I have a Gatling woodstove rear draft just like the one in the picture I posted I’ve been using it four years now where I blocked off my fireplace and go out through my 12 inch terra-cotta pipe works wonderful. The gentleman I got it from bought it new and said he used to burn coal in it for years with no problem. I’ve only burnt wood. I can’t find any specs on this. It is fire brick lined in the bottom. Is it capable of burning wood and coal safely does anyone have any information on the stove?
