I'll see if I can figure out how to post a picture.

If it's only a few rooms then it should be sufficient. I've known a few people that have had them and all have had trouble with them as far as overfiring and ruining the plate that seperates the coal and fire.
The ones I have seen have a vertical plate going from one side to the other on the inside. Behind the plate is where you put the coal and feeds by gravitity onto the grates.
I'm just giving you fair warning because I've already seen a few of them get ruined.
