Step #1 - Forget everything you know about burning wood.
Step #2 - Read, read, read.

Others with your exact stove will chime in with specifics but here's a few general things to remember. Coal likes to burn in a deep bed. So you must fill the fire box. Don't just put on a thin layer and think it will burn like wood. Coal wants its combustion air from under the fire, not above. Once the fire is going, coal does not want to be stirred and messed with like you might do with a wood fire. You've got to get the ash out from under the coal bed when reloading or it chokes off the air supply to the fire. Your stove has a shaker grate and handle for that purpose. Short choppy stokes with the handle or you will be dumping coal. Watch under the fire when using the shaker. You will start to see very small pieces of burning coal dropping and then the area under the fire will start to get brighter. That's as far as you go. Make sure your smoke pipe is screwed together. Handle the coal and ash carefully to avoid excessive dust. Have working CO detectors in your home. These are just a few things that come to mind. See Step #2.

Thank you for responding to my post. Hopefully, some more people will chime in with information on how to hook up the stove up. I need responses to all things needed to hook up the stove & get it running. Any help would be greatly appreciated.

b, do you have an existing chimney? hearth area? Some pix of stove & projected install area would be real helpful. coalkirk is real knowledgable with this particular stove-- ask him some specific questions---hookin it up is pretty vague ;)

Please correct me if i am incorrect but do you mean the SF 250 model? If so you have the beast of Harman hand fired freestanding stove. She will belt out some heat. As with any new coal burner please i say please purchase some quality carbon monoxide detectors. As fred stated please fill in the blanks for some of us such as chimney design and what you want your stove to accomplish. Lots of good info here, read read read as previously stated.

b, the same way you had the wood stove piped will work just fine but much less wear & tear on the black pipe as long as you do real good yearly maintenance :) I take it you have an 8" thimble going into the chimney? That's a pix of my wood stove in the rear of house--8" reducer coming out of stove & 8" expander??? LOL going into thimble--if I would put my hitzer back there I would use the same basics although the HITZER has a 6" outlet--so no reducer needed--just a T coming out of the back. I just use a MPD, not a Baro--one of the Baro guys can jump in here for all the new fangled stuff

first off welcome to the forum , it get a little slow this time of year here so it may take a while for some of us to get back with you

first off where are you located at? that helps with coal supply and you might have one of us right next door so you can see the install and how it burns,

my first stove was a sf 250, and would go back to one in a minute,

need location and pictures of where your installing it and condition of your chimney

you will need a barometric dampener with that stove ,

here is a link for the sf 250 manual it will have a install area in it


http://www.speedfreaksgarage.com/jeff/stove%20pdf%27s/SF250.pdf
This link is broken, either the page no longer exists or there is some other issue like a typo.


any other help just ask

Welcome to the forum. There is a wealth of info here and a little patience is needed as you go through the coal burning learning curve. Most all questions have been asked and answered already so using the search function will get you an answer quicker than posting and waiting.

But if you do post questions that have been asked a bunch of times nobody here flames you for not searching like a lot of forums will. its because the members here tend to be good natured, probably because we are so happy that we are saving tons of money and are keeping warm while doing it!! (and its easier than the wood burning most of us transitioned from).

Here is a pic of my barometric damper install. it is in the upper right corner of the pic. I have it in a 'T', the back side of the 'T' goes toward the thimble. I did it this way because I can thread a vacuum wand through the baro and clean out the fly ash in that horizontal run of flue pipe a couple times per year without shutting down.

Coal will produce fly ash that needs to be cleaned from horizontal surfaces periodically through the heating season. I clean mine about 2 - 3 times through the season and again at the end of the season. I am not familiar with your stove design but my harman mark III hand fed has a baffle plate at the top of the fire box where fly ash would accumulate and had to be cleaned when I cleaned the flue pipe. Otherwise it will hurt your draft and if blocked enough may cause CO issues in the house.

I recommend getting a manometer to connect to your flue pipe so you can measure your draft. It will help you set your baro properly and once you get used to the 'normal' clean readings for your setup can also be a gauge to help determine fly ash build up. If you go to the knowledge base in the very top bar you can get some info there or search for manometer and you will see many pics of installs. (same with barometric damper)

As others mentioned....get a couple CO alarms, kidde nighthawk digital read out is my recommendation. You should plan on getting another in about 2 years and then rotate in a new one about every 5 years to make sure you always have a newer working alarm.

What are your plans for coal storage...indoor or outdoor bin?

yes, a T out the back like fred's pic and a T at the top if you go with a baro as suggested. That is the exact setup i had with the mark III and it made mid season cleanouts easier. I didnt use a manual damper on my set upm it depends on your install whether it is necessary or not.

If you read through the damper threads there are two religions....baro and manual - And some even use both!! I don't think either is correct / incorrect but it depends on your stove / chimney draft / performance. Like i mentioned earlier, having a manometer helps put a number on the draft so you can monitor performance. If you do use both dampers make sure to put the manual closer to the stove in the flue than the baro.

No real need for the tee but you can put it in if you want. You will want to remove your stove pipe each summer anyway for a though cleaning and to protect you stove pipe from humidity. It needs to be stored away in a hot shed or attic in large plastic trash bags. Just don't store in a basement cellar type part of your house. The warm humidity will rust it very quickly.

Run 6" from your stove outlet to an 8" x 6" reducer. BUT wait till late Oct. Good Luck
