems, you might want to hire a professional flue system sweep to clean and inspect the system for the first time. -
Page 27: Part B - Installation
Osburn 900 Installation and Operation Manual PART B – INSTALLATION It is very important to position the wood fire as close as possible to the flue system, and in an area that will favour the most efficient heat distribution possible throughout the house. The wood fire must therefore be installed in the room where the most time is spent, and in the most spacious room possible. -

Page 29: Clearances To Heat-Sensitive Materials
Osburn 900 Installation and Operation Manual 7 CLEARANCES TO HEAT-SENSITIVE MATERIALS It is of outmost importance that the clearances to heat-sensitive materials be carefully maintained upon installation of the wood fire you have selected. Refer to the tables below. No part of the wood fire or flue may be located closer to combustibles than the minimum clearance figures given. -
Page 30: Floor Protector
Osburn 900 Installation and Operation Manual Clearances to heat-sensitive materials and floor protection 7.3 FLOOR PROTECTOR If the wood fire is to be installed on top of a combustible floor, it must be guarded by a non combustible material as shown on the dotted line area of the above figures.

Page 33: The Flue System
Osburn 900 Installation and Operation Manual 8 THE FLUE SYSTEM 8.1 GENERAL The flue system, made up of the flue system and the flue between the wood fire and the flue system, acts as the engine that drives your wood heating system. Even the best wood fire will not function safely and efficiently as intended if it is not connected to a suitable flue system. -
Page 34: Masonry Flue Systems
Osburn 900 Installation and Operation Manual 8.2.2 MASONRY FLUE SYSTEMS The wood fire may also be connected to a masonry flue system, provided the flue system complies with AS/NZS 2918 or with the construction rules found in the building code enforced locally. -
Page 35: Minimum Flue System Height
Osburn 900 Installation and Operation Manual 8.3 MINIMUM FLUE SYSTEM HEIGHT Flue heights and lengths from AS/NZS 2918:2001 The top of the flue system should be tall enough to be above the air turbulence caused when wind blows against the house and its roof. -
Page 36: The Relationship Between The Flue System And The House
Osburn 900 Installation and Operation Manual 8.4 THE RELATIONSHIP BETWEEN THE FLUE SYSTEM AND THE HOUSE Because the flue system is the engine that drives the wood heating system, it must have the right characteristics. The signs of bad system design are cold downdraught when there is no fire in the wood fire, slow kindling of new fires, and smoke roll-out when the door is opened for loading. -
Page 37: Why The Flue System Should Penetrate The Highest Heated Space
Osburn 900 Installation and Operation Manual 8.4.2 WHY THE FLUE SYSTEM 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. - Page 38 Osburn 900 Installation and Operation Manual Use 45° elbows where possible, instead of 90° elbows. 38 ______________________________________________________________________________...
