Anybody familiar with these units? i plan on using a masonry chimney, but i see one member here has his direct vented and had problems with draft. just curious what people think about dirct vent and what kind of venting system used.
Also, my chimney will be roughly 12-14 feet high it will be located at the back of the garage. i'm wondering if that height of chimney will be adequate for draft since the total chimney will be 12-14 ft hight but the inlet from the garage will be a little less than half way up at it's entry point> thanks

I think your planned chimney should be tall enough, although it sounds marginal.
The stoker type stoves and boilers don't have to have as much draft since the fire has a combustion blower forcing air through the coal fire instead of the draft drawing air through the fire.

You may get some smell when the door is opened to get the ashpan out, since the draft may be minimal, but since you are in the garage it shouldn't be a huge issue.

A K6 will be a nice unit to heat your floor.

Field Controls sells a "Draft Inducer" product that can be used to solve any draft problems with a short chimney. It specified for use with coal. It is not a through the wall type product and you must have some sort of standard vertical chimney. I don't have any experience with the product. Product info at:

I second what Greg said. 12-14 ft is marginal, but should work, especially if it is a Class A chimney (insulated).
