A typical hand fired stove needs .05"-.07" to burn well.

Since you burn wood in your stove, have the chimney cleaned and inspected,, it may be full of creosote.. Make sure the cleanout door at the bottom of the chimney is closed and sealed.. caulk it if necessary.

You need a lot more draft than .01 to pull combustion air through your coal fire.

Remove the probe from the chimney, or the tube from the Dwyer Manometer, and let it sit for a minute,, then reset the meter's 'zero' if needed, hook up again.. the zero often changes with temperature..

Try burning it with the window cracked. If that solves the problem, then you'll have to figure out what is required to solve that problem.

An open cleanout door is like a stuck-open barometric damper,, it drops the draft to near zero.

Glad to hear you had the chimney cleaned..

Is there any other appliances connected to this flue, or an old thimble or flue entrance in the basement that isn't sealed up?
It seems like air may be getting in to the chimney from someplace other than through the stove.

The draft may be 0 when the chimney is cold,, it needs hot air in the chimney to create draft.. Once you have a fire established, then it should be .05" or more.
Keeping enough heat in the chimney to creat a draft, without burning the stove too hot and fast is the balancing act you must learn and perfect for your stove and chimney.

Sounds like you need to keep a hotter fire going to keep the chimney drawing.

thanks for your help I got a fire going today and it seems to be going alot better. I got the stove alot hotter this time before I added coal. Draft has been staying good as long as stove temp stays up.

This balancing act to maintain a good draft is fairly easy when it is cold out, you need more heat so you burn the stove hotter, but when the weather is mild, you desire less heat, but the chimney needs more, not less heat.. so you have to allow the stove to burn hot, and just open a window or two to keep the house comfortable... Otherwise the chimney will cool, the draft drop too low and the fire goes out...

Sounds like you have it figured out.. every instalation, stove and chimney is different..

Stove has been running great just trying to perfect the whole shake down process but it has been keeping the house very warm with 40* days and low 30* nights. Ive been reading past post about dampeners and unfortunatly I don't have room for a baro only a mdp, and am trying to figure out what the draft should be (on a manometer) once the chimney is heated and have a good fire going. The guy where I get my coal from told me to close it all the way and from what ive read on here that is dangerous.

It really depends on the chimney. Since you seem to have draft problems with a cool chimney, I'd hesitate to close off a manual damper too far, it may cool down the chimney too far. If you put a probe thermometer or even a magnetic on/in the flue, you can monitor temps as well as the draft..

Just be careful about choking it too much, you can kill your fire with too little heat in the flue. This is why I like the Barometric dampers.. the flue is unobstructed, and it only opens when the draft is excessive.

I have the manetic thermometer so what should I look for for numbers? I am just trying to figure out if I am wasting heat going out the chimney with the mdp open. If I run the stove normaly with the draft open I get about .05 or higher depending how hot I am running it and if I close the mdp the draft drops to about .02.
