  • Page 12: Zone Heating And How To Make It Work For You

    Zone heating and how to make it work for you Your new Horizon wood fireplace 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 13: What Is Your New Fireplace Made Of

    2.6.1 What is your new fireplace made of? The body of your fireplace, which is most of its weight, is carbon steel. Should it ever become necessary many years in the future, almost the entire fireplace can be recycled into new products, thus eliminating the need to mine new materials.

  • Page 14: How To Prepare Or Buy Good Firewood

    3.1 How to prepare or buy good firewood 3.1.1 What is good firewood? Good firewood has been cut to the correct length for the fireplace, split to a range of sizes and stacked in the open until its moisture content is reduced to 15% to 20%. 3.1.2 Tree species The tree species the firewood is produced from is less important than its moisture content.

  • Page 15: Piece Size

    3.1.4 Piece size Firewood dries more quickly when it is split. Large unsplit rounds can take years to dry enough to burn. Even when dried, unsplit logs are difficult to ignite because they don’t have the sharp edges where the flames first catch.

  • Page 16: Judging Firewood Moisture Content

    3.1.6 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 colored to grey or yellow; •...

  • Page 17: Operating Your Fireplace

    4 OPERATING YOUR FIREPLACE This wood heater has a manufacturer-set minimum low burn rate that must not be altered. It is against federal regulations to alter this setting or otherwise operate this wood heater in a manner inconsistent with operating instructions in this manual. 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 fireplace are conditioned.

  • Page 18: Two Parallel Logs

    DO NOT LEAVE THE FIREPLACE UNATTENDED WHEN THE DOOR IS SLIGHTLY OPENED. ALWAYS CLOSE AND LATCH THE DOOR AFTER THE FIRE IGNITES. After the kindling fire has mostly burned, you can add standard firewood pieces until you have a fire of the right size for the conditions.

  • Page 19: Ash Removal

    4.3.2 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. The best time to remove ash is after an overnight fire when the fireplace is relatively cool, but there is still some chimney draft to draw the ash dust into the fireplace and prevent it from coming into the room.

  • Page 20: Shutting Down The Air Supply

    4.3.5 Shutting down the air supply The fireplace can operate at three different settings: Maximum combustion rate, medium combustion rate and finally low combustion rate. At the low combustion rate setting, the fireplace is operated with an air control system that regulates the combustion. The maximum combustion rate setting is usually for cold startup and when maximum heat is desired (Position A).
  • Page 21 In the B position, it is also possible to close the air supply manually if a power failure occurs by pushing the small lever to the left. HORIZON – Installation and Operation Manual...

  • Page 22: Building Different Fires For Different Needs

    4.3.6 Building different fires for different needs Using the air control is not the only way to match the fireplace’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 fireplace down so much that the fire will be smoky and inefficient.

  • Page 23: Maximum Burn Cycle Times

    4.3.8 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.

  • Page 24: Maintaining Your Wood Heating System

    5 MAINTAINING YOUR WOOD HEATING SYSTEM Fireplace maintenance Your new fireplace will give many years of reliable service if you use and maintain it correctly. Some of the internal components of the firebox, such as refractory slabs, baffles and air tubes, will wear over time under intense heat.

  • Page 25: Door Adjustment

    5.1.3 Door adjustment In order for your fireplace to burn at its best efficiency, the door must provide a perfect seal with the firebox. Therefore, the gasket should be inspected periodically to check for a good seal. The gasket seal may be improved with a simple latch mechanism adjustment.

  • Page 26: Door Alignment

    5.1.4 Door alignment To align, open the fireplace’s doors and loosen the pressures screws located on the lower and upper hinges of each door using a 3/32” Allen key to free the adjustable hinge rods. Using a flat screwdriver, turn the adjustable hinge rods in the direction shown to adjust the doors. Tighten all door hinge pressure screws when they are at the desired positions.

  • Page 27: Replacing The Door Gasket

    5.1.5 Replacing the door gasket It is important to maintain the gaskets in good condition. After a year or more of use, the door gaskets will compress and become hard, which may allow air to leak past it. You can test the condition of the door gaskets by closing and latching the door on a strip of paper.

  • Page 28: Replacing The Door Glass

    1400º F. If the glass breaks, it must be replaced with one having the same specification. Contact your Osburn dealer to obtain a genuine replacement part (see “replacement parts”, in appendix to get the proper part number).

  • Page 29: Cleaning And Painting The Fireplace

    5.1.6.1 Replacing the door glass gasket The gasket must be centred on the edge of the glass. To do this easily, peel back a section of the paper covering the adhesive and place the gasket on a table with the adhesive side up. Stick the end of the gasket to the middle of one edge, then press the edge of the glass down onto the gasket, taking care that it is perfectly centred on the gasket.

  • Page 30: How Often Should You Clean The Chimney

    5.2.2 How often should you clean the chimney? It is not possible to predict how much or how quickly creosote will form in your chimney. It is important, therefore, to check the build-up in your chimney monthly when getting used to the new fireplace until you determine the rate of creosote formation.

  • Page 31: Fire Baffle Removal Prior To Cleaning The Chimney

    The chimney should be swept following these steps: 1) Remove the fire baffle and air tubes. 2) Remove the rain cap. 3) Sweep the chimney. 4) Clean the inside of the firebox. 5) Re-install the baffle, the air tubes and the rain cap. CAUTION OPERATION OF YOUR HORIZON WITHOUT THE BAFFLE MAY CAUSE UNSAFE AND HAZARDOUS TEMPERATURE CONDITIONS AND WILL VOID THE WARRANTY.

  • Page 48: The Venting System

    7 THE VENTING SYSTEM General The venting system, acts as the engine that drives your wood heating system. Even the best fireplace will not function safely and efficiently as intended if it is not connected to a suitable chimney. The heat in the flue gases that pass from the fireplace into the chimney is not waste heat. This heat is what the chimney uses to make the draft that draws in combustion air, keeps smoke inside the fireplace and safely vents exhaust to outside.

  • Page 49: Chimney Installation Notes

    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 fireplace. 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.
