    I asked awhile back on opinions on our insert install and got some advice from begreen (https://www.hearth.com/talk/threads/kuma-vs-osburn-vs-analysis-paralysis.169354/). In the end I've gone with a Kuma Sequoia and had it installed today. Real world info on the Kuma seemed somewhat sparse, so I thought I'd start a thread to document my experience. We're fast approaching shoulder heating season, so I plan to 'break in' the stove soon.

    About our install: The stove is on the top floor of our house (~1800sq ft). We have ~1100 sq feet downstairs that is heated by a Quadrafire 1200 pellet insert. Downstairs is not as 'lived in' as upstairs, so the pellet stove will be used mainly in the evenings or when guests are in town. We have a very large centrally located hearth and large windows upstairs. Solar gain on sunny days provides most heating needs (which is most days in CO), but the windows let a lot of heat out at night. Good heat output and overnight burns were a driving factor. Others were limited installers in our area. Flue length is ~16ft and due to the central hearth location we are not using an OAK.

    Prior to pulling the trigger I emailed with Jason at Kuma some and came to the conclusion that the Sequoia offers few disadvantages compared with their smaller offerings. The disadvantages were: 8in duct requirement and a less-good airwash system for the glass. Advantages: lower low burn, (much) higher high burn, more efficient burn, and of course, larger firebox. It's probably overkill for our heating needs, but with the lower-low it should work well as I learn how to load it for conditions.

    Our install was fairly uneventful. The insulated 8in flex pipe was a bit of a challenge for the installer in our 13x13 (od) tile chimney. We also had a heatform/heatilator firebox that he had to put a large cutout in. It took him 5hrs of solid work. I had to hire a professional to appease my insurance company, but I'm glad I didn't try it myself...it probably would've taken me a full and frustrating day.

    I'll update this page with my experience as I learn the stove...perhaps it'll prove useful for others considering it.

    for some reason she looks small for such a huge stove/insert. Looking forward to the review when you get burning!

    Go Rockies!

    It does look small. Our chimney/hearth is pretty huge, though. We will probably put a mantle in eventually to break up the visual mass, but with the heatform it would've had to be too high. With the sequoia it should allow us to put it at a reasonable height. It is a big stove, though!

    I've got a 'break in' fire going now. I was warned that it'll smoke and stink the first time, so don't wait until it's cold. We have some heating temps coming up in the next day or two, so I wanted to get the first burn out of the way. It's in the 60s now and I've got the house wide open with a good breeze. Smoke isn't noticeable (yet). There's definitely some smell, so I'm glad I've got the house open and the wife away.

    It'll take some learning to figure out when to close the door and when to engage the cat on a cold start, especially since I can't see the cat temp probe. There was no draft issue, even with the warm outside temps. It's up and running now at about a 1/2 damper setting. The glass blacked up pretty quickly. I can still see the logs, but it's far from clear. I'm sure flames would be visible at a higher burn at night, so hopefully that'll keep the wife happy.

    Wowzers… If I had a place like that I'd be looking at building a masonry heater, centrally located in a home with a fairly open floor plan.

    Congrats on the Sequoia, your place looks great! My Sequoia should be here Monday. Probably wont get a chance to burn until Nov but Im already looking forward to it. So it sounds like the paint smell wasnt too bad? That smell makes me sick to my stomach so Im going to do a few break in fires outside first. Keep us posted on how it does.

    The Sequoia was the only non-BK stove that made it to the last round of selection when I was choosing a stove. I still think it sounds like a great stove.

    There are usually more questions than answers about it here, so please hang around and post your experiences for future stove shoppers to read!

    Also, consider progressively bigger hotter break in fires before you close all the windows and use the stove for heat. Stove paint stinks again every time it hits a new temperature plateau.

    Thanks! The paint smell wasn't too bad, but I did have the house wide open and it's a windy day...so, I wouldn't expect it to have stuck around long. It was noticeable, but not oppressive.

    Will do. I could find little on the Sequoia when I was debating, which is part of the reason for posting here.

    The manual didn't say anything about small break in fires, so I just went for it. I burned it pretty hot today after letting it simmer a bit, so hopefully that took care of most of the paint cure. Ended up with it putting off heat for ~5hrs (when the blower turned off), which is maybe a bit much for a break-in. I'll be working from home Friday and temps should be lower so may get a windows-close or mostly-closed burn in then to finish it off if I haven't already.

    Well, the last couple of days have required the use of the stove. Lows at night have been in the 30s. High today is 47 and rainy, so little solar help. I've only cold started the stove twice, but have had no draft problems. The stove will crank the heat pretty good if wide open. I've burned pretty open in the mornings to kick things up, but most of the time the air is mostly shut down. It definitely has a low-low. The first day mid-afternoon I thought it had burned out and opened the stove up and it still had most of a couple splits smoldering away. I haven't tried filling it or trying to get super long burns, but plan to load it up tonight. It's supposed to bottom out around 30 and continue to rain, so no worries about too much heat.

    So far I'm happy with our choice, and glad we didn't go smaller. I like the cat's low burn, too. The only major downside is coking up the glass. After a couple days burning it's fully opaque, and it blacks up pretty well on the first burn after cleaning. We knew clean glass wasn't the stoves strong suit, but being able to see better would help the learning process.

    Attaching a pic of the cat glow on high early one morning (clean glass!) and a burn pic.

    I'm going on my third season with my sequoia stove, I'm very happy with the burn times. Large locust rounds will last over 16 hours. My setup is a free standing stove in the basement, the glass doesn't stay clean. Just a result of the sequoia. You will get better by reading the temp gauges on the stove and as you burn it more. Burning it wide open it makes some heat so be ready to stay warm!

    I'm burning (almost) all softwood, and did finally load it full one night around 8pm and let it cruise on low. By 6:30 the next morning it was still going with maybe 1/4 of the load left. I think 14 hours would be no problem, even with our pine varieties. During 'real' winter (single digit or lower lows) I'll need more than a full-closed burn. A full load should still give easy overnighters, even with more heat output, which'll be nice.

    I think I'm going to pull the surround for a day or two so I can see the gauge, just to see if my usual operations are using the cat efficiently. The manual suggest 20-30mins of burn with the door cracked, which seems excessive. I usually keep door cracked until it's going well (5-10 mins tops), then shut the door with air wide open for maybe 5 more mins, then close the bypass. On hot reloads I only have the bypass open for less than five minutes before closing again. I don't want to ruin my cat, but don't want to waste heat/wood, either.

    I should mention that I'm mostly burning lodgepole pine and spruce, with some pinon pine, aspen, and cottonwood here and there. It's all stupid dry (my cheapo 'Dr. Meter' won't even measure much of it), so it lights up quickly.

    I’d get that door shut ASAP on any fire. Just long enough that shutting the door doesn’t snuff it.

    I understand that you use dry softwood, but 5 min is too soon in my opinion to close the bypass. I usually wait when all the wood charred and fire is going. Black glass might be because of wet wood, choking air too soon, closing bypass too soon.

    When I go to reload my stove I open the bypass and give it a few min to adjust before opening the door and putting more wood in. Something about the cold air being let in can hurt the cat if opening the door to fast and the bypass not being opened long enough to let the gases go past the cat and up the chimney. Once reloaded i once again give it about ten min or so to get going before closing the bypass. I watch that probe thermostat to let me know when it is up to temp and the cat is ready to engage
