Ten Foot Rule especially when installing a termination on a high pitch roof Fig 5 The key points of the Ten Foot Rule are 1 If the horizontal distance from the chimney to the peak of the roof is 10 3m or less the top of the chimney must be at least 2 610mm above the peak of the roof but never less than 3 914mm in height above the highest point where it passes through the roof 2 If a horizontal distance from the chimney to the peak of the roof is more than 10 3m a chimney height reference point is established that is on the surface of the roof a distance of 10 3m from the chimney in a horizontal plane The top of the chimney must be at least 2 610mm above the reference point but never less than 3 914mm in height above the high est point where it passes through the roof Fig 5 Ten Foot Rule illustration Vermont Castings EWF36A Chimney Supports The chimney system is supported by the fireplace for vertical chimney heights less than 30 9m above the hearth Chimney supports are required if the vertical height exceeds 30 9m Locate chimney supports at ceiling holes or other structural framing at 30 9m heights Spacing between chimney supports must not exceed 30 9m Use Chimney Support Model TCS8A NOTE The TCS8A cannot be mounted directly to the fireplace Support provided by elbow straps fulfills the support requirement only if they are spaced as pre

10. Chimney System A Clean Chimney System is Safer and Works Better Although the combustion system in the EWF36A can re duce creosote formation dramatically it is not a substi tute for regular inspection and cleaning of the chimney and chimney connector Learn to Recognize and Avoid Creosote The EWF36A has been designed to reduce creosote build up significantly However regular chimney in spection and maintenance must still be performed For safety good stove performance and to protect your chimney and chimney connector inspect your chimney and chimney connector on a regular schedule Clean the system if necessary Failure to keep the chimney and connector system clean can result in a serious chimney fire When wood is burned slowly it produces tar organic vapors and moisture which combine to form creosote The creosote vapors condense in the relatively cool chimney flue of a slow burning fire As a result creo sote residue accumulates on the flue lining When ignit ed this creosote makes an extremely hot fire within the flue system that can damage the chimney and overheat adjacent combustible material If a significant layer of creosote has accumulated 1 8 3 mm or more it should be removed to reduce the risk of a chimney fire If you do experience a chimney fire act promptly to e Close the primary air control lever and the damper e Get everyone out of the house e Call the Fire Departmen
