ment point). If measured just above the smoke flue socket, the chimney draught must be 18-20 Pa. The chimney must have a minimum clearing of Ø125 mm or Ø150 mm. The chimney must be provided with an easily accessible cleaning door. The chimney and flue duct must be of flue class T400 and be CE marked. Furthermore, it must have obtained the classification of G in soot fire testing. The required distance to combustible material must be complied with in accordance with the brand label.
plate so there is room for the smoke outlet. 6. Removing the cover plate (3). Remove the cover plate on the back of the stove by removing the three screws (Torx Bit no. 30). 7. Removing the flue ring (4). Remove the three screws. Lift the flue ring off the top of the stove. 8. Installing the flue ring (4). Insert the flue ring into the smoke outlet hole in the rear of the stove and secure it with the three screws. 9. Installing the cover plate (3).
• Two-piece smoke defector plate (6). Each half is hung on the hooks located beneath the top plate. The two halves join in the holders behind the air pipe. Once the stove has been installed, twist the protection off the two hooks by using pliers or a screwdriver. • Removable rear plate (2a), covering the HWAM® Autopilot™. This must always be mounted if the stove is placed next to a combustible wall. • Removable heat shield (2b) - HWAM 3520.
Firing manual - wood Your first heating session The lacquer will be fully hardened after the stove has been used, and the door and the ashpan should be opened very carefully as there will otherwise be a risk that the gaskets will stick to the lacquer. In addition the lacquer may initially give off an unpleasant odour, so make sure that the room is well ventilated. Tips about fuel Approved fuel types The wood burning stove is EN approved for combustion of wood only.
Special lighting guide for wood-burning stoves with stone cladding Stones are a natural product that must be allowed to adapt to fluctuations in temperature. We recommend following the procedure below: 1. First stoking Turn the air control knob (drawing E, 1) clockwise to maximum. Place two pieces of wood (5-8 cm in diameter) horizontally in the bottom of the combustion compartment (corresponding to 1-2 kg). Place 5-8 pieces of kindling randomly on top.
Stoking (drawing E) When there are no more visible yellow flames, and a right ember is there, you can fire again. The layer of embers is suitable when the pieces of wood begin to disintegrate and the bottom of the stove is covered by embers. Carefully open the door to prevent smoke and embers from escaping. Put at least two pieces of wood into the stove, weighing up to 1 kg each.
Firing in general Rapid or fierce heat Rapid or fierce heat is obtained by burning many small pieces of wood. Maximum amounts of fuel: The maximum allowed amount of fuel per hour is: Wood: 1.46 kg If these limits are exceeded, the stove will no longer be covered by the factory guarantee, and it may also become damaged due to excessive heat, the glass may turn white, for example.. The stove has been approved for intermittent use.
Maintenance Cleaning Any maintenance of the stove should only be carried out when it is cold. Daily maintenance is limited to vacuum cleaning the stove externally, using the soft brush attachment. You can also dust the stove using a dry, soft cloth or brush. But remember, only when the stove is cold. Do not use water, spirit or any other kind of cleaner, as this will damage the lacquer. Once a year, the stove should be thoroughly serviced. The combustion chamber should be cleared of ashes and soot.
On a cold stove, the starting point of the feeler is controlled. The starting point on a cold stove is about 300 above horizontal. It should feel easy going and bouncy when you push it, no matter if the stove is cold or hot. By rising or falling temperatures it must not move at a bound. The damper plates must be dry and clean and slide together unhindered. Control bars and slide gates may have to be smeared with WD40 (never oil).
