HOT DO NOT MANIPULATE WITH BARE HANDS ODOUR FROM THE PAINT It is normal that a smoke odour emanate from the unit when you first light it It is recommended to burn it at high rate and ventilate the building until the odour resorbs ASH DISPOSAL Ashes must be placed in a metal container with a tight fitting lid The container should be stored outdoors well away from combustible materials If the ashes are meant to be buried in soil you should wait until all cinders have thoroughly cooled CREOSOTE BUILD UP AND REMOVAL When wood is burned slowly it produces tar and other organic vapours which when combined with moisture form creosote The creosote vapours condensate in a relatively cool chimney flue As a result creosote residues accumulate on the flue lining N B To minimize the frequency of chimney cleaning buy your firewood at least one year before using it Store it in a dry place in order to obtain the minimum moisture content and optimize the efficiency Do not store wood or combustible materials within the installation minimum clearances or the space required to reload the appliance and remove the ashes When ignited creosote produces an extremely hot fire inside the chimney To avoid chimney fires it is important to do the turnover of wood Inspect the chimney system at regular intervals to determine a cleaning cycle A weekly cleaning might be required during mild periods while a monthly cleaning should be sufficie
