1. e The burning rate can now be reduced by moving the top air control to smaller air inlet Re fuelling Figure 4 e Open the lower control e Open the glass door and add logs To load fuel the door should be opened slowly avoiding a sudden rush of intake air so that the smoke does not escape into the room e Leave the lower control open for a few minutes to allow the initial volatiles in the wood to burn Page 12 e Close the lower door control Very Important Wood is a material that contains a great deal of gas approximately 75 The gases are released when the wood is lit and heated up For this reason it is important that the gases are ignited quickly after stoking If the wood just lies smouldering especially after re stoking a lot of smoke is created which in the worst case may cause an explosive ignition of the gasses resulting in damage to the stove In order to ignite the gases that are released from the wood and to keep clear lasting flames during the combustion process it is important to let in the required quantity of oxygen air supply at all times The setting of the air supply the method of ignition and the lighting intervals depend on the draught in the chimney the wind and weather the amount of heat required the fuel etc This means that it may take some time before you get to know the correct functioning of the stove under any given circumstances 3 2 2 Use with solid fuel Lighting Figure 42. equipped with access doors for inspection and cleaning The size of the cleaning door in the chimney must at least equal to that of the cross sectional area of the chimney In the event that a chimney fire occurs resulting from faulty operation or prolonged use of damp wood fuel close the air vents completely and contact your local fire department immediately 2 5 Pipe connections The stove must be installed with a 125 mm diameter flue pipe This must be an approved thickness The flue outlet for this product is inside the burn chamber during transportation You can choose between a top or rear outlet for the flue pipe Flue pipes are placed directly onto the product flue outlet There are three lips on the flue collar These are used to fasten the flue collar into the body of the stove by twisting clockwise see Figure 3 The unused outlet must be sealed with the plate and screwed firmly into place Note It is important that the joints are completely sealed Air leakage etc may lead to malfunction Page 7 Figure 3 Open Close O o eS Se Q 2 6 Connecting to a masonry chimney A wall sleeve should be bricked securely into the wall of the chimney at the appropriate height and the stovepipe inserted centrally The pipe must not extend into the actual chimney opening but rather must reach only to the inside of the chimney aperture The gap between the stovepipe and sleeve must be sealed using glass fibre packing rope
3. 2 7 Connecting to a steel chimney If your installation involves taking the chimney straight up and through the ceiling you must comply with National Local Building Regulations or flue manufacturer s instructions concerning clearances to combustible materials such as walls floor joists and ceilings The joint between the stove flue collar and the stovepipe must also be sealed using the glass fibre rope provided It is important that the insulated flue system is properly supported both at ceiling level and at roof level THE STOVE MUST NOT BEAR THE WEIGHT OF THE CHIMNEY SYSTEM See chimney manufacturer s instructions Excessive weight on the stove will inhibit expansion and could lead to damage of the stove top In the event that a chimney fire occurs resulting from faulty operation or prolonged use of damp wood fuel close the air vents completely and contact your local fire department immediately Page 8 CAUTION Cleaning procedure Discuss this with chimney sweep or qualified installer prior to or during the stove installation Chimney draft If the chimney draft is naturally poor it is better to install the flue from the top of the stove so as to minimise any internal resistance of the flue gases Avoid having any more than 2 bends in the flue system and limit the length of the offset between bends Fresh air supply A wood burning stove requires air for combustion and therefore you may need to install additional ventilation t

8. for heat the combustion will be poor The stove provides too much heat so the combustion should be reduced But always remember to make sure that there are lasting flames until the wood becomes charcoal If you want a weaker fire stoke up using less wood If you fire the stove using wet wood a lot of the fuel s thermal energy will be spent forcing the water out of the wood without releasing any heat to the stove This incomplete combustion results in a layer of soot being left in the stove pipe and chimney Figure 4 the secondary air inlet 3 2 3 Ash removal It is essential to keep the grate free from a heavy build up of ashes This product is equipped with a grate riddling device which is used to shake ashes off the grate into the ash pan Whenever the stove is burning lifelessly and the lower control is open use the riddling lever to clear the grate of surplus ashes If burning solid fuel always empty the ash pan at least once a day or whenever it is full of ashes Never allow the ashpan to overfill allowing ash to be in contact with the underside of the grate If this condition is allowed the grate will wear out pre maturely Page 14 3 3 Maintenance 3 31 Cleaning glass This product is equipped with an air wash for the glass Air is sucked in through the air vent above the fireplace and down along the inside of the glass However some soot will always stick to the glass but the quant
