  • Page 17 3. Cookstove operation Components use Cooking with a wood-burning cookstove is an art that requires several attempts to get to know and control the appliance. Many factors can influence how the cookstove will heat the oven and the cooking surface. Among them, the type of fuel used and its quality, the size of the logs and when to load before cooking.
  • Page 18 3.1.1 Oven Figure 20: Oven door closed Figure 21: Oven door open The cooker has a stainless steel oven to cook or bake food. The panoramic glass of the oven door allows you to watch your meal without having to open the door. During cooking, keep the oven door closed to maintain a constant temperature.

  • Page 20 3.1.3 Cast iron cooking surface Figure 24: Cast iron cooking surface It is not recommended to cook food directly on the cast iron top, as the paint used is not food grade. The cast iron cooking surface on the top of the range is designed to provide intense heat to allow food to be cooked.
  • Page 21 Gas path Figure 25: Gas path The gas path is in fact the circuit followed by the hot gases emitted by burning wood. This circuit is used to heat the stainless steel oven and the cast iron cooking surface. The primary air supply provided by the pilot feeds the wood combustion. Wood burning in the combustion chamber gives off particles and hot gases heading upwards.
  • Page 22 Blower Operation It is possible to install a fan on this cookstove. See the Parts List section at the end of this manual for the original part number. The blower is installed on the back of the cookstove to increase the airflow through the heat exchanger and improve hot air circulation in the room.

  • Page 24 Log Length Logs should be cut at least 1" (25 mm) shorter than the firebox so they fit in easily. Pieces that are even slightly too long makes loading the stove very difficult. The most common standard length of firewood is 16" (400 mm). Piece Size Firewood dries more quickly when it is split.
  • Page 25 Here are some facts to consider in estimating drying time: − Firewood bought from a dealer is rarely dry enough to burn, so it is advisable to buy the wood in spring and dry it yourself; − Drying happens faster in dry weather than in a damp climate; −...
  • Page 26 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 27 Place three or four small, split, dry logs in the firebox. Arrange the kindling wood on the logs in two layers at right angles and place a dozen finely split kindling on the second row. It is possible to use ragged paper but it may not hold in place since it tends to roll while it is burning.
  • Page 28 Rekindling a Fire Generally, when you need to cook, it is time to reload. Remove excess ash from the front of the firebox and bring the ashes forward. Place a new load of wood on, and at the back of the embers.
  • Page 29 On the other hand, too much air can make the fire uncontrollable, creating very high temperatures in the unit as well as in the chimney and seriously damaging them. A reddish glow on the unit and on the chimney components indicates overheating. Excessive temperatures can cause a chimney fire.
  • Page 30 6. Maintenance This cookstove will give many years of reliable service if used and maintained properly. Some of the internal components of the firebox, such as vermiculite and baffle will wear over time under intense heat. Defective parts should always be replaced with original parts. Firing each load hot to begin a cycle will not cause premature deterioration of the cookstove.
  • Page 31 Grills and cast iron cooking surface Clean the grills with a brush and mild soap. To clean the cast iron cooking surface, wipe it with a soft and damp cloth. Do not clean the surface when it is hot. If rust or scratches appear, follow the instructions in section 6.4 Cleaning and painting to repair the surface.
  • Page 32 Glasses The cookstove has two glasses to maintain. The combustion chamber glass has a gasket while the furnace does not. 6.6.1 Cleaning Under normal conditions, the door glass should stay relatively clear. If the firewood is dry enough and the operating instructions in this guide are followed, a whitish, dusty deposit will form on the inner surface of the glass after a week or so of use.
  • Page 33 6.6.2 Replacement The glass used is a ceramic glass, 5/32" (4 mm) thick, tested to reach temperatures up to 1400º  F. The dimensions of the glass are 17 5/8" x 9 9/16". If the glass breaks, it must be replaced by a ceramic glass from SCHOTT with the same specification. Contact your dealer to obtain a genuine replacement part.
  • Page 34 6.6.3 Replacement The glass used is a ceramic glass, 5/32" (4 mm) thick, tested to reach temperatures up to 1400º F. The dimensions of the glass are 17.5" x 5.375".

  • Page 35 6.6.4 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 Stick the end of the gasket to the middle of one edge,...
  • Page 36 6.6.7 Door sealing In order for the stove to bur n at its best efficiency, the door must provide a perfect seal with the firebox. The tightness o f the door seal can be verified by closing and latching the door on a strip of paper. The test must be performed all a round the door.
  • Page 37 6.6.9 Door Alignment To align, open the door and loosen the pressures screws located on the lower and upper hinges of the door using a 3/32” Allen key to free the adjustable hinge rods. Figure 31: Release eccentric hinges Figure 32: Adjust eccentric hinges Using a flat screwdriver, turn the adjustable hinge rods in the direction shown to adjust the doors.
  • Page 38 6.6.10 Gasket It is important to replace the gasket with another having the same diameter and density to maintain a good seal. Remove the door and place it face-down on something soft like a cushion of rags or a piece of carpet. Remove the old gasket from the door.

  • Page 50 6.16 Exhaust System Wood smoke can condense inside the chimney, forming a inflammable deposit called creosote. If creosote builds up in the system, it can ignite when a hot fire is burned in the stove. A very hot fire can progress to the top of the chimney. Severe chimney fires can damage even the best chimneys.
  • Page 51 N.B. It is possible to remove the chimney after sweeping. The residues will thus all have fallen on top of the oven. You can also remove the chimney before sweeping and make sure to put a container as airtight as possible at the end of the chimney (where it has been unscrewed), to collect the residues that will fall during the sweeping.

  • Page 65 Venting systems that rise straight up from the stove flue collar provide the best performance. Chimneys that rise inside the warm space of the house tend to provide a small amount of draft even when there is no fire burning. This means that when a fire is lit, the smoke goes up the chimney and strong draft build quickly as the chimney flue warms up.
  • Page 66 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 bu ilding supply stores. These components are not usually tested to a particular standard and certified as compliant.
