Well after 2 months of telling my mom she is doing somthing wrong ive com to the conclusion , the nc 30 does not live up to the reviews. We are both burnin the same 1.5yr seasoned wood, me in my napoleon 1400 and her in a newly installed summers heat. This stove does not hold a 600degree stovetop for anymore than two hours,then its nothing but a pile of coals. Spring tip to ash lip on the draft. smokepipe is 72" then ceiling support from there stainless up through 2ndstory which is closed off from the rest of house. does anybody that lives up in a northern climate have any input . thankyou
