This could be a dumb question but.... I recently changed my 90* elbow coming out of the back of my Jotul wood stove to a "T" cleanout. Could this effect my draft? It doesn't seem like my fires get going very good anymore. I use to barely have to open my draft wheel to keep the fire going now sometimes I have to leave the draft wheel wide open or even crack the door. Is something else causing this or could it be the pipe change I made? Thanks in advance for any info.
