Hey everyone! I've been lurking for a while and am ready to jump in. It doesn't get too cold here in SC but gas heat is very expensive and I love wood heat. Had a chimney sweep come by today and "inspected" and "cleaned" things. I felt less than confident in these guys...after 10 min he said "you passed inspection" and then with one pass of the broom and 15 min later he said "you're all set". Never got on the roof. $225. Maybe I expected too much.

Plan:
Install Englander NC30 (with legs, probably shortened) in my existing (ex-gas) fireplace which hasn't been used in 15 years. Install insulated liner in existing straight 8x11 clay lined 20' exterior chimney. Fabricate block-off plate. Maybe extend hearth with tile.

Issues: It looks like it will be pretty straight forward install except for the flue being offset from the middle of the fireplace. It is on the far right side of the fireplace and I'm not exactly sure how I should go about attaching the Englander to a flex liner. My thoughts were to put a 45 adapter on the stove flue and see if the flex liner can make the turn to attach to it. It looks like it will work. If that doesn't work I can maybe put another 45 on the end of the liner.

Questions:

Can a flex liner make a tight 45 degree turn?

Where are people getting their liners? Seems to be lots of online dealers.

Since it's a straight, clear chimney should I try to use a rigid insulated liner with a 45 adapter at the bottom? The flex seems very easy to install.

Now the pictures starting with a video that probably explains better of what I'm dealing with.



Here's a mockup of what I'm thinking:

A couple of comments:

- Your hearth will have to be extended out at least 16" (IRC) past the front door of the stove (see page 8 of the manual; if you don't have one, let me know and I'll see if I can attach it).

- What is under your current hearth? concrete or wood joists? The 30-NC requires a R = 1.5 rating for it's hearth, which is 4 layers of Durock Next Gen concrete board. An inch or so of rock and/or slate won't do it. See page 9.

Pics of my 30-NC install:

Thx, good info. I had planned on extending the hearth but now it will be a priority. My clearance is nowhere near 16". I have concrete under the slate now but will need to beef up the hardwood floor area. I think I have the manual or can get it from HD. Your fireplace turned out great. I'm sure it puts out great heat being so open.
