After reading all the pages here and the many repete questions and horse hooy Ive made up my mind with out even touching a unit.
The ash removal has made up my mind not to buy this unit. I have put up with a add on furnace for 28 years that had slits you poked the ash thru to get to the pan. It was such a time comsuming job not to mention a royal pain I just let the fire die down and used a old round shovel to take the ashes out the same way the wood went in. Then use a little square ash shovel I modified to finish it up.
I'll take the less efficent furnace with a shaker grate to replace what I have.
