Page 38: Faulty Chimney And Draft Problems
Maintenance FAULTY CHIMNEY AND/OR DRAFT PROBLEMS - CAUSES AND CURES A sound chimney system is imperative, especially when burning wood. Indoor chimney, either masonry or type “HT” metal chimneys are the best. Because warm air rises, a warm chimney allows the smoke and other by-products of combustion a natural exit up and out the chimney. - Page 39 Maintenance TOP OF CHIMNEY LOWER THAN SURROUNDING OBJECTS REMEDY: EXTEND CHIMNEY ABOVE ALL OBJECTS WITHIN 30 FEET CHIMNEY CAP PUSHED OVER FLUE OR FLUE OBSTRUCTED BY A VENTILATOR REMEDY: REMOVE OBSTRUCTION ACCUMULATION OF SOOT OR DEBRIS IN OFFSET REMEDY: REMOVE AIR LEAKS THROUGH CRACKS IN FLUE AND CHIMNEY DISCLOSED BY SMOKE TEST...
