  • Page 14: Zone Heating And How To Make It Work For You

    2.3 ZONE HEATING AND HOW TO MAKE IT WORK FOR YOU Your new Osburn Soho 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.
  • Page 15 Soho Installation and Operation Manual The C-Cast baffle is made of an aluminosilicate fibre material that is compressed with a binder to form a rigid board. C-Cast can withstand temperatures above 2,000 °F. It is not considered hazardous waste. Disposal at a landfill is recommended. Firebrick is mainly composed of silicon dioxide, also known as silica, an earth derived product.

    Soho 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”...

  • Page 20: Operating Your Stove

    Soho 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.
  • Page 21: The Top Down Fire

    Soho 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.
  • Page 22: Ash Removal

    Soho 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.
  • Page 23: Firing Each New Load Hot

    Soho 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.
  • Page 24: Building Different Fires For Different Needs

    Soho Installation and Operation Manual 4.3.6 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.
  • Page 25 Soho 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.

    Soho 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.
  • Page 27: Door Adjustment

    Soho 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.

After a year or more of use, the door gasket will compress and become hard, which may allow air to leak past it.
  • Page 32: Replacing The Glass Gasket And/Or The Glass

    Soho Installation and Operation Manual 5.1.4 REPLACING THE GLASS GASKET AND/OR THE GLASS It is a good idea to replace the glass gasket when the door gasket is replaced.

  • Page 41: Reducing Wall And Ceiling Clearances Safely

    Soho Installation and Operation Manual 7.4 REDUCING WALL AND CEILING CLEARANCES SAFELY It is often desirable to reduce the minimum installation clearances by placing the stove closer to walls so the installation takes up less floor space. You can safely reduce the minimum clearances by permanently installing a shield between the stove and combustible material.

    Soho 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.

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...
  • Page 47: Why The Chimney Should Penetrate The Highest Heated Space

    Soho Installation and Operation Manual Good System Design Inferior System Design Inside chimneys are preferred because even when Outside chimneys are a problem because no fire is burning, there is normally upward flow in when no fire burns they will go into cold the system.
  • Page 48: Supply Of Combustion Air

    Soho 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.
  • Page 49: Air Supply In Conventional Houses

    Soho Installation and Operation Manual 8.5.2 AIR SUPPLY IN CONVENTIONAL HOUSES The safest and most reliable supply of combustion air for your wood stove is from the room in which it is installed. Room air is already preheated so it will not chill the fire, and its availability is not affected by wind pressures on the house.
