  • Page 13: Materials

    Materials The body of this 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. The paint coating on the fireplace is very thin.

  • Page 14: Emissions And Efficiency

    The success of zone heating will depend on several factors, including the correct sizing and location of the fireplace, the size, layout and age of your home and your climate zone. Three- season vacation homes can usually be heated with smaller fireplaces than houses that are heated all winter.

  • Page 15: Log Length

    Homeowners with access to both hardwood and softwood use both types for different purposes. Softer woods make good fuel for mild weather in spring and fall because they light quickly and produce less heat. Softwoods are not as dense as hardwoods so a given volume of wood contains less energy. Using softwoods avoids overheating the house, which can be a common problem with wood heating in moderate weather.

  • Page 16: Drying Time

    Drying Time Firewood that is not dry enough to burn is the cause of most complaints about wood-burning appliances. Continually burning green or unseasoned wood produces more creosote and involves lack of heat and dirty glass doors. Firewood with a moisture content between 15% and 20% will allow the fireplace to produce its highest possible efficiency.

  • Page 17: Operating The Fireplace

    4. Operating the 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.

  • Page 18: Burning Wood Efficiently

    5. Burning Wood Efficiently First Use Two things happen when burning the first few fires; the paint cures and the internal components are conditioned. As the paint cures, some of the chemicals vaporize. The vapors are not poisonous, but they smell bad. Fresh paint fumes can also trigger false alarms in smoke detectors. When lighting the heater for the first few times, it may be wise to open doors and windows to ventilate the house.

  • Page 19: Combustion Cycles

    Use four or five sheets of paper tied together and put them on top and around the kindling. Open the air intake control completely, ignite the paper and close the door. The top down fire method has two advantages over the traditional method: first, the fire does not collapse on itself, and it is not necessary to add wood gradually since the combustion chamber is full before the fire is lit.

  • Page 20: Rekindling A Fire

    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. Trying to produce a steady heat output by placing a single log on the fire at regular intervals is not recommended.

  • Page 21: Air Intake Control

    The best time to remove ash is in the morning, after an overnight fire when the fireplace is relatively cold, but there is still a little chimney draft to draw the ash dust into the fireplace and prevent going out into the room. Ashes should be placed in a tightly covered metal container.
  • Page 22 Here are some suggestions for building fires suitable for different heating needs. 5.7.1 Flash Fire To build a small fire that will produce a low heat output, use small pieces of firewood and load them crisscross in the firebox. The pieces should only be 3" (76 mm) to 4" (102 mm) in diameter. After raking the coals, lay two pieces parallel to each other diagonally in the firebox and lay two more across them in the other direction.

  • Page 23: Maintenance

    A longer burning time is not necessarily an indication of efficient fireplace operation. It is preferable to build a smaller fire that will provide three or four hours of heating than to fully load the firebox for a much longer burn. Shorter burn cycles make it easier to match the heat output of the fireplace to the heat demand for the space.

  • Page 24: Glass Door

    Glass Door 6.3.1 Cleaning Under normal conditions, the door glass should stay relatively clear. If the firewood is dry enough and the operating instructions in this manual are followed, a whitish, dusty deposit will form on the inner surface of the glass after a week or so of use. This is normal and can be easily removed when the heater is cold by wiping with a damp cloth or paper towel and then drying.

  • Page 25: Door

    6.3.3 Gasket The glass gasket is flat, adhesive-backed, woven fibreglass. The gasket must be centred on the edge of the glass. Follow the steps of the previous section to remove the glass. Remove the old gasket and clean the glass thoroughly. Peel back a section of the paper covering the adhesive and place the gasket on a table with the adhesive side up.
  • Page 26 6.4.2 Alignement To align the doors, open the doors and slightly unscrew the set screws on the lower and upper door hinges with a 3/32" Allen key to release the adjustable hinge rods. 3/32" Using a flat screwdriver, turn the adjustable hinge rods in the directions shown to adjust the doors.

  • Page 27: Exhaust System

    Apply a bead of approximately 3/16" (5 mm) of high temperature silicone in the door gasket groove. Starting from the middle, hinges side, press the gasket into the groove. The gasket must not be stretched during installation. Leave about ½" (10 mm) long of the gasket when cutting and press the end into the groove. Tuck any loose fibers under the gasket and into the silicone.

    6.5.2 Sweeping the Chimney Chimney sweeping can be a difficult and dangerous job. People with no chimney sweeping experience will often prefer to hire a professional chimney sweep to inspect and clean the system for the first time. After seeing the cleaning process, some will choose to do it themselves.

  • Page 31: Framing Construction

    No part of the fireplace may be located closer to the combustible than the minimum clearance given. A material is considered non-combustible when made entirely of steel, iron, bricks, tiles, concrete, slate, glass or a combination of these materials. Materials corresponding to ASTM E136 and UL 763 are considered to be non-combustible materials with the exception of gypsum, which will be considered a non-combustible material only if it is certified to withstand an ambient temperature of use of 250°F and more.
  • Page 32 Do not use combustible materials for the frame directly above the fireplace. This area should remain empty to a height of 80" (2.03 m) COMBUSTIBLE measured from the base of the fireplace.

  • Page 37 8.6.5 R Factor There are two ways to calculate the R-value of the floor protection. First, by adding the R-values of materials used, or by the conversion if the K factor and thickness of the floor protection are given. To calculate the total R value from R values of the materials used, simply add the R-values of materials. If the result is equal to or greater than the R-value requirements, the combination is acceptable.
