Nice unit, a little tip, if your burn time are less than impressive there is a air restrictor for that unit and make sure the knock outs are removed in the shell.Whew, finally got it put inRan into a few problems and worked late into the night Saturday but she's finally there. I think it looks pretty good and the wife loves it. Sorry for some of the blurred pictures, someone hasn't figured out the whole flash thing yet!

Firin' it tonight? How tall is your stack?So we heard.Ran into a few problems


That thing put out some serious heat! I'm not at all used to these as I've only used open hearth fireplaces before. It's kinda nice not heating the outside of my house for once. As far as burn times and performance, well I don't know yet. So far it seems relatively promising. I'm just getting the break in fires out of the way so I'm not really pushing anything....OR at least not trying to. I got her a little hotter than I planned because my digital catalytic temp. probe didn't work to well. I kept waiting for the temp to get up to 500
and it never really did. Even though I eventually just closed the bypass and the cat seemed to be firing just fine. The probe never displayed above 500 and just kept flashing between COOL/350/400/450
with brief periodic flashes at 500
. It never settled in on a temp.
and the upstairs was just a few degrees cooler. This morning at 6am the blower was off, the stove was warm, there was a great coal bed and the first floor was 69
. I have no idea how long the blower ran or cat fired but considering when I normally get up the house is around 64
, I couldn't really complain. I don't think that's too bad for two splits of pine. Grant it, the outside temps didn't get anywhere near as cold as expected (around mid+ 40's).
Is the thermocouple installed 2 inches behind the cat? Just an FYI, I have found it will not read correct temps from the front of the cat.
Feel free to checkout my thread on trying to read cat temps from the front: https://www.hearth.com/talk/threads/digital-cat-probe.105221/
I ended up just going back to using my Condar Catalytic Probe to read my cat temps, it was much more accurate from the front.
I put the thermocouple on my exhaust and use that now to see temps from across the room.

!! From 2:30 to 10:30 the house went to 70
with outside temps dropping from low 40's to mid 30's. From 10:30 to midnight the inside temps went to 75
with outside temps dropping into low 30's. This morning I got up for work and there was easily enough wood/coals to last another hour+, so she cruised into 7 hours no problem. I loaded up the firebox again w/mixed odds and two splits of pine. Not as packed as last night but with the amount of coals in there, I couldn't get much more in. Last I talked to the wife, around 2:30 this afternoon, the CAT temp had just dropped to 400
w/the blower still pushin' a lot of heat and the stove radiating just as much. The house was still at 70
with outside temps in low 40's. That's NINE solid hours of heat and she was still cruisin'. Won't talk to the wife again until late tonight so I'll have to wait to see how long it went. Overall, the house was VERY comfortable in shorts/t-shirts all evening and sounds like it's still comfortable today!
. It even started glowing last night before I closed the bypass and the reading was only 400

. At 10:30pm the stove and glass were still pretty warm to the touch and the house still "felt" warm. She didn't even kick the furnace back on until 8:30. I am very pleased right now!
Grant it, the day time temps got into the mid 40's today but I was only expecting 6-8 hours.I have the same problem with the glass in the fall and now spring, in the heart of winter when temps get really cold it is cristal clear the black just burns off on its own. This is common on cat stoves. With the wood when I fill it up I'll fill east west shorter pieces in the back all the way to one side, fill it all the way to the glass and to the top, because the wood is pushed to one side I can fit two pieces north south on the other side.Well, as has been so elegantly put before: "It's gettin' hot in here, so take off all your clothes".
Got a little cool around here so I fired her up around 2:30pm yesterday, started a top down fire then put about 1/2 load in around 4pm. The idea was to get me to around 10pm, that was no problem. I packed the firebox as full as I could at 10:30pm w/odd pieces I had - not even sure what kinda wood. Lit off almost instantly as the coal bed was ridiculously hot!! From 2:30 to 10:30 the house went to 70
with outside temps dropping from low 40's to mid 30's. From 10:30 to midnight the inside temps went to 75

Now for the issues. There's only two complaints I have with the insert. Even on a decent burn, the glass gets black around the lower corners covering all but the center and top. With everything shut down, it really gets dark and it's pretty tough to get clean. The other is the size of the firebox. Actually not so much size but configuration. With the angled sides it's kind of tough to get a good uniform load. I'm sure as I play with it and start getting better wood I'll figure out the best way to load it but for now I can't really get a good/uniform load. I think my burn/heating times would be even higher if I could get a good load.
Lastly is the Condar digital temp. probe. The first one I had didn't really work at all. They sent me a new one thinking it had a bad control board. That was nice but I have to pay the shipping back of the old one. I only used it twice and it didn't work from the beginning! The new one was acting a little weird at first too. I had it powered by their AC adaptor and it kept flashing different temps. It just wouldn't hold anywhere. I ended up using a 9V battery and now it seems to work o.k. I still don't completely trust it though. Last night and this morning my CAT was glowing super bright red and the flame shield was even starting to glow. The temp. never showed over 1050. It even started glowing last night before I closed the bypass and the reading was only 400
I have some good pic's from last night/this morn. but for some reason my phone isn't downloading them onto the computer. It also won't let me post them on here straight from the phone. Damn smart phones![]()
The house has never been warmer. I'm consistantly getting 10 - 12 hours of heat from a load and have hit the 14+ hour mark three or four times since installing
. Grant it, the CAT is NOT at temp this entire time and there is no active flame for most of it but I'm still getting good heat for that amount of time. For those that are curious, I don't consider the loading/firing or heat up time before I engage the CAT in these times. That is actual time that we get good heat w/blower on AFTER I close the bypass.

I have the same problem with the glass in the fall and now spring, in the heart of winter when temps get really cold it is cristal clear the black just burns off on its own.

. Last night, it shot up to 1450
really quickly and stayed there for 2+ hours then slowely dropped to 1350
and stayed there for at least another hour (not sure how long, I finally went to bed!). I didn't do anything any different, used the same wood with roughly the same load as always. The stove temps weren't really any higher than normal either. The only real difference is that I had a little les active flame for the first 30mins or so after I got her going than usual but the secondaries kicked in and the CAT temp still stayed up there.
! The only real complaint I have with this thing is the glass. It really gets black, even on a "high" burn it soots up in the bottom corners pretty quickly. By the end of a burn only the top edge and upper/center is still clear. Other than that the shape of the firebox makes loading a game of Jenga
.The cat thermometer temp jumps up when the battery is low.Quick update, I fired her up last night. Didn't really need too, mostly just wanted too! It was cool and rainy last night, so I figured "what the hey!"
This was my first burn in over a week. I got caught of gaurd by the CAT temps. Usually, the temp gauge hovers around 1050 - 1100. Last night, it shot up to 1450
really quickly and stayed there for 2+ hours then slowely dropped to 1350
and stayed there for at least another hour (not sure how long, I finally went to bed!). I didn't do anything any different, used the same wood with roughly the same load as always.

The only real difference is that I had a little les active flame for the first 30mins or so after I got her going than usual but the secondaries kicked in and the CAT temp still stayed up there.
The good news is that the house is plenty warm today - going on TWELVE hours now! The only real complaint I have with this thing is the glass. It really gets black, even on a "high" burn it soots up in the bottom corners pretty quickly. By the end of a burn only the top edge and upper/center is still clear. Other than that the shape of the firebox makes loading a game of Jenga

!Hi there! Looked this up from your comment on the CI2600 thread. Two questions for you.
Is this the same mix of splits that you were burning with the CI2600, i.e. were you mixing in pine in that insert, too?
Can you load this any better than the CI2600? One of my beefs with out 2600 is that they say it can take a 22" log....well, sure, it can take ONE of those, but then it narrows into the back, so it's not like you can load it full of them.
Thanks!

Could you go into a little detail (eg, dimensions)? I like my HI300 a lot, and one of the things is that it can be loaded n/s. Just thinking maybe at some point I'll have to switch to a cat.I don't much care for the design of the firebox either.

so I agreed with her. If I remember correctly (we looked at A LOT of inserts) the HI300 has a square or rectangular firebox. The HI400 does not. It is wider in front and tappers to narrower in the back. There is what I think they call an "ash lip" in the front that is roughly 2"-3" higher than the floor of the firebox, 24" wide x 4.5" deep. It is basically the same size as the blower which sits directly beneath it. (I think the 300 has the same thing?)
) More importantly though I wish it were square/rectangular. I think that would not only make loading quite a bit easier but also CSS my firewood!Well, most fireplaces are a trapezoidal shape anyway, so I guess it makes sense. The Buck is like that but I can usually find a couple chunks that are bigger at one end...
!!Thanks. 12" deep wouldn't cut it for me. I've really gotten used to loading front to back.
