User manual HASE OTTAWA

[. . . ] Dear Hase customer, In deciding on a Hase stove, you have purchased a top quality product. It goes without saying that we only use first-rate materials and process them with superior craftsmanship and the greatest care and precision. At our headquarters in Trier, Germany, we put our love of detail into every stove we develop and manufacture, thus ensuring that they meet the highest standards in design, functionality, and eco-friendliness. The well-balanced design, state-of-the-art production processes, as well as our efficient and environmentally-friendly combustion technology will let you keep enjoying your Hase stove for years to come. [. . . ] 11/I) is opened too wide poses the risk of overheating the stove (forge fire effect). In contrast, however, the fire box door and ash compartment must always be tightly shut. During shipment, condensation moisture can accumulate in the stove's interior, which may possibly lead to the appearance of condensation or water on the stove or flue pipes. The surface of your stove was treated in a sandblasting machine before applying the colour coating. Despite careful and thorough inspection, there may still be some residual material in the stove body, which can fall out when your stove is being installed. To prevent any damage, please immediately vacuum up these small steel pellets with a vacuum cleaner. The first time a stove is operated, the heat development causes the emission of volatile components from the coating, sealing strips and lubricants, and smoke and odours can occur. 1 Primary Air The primary air is guided through the grate and into the fire box from below, which allows the stove to reach the required fire box temperature more quickly during the warming up phase. 2 Secondary Air The secondary air is guided into the fire box from the top, via air ducts in the stove. It supplies the fire box with the volume of preheated oxygen necessary to completely burn off the wood gas and reduces the build up of soot on the fire box windows. For regulating the secondary air, the following general rule applies: a small fire requires little secondary air; a large fire requires ample secondary air. 11/II) is closed too tightly, there is a risk that the flue gases will not burn completely (smouldering fire), that soot will build up on the fire box window, or that the amassed wood gases will burn explosively (overfiring/deflagration). Fuel Load Sizes and Thermal Output The thermal output depends on the amount of fuel you put in the stove. When adding more fuel, please do not exceed the maximum fuel load size of 2 kg. Exceeding the maximum fuel load size leads to a danger of overheating, which can result in damage to the stove and the risk of a stove fire. At a higher combustion temperature, this one-time process can take between 4 to 5 hours. To achieve this higher combustion temperature, please increase the fuel quantity recommended in Section 16, , , Adding Fuel/ Heating with Nominal Thermal Output", by approximately 25%. Do not attempt to slow down the combustion by reducing the air supply. When heating with wood, this can result in an incomplete burning process and pose the risk of an explosive-like combustion of the accumulated wood gases (deflagration) Heating with Wood at Low Thermal Output Procedure Emptying the Ash Drawer As a safety precaution, please make sure to wait until the ashes are cold before you dispose of them. While the ash collects during the fire, the lid is located under the ash drawer. Slide the lid onto the ash drawer so that it is closed; this prevents ashes from flying around, which in turn means your home stays clean. Piled up ashes can impair or even block the supply of primary air supply to the stove. [. . . ] 2 Flue Gas Paths The stove and flue pipes should be inspected for sediment and deposits at the end of each year's heating period (even more often if required, e. To clean the flue-gas channels remove the upper heatresisting slab and the deflectors, if present (see Instructions for Installation and Maintenance). Use a flexible pipe brush to clean the flue pipe at the cleaning port located on the flue pipe. 4 Fire Box Lining The heat-resisting slabs in the fire box of your Ottawa stove are made of Vermiculite.
