Just bought a new 4100i to replace a 30+ yr old Appalachian insert. Doing the install myself, with a helper. Question for you experienced guys, is it advisable to block the insert up off the hearth base...or best to sit it right onto the bottom? The previous insert sat flat on the bottom. I find the flue liner, that I installed 4 yrs ago...is too short to reach top of new insert...so I need to add in a piece.

Hi Brogan, I've done it both ways, sitting it flush and raising it up. On my one install, I had an original firebox that had a recessed floor( I'm almost sure that's not the right term for it" but the floor of the firebox dropped down about 2" from the hearth. I cut sections of 4" steel channel to act as shims on that one. If I recall correctly it allowed me to shove the insert into the firebox, and the bottom dropped in quite nicely for a clean look.

If your new stove is too short, I would think you could shim it up, with steel or brick ( I'd use solid concrete blocks) Any gaps that remain after the install can be trimmed out with expanded metal painted black. I think it would be hard to add to a flex liner which is what I think I see in your picture. Hopefully others will chime in.
 
I just placed the insert on the base and bought a 12" extension to the flex liner. Took a video of fire on it's 4th burn. Looked pretty awesome to me

One thing that I find...I push the ACC control all the way IN and turn on full air....and crack the door to get fire going....maybe 30 mins.
Using the ACC like the book says...doesn't seem to work so well.

i agree with you 100%....it took me 2 hours to get the fire started the first time on my 4100i.....i push the ACC in the whole way with door cracked to get it started then once its established ill push and pull out the ACC....i love the wood burner!!

Sharp looking unit and some nice flames there!

Do the side bay windows stay clear too? It's hard to tell in the vid.

I had a Quadrafire 5100 bay insert, the side windows did soot up over time, but were easy to clean with some ammonia glass cleaner. One of the prettiest burning stoves I've ever owned. The two air controls had a learning curve, but it was fairly short.
 
Per the video it looks like the airflow is coming out vertically on the sides of the unit - interesting. That raises the question though - what happens to all the heat at the top of the unit?

Curious if anyone know the actual airflow pattern of the fans and if they are extracting any of the heat off the top?

It has a convection top. The outlets are narrow slots right under the lid.
 
Not so clea. Not black, just not clear. The front window, however, is fantastic. Burning 5 year old hardwood, stored under cover. Before I started first fire, I looked around inside firebox...struck me as strange there were ZERO holes drilled in roof of firebox above side windows...yet they are drilled above front window. If I had the balls to do it...I'd drill 2 holes above each side window...makes sense to me it'd work. I tell myself I could weld over them if it was a disaster.

Yes, air output is under the top plate. The blower puts out a lot of air, has a large adjustment range.
My old stove, a ~40 yr old Appalachian was so loud you couldn't hear the tv at full speed. This is much better. Still not quiet, but it is an insert.

Nice looking insert! Are you going to add a surround?
 
Yes, the surround is now fitted. I left it off to ensure all was well. The insert cranks out an extraordinary amount of heat. Glad I didn't go for a bigger one. Last night at 8pm, I filled the box as full as I could, on top of a really great going base fire. Cranked the air for 30 mins, then shut it all the way down. This morning, fully 12 hrs later, there was still a full bed of glowing coals, added a few small splits and away she went. I have "fluffed up" the door gasket and tightened the door catch a little to really air tight the door. Pretty pleased with it....as well as saving the $800 install charge.

I'm glad your enjoying your new insert!
Was your Appalachian a EPA approved stove? It is amazing how much heat a EPA stove can put out with dry wood in it.
It would be great to see a pic with the surround on.
 
I agree that the ACC controls are a bit tricky to figure out.... I'm on my third season and still learning.
