3. Cracked or defective chimney flue or liner Down Drafts Trees or other topographi cal barriers may impede on chimney performance causing air currents to be pushed downward into the flue This can also be caused by neighboring buildings or other chimneys Creosote and condensation If creo sote or condensation runs out of the chimney or stove pipe check the following Chimney cap or liner may be defective Boiler may be positioned too far away from the chimney which would not allow the chimney to warm Wood being burned may be green or wet Boiler may be over sized for the residence causing it to be burned on low too often Excessive Draft This can be controlled with a barometric damper in the stove pipe 12 Maintenance Maintenance The spiral chamber is basically self cleaning However if there is a draft problem and you have been burning wood for a long time with little demand the spiral chamber will need to be cleaned To clean the spiral chamber remove the stovepipe and scrape any creosote or debris from the top and front of the chamber The rear of the chamber should not have much accumulation If it does clean it out NOTE 1 4 to 1 2 of creosote in the spiral chamber is normal The pipes inside the firebox will accumulate creosote if the demand for heat is too low when burning wood 1 8 to 1 4 of creosote is normal on the pipes and firebox walls If more creosote has accumulated it should be scraped
4. controls on the firebox door are used to allow secondary air to pass over the fire when burning coal This helps to burn the gasses that are emitted from the coal as it is heated Your setting for these draft controls should be between 1 2 and 1 complete turn from closed Adjust both controls equally Loading Coal should never be added unless there is a reasonably hot fire The coal bed should be bright and vigorous If you have an active coal bed full loads can be added at any time If not add new coal in layers as described in starting a coal fire Shaking the Grates Shaking should be done only when there is a well established fire The frequency of shak ing will depend on the degree of burning Twice a day shaking is recommended The best results are achieved with short choppy strokes as op posed to long even strokes Full rocking of the grates may allow burning coal to fall into the ash pan The amount of shaking is critical too much can disrupt the fire bed and too little will restrict air flow The proper amount of shaking is normally achieved when hot red coals first start to drop through the grates into the ash pan Every effort should be made to not let a coal fire burn down too low This will cause the reloading process to be much longer with a real good chance of losing the fire altogether Do not shake or stir with a low fire Open the ash pan door to get maximum air flowing into the firebox Once burning is re
