I'm debating purchasing a VC Defiant Encore 2190. It is a blue enamel with the 6" and 8" flue collars. I have a 6" thimble going into my masonry clay lined utility chimney in the basement. It is a dedicated chimney that's not being used. I've heard some things about the fragile refractory housing on these stoves. The seller tells me the stove is in great shape as he took it appart every year and cleaned the secondary burn chamber and cat. He mentions the cat is 6 years old and that he used it to supplement heat and not as a main heater. He has never had a problem with the refractory package. The seller purchased it new in 1994. Can anyone comment on the burn length of this stove? Or any experience with it! How hard is it to get parts for this stove? Does anyone have a link to the owner's manual? I could find one for the #0028 but not the #2190.
