fire box size reduction

PostBy: AlmostThere On: Sun Feb 16, 2014 11:08 pm

I want to reduce the size of my fire box in my ds machines basement #4. It currently works great in my house but I will be moving to a house that is smaller. I'm not interested in buying another stove simply bc I like this one. So here I my question. Should I design and build a steel box to take up the extra space or just find fire brick that will lay across the grates. I'm sure this has been done before. Any suggestions. The house I will be moving to as mentioned is much smaller. The stove will be located in the basement. The total house sq footage including basement is 1100 which is way under the specs for this stove. I'm thinking of dropping th firebox size to 16 X 16 from the current size of 16 X 24. I should save coal!!!! Thoughts?

Hi fellow coal burner, Mike here in the beautiful state of Maine. Vigilpeaburner has an excellent short video for a smaller fire box. A different stove, but I think you can gain some great info. Good luck with the move and your project!

why not call Amos at DSM and see if they offer anything or if they can make something.I reduce my firebox with 6&8" cement blocks,but I have a much larger boiler,then throw away the blocks in the spring.

The usual problem is to have enough space for the grates to shake without disturbing the bricks. Bricks will have to be raised at the bottom about 1 inch to let the grates shake normally. That one inch gap at the bottom should not make a difference as long as the space behind the brick is sealed at the top.

My Hitzer 983 had 3 separate shaker grates. I'd let one or two of them ash up by not shaking. Just added coal to the remaining grates and shook those normally. Worked great when the weather was only cool outside.

With a reduced firebox, but same surface area of the stove to absorb and radiate the heat, you will presumably be running a significantly lower flue temperature. Make sure your new chimney can still provide adequate draft. What size coal do you burn? I wonder if you could just burn pea, and let the stove idle most of the time without monkeying with the firebox size?

That is a really small square footage, especially if the basement is insulated. Will you be heating the basement, or is your true heating need only 550 square feet? Where are you located? I know you like your stove, but a smaller one might be more practical.
