Ok so I'm very new to pellet stoves but am kind of in a bind.

I am currently replacing my steam boiler and am using a 6039HF as my primary and only source of heat right now. Its working out good but I have a feeling it could burn much better if I understood it better.

The instructions say to have the damper fully open for any heat setting above #4. I ran it on HR5 all night with the damper fully open and found the glass became pretty dirty after 12 hours or so. Is this normal or can I get much better results by running manual settings?


I'm also not quite grasping the point in the manually controlled damper. Why is it necessary if there is a variable speed draft fan?


I have no problem tweaking things in fact I enjoy it, but the instructions that came with the stove are pretty much useless.


I am burning wood pellets from tractor supply co.

Not anything to do with members ignoring you.....probably all the US Stove owners aren't home from work yet (not too many of them on the forum compared to other brands). You'll get some responses soon.
 
Yep. Dont know alot about that model. Watch some YouTube videos of different stoves burning. That way you get an idea of what the flame should look like. The more fuel you burn, the more air is needed. Needs a "perfect" fuel/air ratio...

There are a few US Stove owners here. Take j-takemans advice and PM schoondog.
 
Hey Chris,
I have the 6039 insert. Close the damper then pull it out maybe 3/4 of an inch to 1 inch. Go ahead and play around with the damper all you want once the stove is upand running. I never have it out more than 1 -1/2 " certainly never all the way out. You want it more closed than open. Get the flame dancing and give it just a little more air. You will get better heat and better pellet economy. Let us know how you make out and let us know what pellets you got at TSC.
And ya I'll be huntin on Saturday ! :)
 
you might try IBURNCORN.COM forum even if you dont burn corn. the sections are brand dedicated so youll find more people using your particular brand there. i think that stove is common amongst cornburners as well

Thanks for your response! I have attached a picture of the door glass after 1 hopper worth of pellets burning through the night as well as a picture of the bag of pellets from TSC.
Not sure of the quality as I have nothing to compare them to. They seem to be very broken up (not very long). I have two bags which I bought from TSC back in April which say "HARDWOOD HEAT" which at least to me, seem to be better overall.


I had a feeling I wasn't using the damper right, but it confused me because the instructions say to have it wide open for all heat levels above HR-4. I'll play around with it quite a bit more once it cools down again tomorrow. I don't think I'll need it tonight.

I'm assuming the ONLY thing that having it all the way out gets you is more fly ash and blowing more heat out of the vent?

schoondog, do you run automatic settings or dial in manual ones?

Chris, I think bag in photo are Maine Woods. Hardwood Heats are a better pellet imho. Take a gander at the sticky links the webby put at the front page of this forum. There are tests fron pellet master jtakeman that will provide you some very valuable info. Pick a pellet that has a high heat value. Hardwood heats are ok. I hink the Maine pellets are lower in heat output. Somersets are great pellet in this stove. These are multi fuel units that will eat any pellet, but our heat exchangers are not the best. Thats why I try to find the hottest pellet and dont care about fines and ash. Get your self a thermometer ( a meatthermometer will wok) and measure your output temps when running.Try to be conistant with placement and stove settings (i.e. always tke readings after 1/2 hour of running and at same HR) Keep a logbok of what pellets are hottest.
Remember to keep the damper out at least 1/2" more like3/4 to 1" You will find a sweet spot there. Damper wide open will send half burned pellets out of burnpot and heat out vent. I usually use the auto mode now, easier for family to use when I'm not home. You can use manual modes, I used too, just don't have time any more. I SRONGLY recommend reading the owners manual carefully and go to iburncorn to get some great diagnostic and running info. I've got three years on my unit and she still works great. I may even fire it up tonite, freeze warning in effect. Good luck and let us know how things are workin !! Oh yea, no matter what pellet our how I run the stove, window won,t stay clear for more than a couple of days.

Tonight is the first night I've really been able to use the stove again. I have it on HR5 and the damper around an inch out and maybe I'm just imaging it but I swear the air I'm getting out of it is FAR hotter than it was with the damper wide open.

How exactly is the fuel regulated? As in, if I have the damper closed too much is it going to continue feeding pellets until it floods it self and goes out? Also, does it feed pellets until the heat exchanger hits a certain temperature and then back off?


Sorry if I'm asking a lot of questions, I tend to overanalyze things.
 
The fuel is regulated by your Heat setting ( H5 ). The higher the setting, the more fuel is burned. The more air is needed.
The damper setting has a lot to do with heat. Opened all the way, your heat may be just going out the flue. By closing it a little (like you did) you enable the hot air inside the stove to "soak" longer. Thereby extracting more heat. The stove does not know where you have the damper set. So if you have it opened a little and you are on a very high feed rate, then the pellets will not burn all the way and your pot will overflow.

The stove will run at the current settings until it runs out of fuel. The heat exchanger has no idea of the temperature of the air. The only way the stove will "back off" is if the stove gets hot enough to trip your high limit switch. In this case the stove will go into an auto shutdown for safety purposes.

Hope this helps.

Chris, Try it on HR 2 or 3 5 on my stove is for 20 deg. weather. Regardless yes, be careful not to put damper all the way in, it will fill the burn pot with pellets and will create a bad situation because the combustion will continue, there is not enough air to expel the ash and pellets will smolder over the burn pot.(my insert is lower than your stove and the damper can be hit with your foot when filling. My one son has a size 14 foot you guess what has happened) when you pull the burn pot out when cleaning, you'll see a v cut in the damper, to give a minimum air, but its not enough to keep the pot from over heating/ filling. It will take a few hours to overfill. I may put a clamp on my damper arm to alleviate the possibility of overfilling the pot again.

schoondog,


I ran the stove all night on HR5 and the burnpot looked good in the morning running with the damper around an inch out. First floor was mostly 68F and second floor was around 66F. House is 1700sqft of non-insulated 110 year old house with 24 original windows and it was only 38F outside lastnight.

I don't think I'll get by on HR5 when its 20F outside, if its windy out I have a feeling HR8 or 9 might barely cut it. Its not that 66F isn't warm enough for me, its more that our main bathroom is on the second floor and furthest from the stairs :)


By November the 150K btu input steam boiler should be working so hopefully I won't have anything to worry about.
 
Gotcha. Yea my home is smaller and insulated. 37deg. last night and mine was idling on HR 1. You need more. Well when you get your boiler done the stove on HR5-8 should do much of the heating though.

Beautiful day out, snowing 34F and dropping. Sadly the stove is at HR-8 currently and doesn't seem to be able to gain. I let the temperature drop to the low 60s lastnight and now struggling to bring it back up. The wind outside isn't helping it.

I was able to get more of the "HARDWOOD HEAT" pellets and they definately burn cleaner. Been going for 48 hours and the glass is 80% clear. I have also noticed she seems to burn much cleaner on anything HR5 and above, the higher the cleaner.

I am running the damper full out at HR8 because it seems to be best. Now sure how well we're going to do tmorrow night in the low 20s.
 
With the damper wide open you could be sending some of the needed heat out the vent. Heck with the clean glass, Get some heat where you need it. There has to be a happy medium or something.

Do you have back up heat to assist the pellet stove?
 
Judging by how its burning I have to guess the damper has to be wide open. The flames are easily 8+ inches tall. If I can close the damper more I'm all for it.

No backup heat yet. Natural gas line is suppose to be run within the next week and I hope to finish putting the new boiler together by next weekend. Tomorrows gonna be fun in the low 20s. :)
 
I think shes burning good with the damper wide open on HR8. What do you think?
