studies conducted by the University of Georgia found that the amount of damage wood left on the chimney was a result of low-temperature fires rather than a resin rich fuel source. While pine does contain more sap than other types of wood, this is no longer considered to be cause of creosote buildup in chimneys. Wood that does cause problems though is burning green wood or burning fires at low-temperatures.
i lived in a part of MAINE...where PINE & CEDAR are burned only. reason being, it is plentiful!!! most people that did this kept a "hot fire" going.
