coal stove stopped venting outside

PostBy: M1KEMASS On: Sun Nov 02, 2008 12:15 am

I got a bad bag of coal, but I decided to try it anyway - against my better judgement. My stove uses pea coal, and there was "coal sand" at the bottom of the bag. Anyway, the fire went out in about 20 minutes and after a few hours of it cooling down - I cleaned the stove out. Now when I try to light the starter fire - all the smoke comes into the house. I guess I'll have to disconnect the stove and see what's going on. Does anyone have any ideas?

Was the chimney in the past used for burning wood?? If so, some large pieces of creosote came off the inside of the chimney, fell down and now block the chimney.

Could you have a reversed draft because everything has been allowed to cool? Use a hair dryer or heat gun to force some hot air up the chimney to try to get it warmed up and draft in the proper direction and relight the stove again.

This is a newly installed used stove - I used a full stainless steel liner up the chimney (after it was cleaned) and caped with the chimney cap it came with it. I'm not sure about reverse draft, but I know the smoke would not go out of the stove except through the air inlet at the bottom of the stove. I just had the windows opened for about an hour to clear the smoke out (not so comfortable on a 32 degree night. I'm going to bed and will see what the draft is like in the morning.

You could try Gamblers idea of getting the chimney heated up right now just to see if that's it.
If that is the problem it will start drafting immediately.

Anthracite coal should not give off any smoke are you sure that bag of coal is Anthracite Or could it be Bituminous coal
soft coal will throw off alot of smoke when it starts to burn Plus you need some over the top air to burn Bit coal
and being you said the fire went out right after you put the coal on that makes me think it could be bit coal

It was the wood fire before adding the coal that smoked the house - not the coal.

Did you install an insulated liner? It sounds like your flue is just cold. Need to get a draft started. A piece or two of newspaper placed strategically at the vent out of the stove and lit will often do the trick.

Also check to see that nothing is blocking your chimney or liner. (bird's nest, animal, whatever)

(If there is, go up on your roof with a cloth bag with some rocks in it & tie a rope to it. Lower it all the way down your chimney to clear any blockages)

I second Coalkirk. He is right on here. I get the smoke too until things get heated up. Use some newspaper just before you start a wood fire prior to your coal fire.

If your house is tight any exhaust fan or clothes dryer that is running will cause a back draft

If you have a down draft the chimney is probably not clogged - i.e. if the smoke blows
out into the room. If you have no draft then somehow the chimney got clogged. I agree
with the previous post - use a hair dryer - stick it as far up the stack as you can and let
it blow hot air up the chimney for a couple of minutes, then quickly light a piece of newpaper
and hold it close to the outlet and it should draw the smoke up. The newspaper will also
give off a lot of heat which should get/keep the draft moving in the right direction. Then
get your fire going. I used to have a stove in my basement that had such a down draft when
cold there was no possible way to get the updraft going without the hair dryer...

Thanks guys - there was an exhaust fan on - which has never caused problems in the past - but has also probably never been on when I was trying to start the stove. I started the stove around 5 this afternoon, and it's burning with no problems. Thanks for you help.

Tell us about the exhaust fan. Was it a kitchen or bathroom fan??

I've read that large kitchen fans can be a problem but I've never talked with someone who actually had this problem.

Newer tighter homes with power venters can cause the same on a marginal draft chimney. We also have had clients complaining to oil guy the house smells like fuel oil. A 1200 cfm DCS hood over the 48 inch range was the culprit.
Client learned to open the window till a fresh air set up was done for the boiler room. She still uses the window as we showed her, which makes the hood work better than it ever had.
WATCH THE POWER VENTERS EVERYONE
Make sure you are feeding them enough air!
