27W415-0762 / B / 11.12.108.4 CHIMNEY CLEANING8.3 RUNAWAY OR CHIMNEY FIRE85.1Runaway fires can be the result of three major factors:• Using incorrect fuel, or small fuel pieces which wood normally be used as kindling.• Leaving the door ajar too long and creating extreme temperatures as the air rushes in the open door.• Burning your appliance with the ash plug not securely seated.SOLUTIONS:• Do not burn treated or processed wood, coal, charcoal, coloured paper or cardboard.• Be careful not to over-fire the appliance by leaving the door open too long after initial start-up. A ther-mometer on the chimney connector and/or appliance top helps.• Always operate the appliance with the ash plug properly installed.IN CASE OF A CHIMNEY FIRE:• Have a well understood plan for evacuation and a place outside for everyone to meet. Prepare toevacuate to ensure everyone’s safety.• Close air control on appliance.• Call local fire department. Have a fire extinguisher handy. Contact local authorities for further informa-tion on how to handle a chimney fire.• After the chimney fire is out, clean and inspect the chimney for stress and cracks prior to lighting an-other fire. Also check combustibles around the chimney and the roof.A CHIMNEY FIRE CAN PERMANENTLY DAMAGE YOUR CHIMNEY SYSTEM. THIS DAMAGE CANONLY BE REPAIRED BY REPLACING THE DAMAGED COMPONENT PARTS. CHIMNEY FIRES ARENOT COVERED BY THE LIFETIME LIMITED WARRANTY.86.1Both the chimney and the appliance must be inspected and cleaned if necessary at least once a year.For serious wood burners, chimney cleaning must be done as needed to avoid chimney fires; the ventingsystems for controlled combustion appliances may need cleaning as often as once a month. These rates,however, depend on the burning habits of the individual operating the appliance. For example, it is possible toclog a solid fuel appliance chimney in a few days if slow, smoldering fires are burned and the chimney is cold.NOTE: Appliances burned consistently without hot fires may result in significant creosoteaccumulations in the chimney.Certain items and considerations are important in chimney cleaning:• Proper tools should be used, including a brush specifically designed for chimney cleaning.• The chimney connector and dampers as well as the chimney should be cleaned.• The appliance’s firebox and baffle system should be cleaned if needed.• The chimney should be inspected and repairs made if needed, preferably by a qualified chimneysweep or mason.
