last year i bought a house and it had a wood stove hooked to masonry chimney. after 1 season of that nonsense im thinking about switching to a rice coal stoker stove. can i just hook that right to the exsisting masonry chimney? i see all these options power vent and direct vent. I just want to make sure i do it right and safe. any help would be great.

Using a masonry chimney is the preferred way, provide it is in good shape. An interior chimney would be best.

You're in good shape with a masonry chimney! :D

If you thought burning wood was nonsense be glad you don't need any power-vent or direct-vent! :baby:

NO! A masonry chimney needs no metal liner, no matter what your chimney sweep tells you.

The best way to vent a coal heating appliance is with a regular, old fashion, masonry chimney. No metal liners, no power vents, no direct vents, just natural draft from the chimney you already have is the best thing.

With a coal stove, the masonry chimney hardly ever needs cleaning. You will have to clean the stove pipe once in a while.

Regular black stove pipe is all that is needed to connect the stove to the chimney. Make sure it has the proper clearance to combustibles and put 3 screws in each joint.

The coal stove will dry out all the creosote in your chimney and it will begin flaking off. If the chimney is reasonably clean I would plan on cleaning it in the spring after your first coal-fired winter. If the chimney hasn't been cleaned in a while, it would probably be best to have it cleaned before you fire up the coal stove.

Most people use single wall black pipe between the stove and chimney. Some of the old timers like my FIL still use galvanized for stoker boilers. SS will work but probably won't blend in as well as black pipe.

Make sure the chimney is cleaned. It doesn't have to be perfect but if there is a lot of creosote buildup you want to try and remove it. Two issues.... firstly coal will "dry out" the creosote and it will eventually fall off potentially blocking the flue. There has been posts in the past of people reporting very large sheets of it falling off. Secondly if the creosote is still present a chimney fire can still occur, if you have a barometric damper which is standard for coal stoker you now have a chimney fire on steroids.

Once the creosote is removed there is of course no possibility of a chimney fire.

You don't need a liner IN it. You DO need to run your pipe up past the chimney damper plate and seal around it.

so I'm gonna reopen fully, sweep it, but without liner in it I'm really surprised i find it very risky

but i got one More question.

i désire to burn both coal and wood..
so for coal you are saying no liner inside the chimney.
but for wood i would need a liner in it right?
so if i burn both it's better to line the chimney, (i'm not gonna take on and take off all the time) if so, do i have to use à 3.14" pipe and liner same as my stove exhaust or do i have to put an adaptator and go on 6" liner?

No liner in chimney for either. You do have to get your pipe up into chimney past the chimney damper. We're you able to.do that?
