The Care and Feeding of a Warm Morning Stove

Just found you all while looking for info on my Warm Morning 520. Working on getting a chimney pipe adapter to go from 10x3.5 oval to 6" round. Pics to come

Looking fwd to pix.

I took a 7 inch piece of pipe and with a little bit of work and frustration you can get it down over the oval hole then adapt it down to 6 inch

Here are pic of my WM. The guy on craigslist wanted $250 and I walked away with it for $100. The lid was broken in half and he had it brazed together. The hinges are busted too. I see the grate is in less than perfect condition but I think it will do the job for my wood burning. I had a little air tight wood stove for my 2 car garage, but it was too small. I was planning on fitting a pipe INSIDE the WM opening.
Hope these bricks are in good enough condition.

Does anyone know where an 818 falls size wise? It's jacketed, but I can't find any info on what the coal capacity or rough BTU's are on this particular Warm Morning. Thanks.

I have an 818 and the capacity is 40#. I know the 616 is 60#. Maybe the 818 is 80#? Is it jacketed like the 400 series? I love those old Warm Mornings.

I have always thought the Warm Morning is a clever bit of design engineering.

The claim is it turns coal into coke then burns it. In studying it, it seems to me that this is how it works:

The central mass of coal is in effect a hopper. The negative draft over the coal has an easier path through the brick chimneys rather than through the thick and deep bed of coal. This will tend to have the effect of drawing volatiles down through the coal bed where it meets the burn area and the primary air and burns there, exhausting through the corner flues.

It's jacketed, but it's tall and skinny instead of squat like the 400:
**Broken Link(s) Removed** I'd rather have a 400, but dang, this one looks pretty nice. If it's less than an 80 lb stove I fear it will be too small for me. I hate to give up my bi-metallic thermostat if the 818 doesn't have one like the 400?

franco, these warm morning stoves basically use the brick tubes in the corners as a way to preheat the secondary (derived in this case from the same source as the primary) combustion air allowing it to be heated without the use of short-lived metal tubing. It's a nice design. If the air was drawn through the fuelbed in a downdraft situation and then up through the corner tubes the grates would fail very, very quickly.

I don't think that stove is jacketed. I think it just has that shiny enamel type finish that the 400's have. Nice looking stove. The main thing is that the corner bricks be in good shape. They're expensive, if you can find them.

It seems to me any downdraft would cease at the upper opening of the corner chimneys, well above the grate.

I just had an oval to round adapter custom made and I installed a 6" damper (pic). I am looking forward to using the stove for my first time. While examining My Warm Morning 520 I noticed that the bottom of the fire box (below the grate and ash pan) seems to be made of very thin metal.

What is the bottom of your WM stoves made of?

It seems to me that the bottom should be cast iron or should be lined with firebricks. I plan to burn wood because that's what's available to me. I'm worried about burning through the base!

Does anyone know the capacity of a Model 500? It's square, large jacketed, but I have only seen photos so far so I'm uncertain if it has a bimetal thermostat or not. Thanks for the help.

I have had the most luck searching google news archives for old ads.

Says in the link the 500 holds 80 lbs....not sure about the thermostat though.

Someone asked about the 818 up the thread. Thats what I recently bought. It holds 100 lbs. If anyone has an extra door for this model I am going to try to put glass in one and I would like a spare to play with.

Thanks for the info and the search tip! I can't get it to move down on the stove ads, but the info was what I needed anyway. I posted about your 818 a few posts up.
