Hi,im new to the fourm and im looking to get a baby bear for my 1000 sq foot home.small open style concept home so i don't think the size will be a issue heating.my question is will it be ok to place about 1/4 of the back into an exsiting fireplace so the pipe goes up chiminey so it doesn't stick into the room a lot? there was previously a small wood stove before I got the house so there is a pipe already up the chiminey.and I assume there needs to be a block off plate with 6 inch hole,would that be correct?im open to other options but a fisher baby bear is high on my list as my grandmother had one in her home as I grew up.thank you for all your time
