Hello all, first time poster, I hope I'm doing this right. I'm looking at the Napoleon 1402 insert and the Jotul 550. One concern I have is the field of view. I think the Jotul 550 is bigger than the Napoleon 1402. I'm working on a budget so I'm probably leaning toward the Napoleon. Does anyone have any experience with them? Another topic is the liner, I have the 8x13 terra cotta on an outside wall. The chimney is about 33'. Does it have to be an insulated liner? What type of stainless; 304,316,316ti ? Thanks for the help. :cheese:
