Happy new year to everybody . Two years ago (Dec.16') my fireplace chimney was burned . Before that and for several months I was burning woods of black pine , which , in addition to the high content of resin , they were not seasoned . This December, the chimney burned again , despite the fact that the wood are right in all respects . I burn the fireplace every day , but I take away the ashes of the previous days , every 10-15 days . The remaining ash that stays inside becomes powder . Question: Do I stress the ash conditions for ignition of the chimney ? Does the ash / powder stick to the already existing creosote and to the constantly created creosote and the ignition becomes more likely? Thanks in advance for any answers .
