IONAL PROBLEMS The chimney must be swept at least once a year we recommend the use of a NACS na tional association of chimney sweeps registe red chimney sweep In the event of smoke or malodorous fumes being produced you must first check to see whether the chimney is blocked The chimney must of course always provide the minimum draught necessary to ensure that it is possible to regulate the fire Please note however that chimney draft is dependent on the weather conditions In high winds the draft can become so power ful that it may be necessary to fit a damper in the flue gas pipe to regulate the draft When cleaning the chimney soot and other deposits may come to fall on the smoke plate In cases where the wood burns too quickly this may be due to excessive chimney draught You should also check to make sure that the door seal and ashpan seal is intact and correctly fitting If the stove it generating too little heat this may be because you are firing with wet wood In this case much of the heating energy is used to dry the wood resulting in poor hea ting economics and an increased risk of soot deposits in the chimney MAINTENANCE The surface of the stove has been trea ted with heat resistant paint The stove should be cleaned with a damp cloth Anv damage to the surface in the form of chips or scratches can be repaired using touch up paint which is available in sprav cans GUARANTEE The Vision stoves are
