The SS box on the front is supposed to be a warming box, the old wood stove on the back is the FB.Edna's Kid wrote:Maybe I'm looking at a warming cabinet...? Picture 1 has me thinking I might be...

I am thinking that the firebox is on the back since its not a RF and the stack is at the opposite end. Then the box at the front with the piano hinge is a storage box.
Yes that is correct
If thats right, heres my take on things.
First off, I would check and see just how close the numbers are for the firebox you have. FB size recommended 21175.0 c/in
FB size at this time 10766.25 c/in
50.8% too small
If there close at all, I would stay with that firebox.
Turning it 90 degrees and dropping it down so that the bottom was about 8 inchs off the ground.
I would cut the rear cross member and brace it back to the second cross member. If the firebox is heavy wall then I would weld the frame right to it. If its cast then I would cut a section, drop it and make a support for the box to sit on. Like a cradle. It's thin metal with fire brick inside
I would go with a full reverse flow to take full advantage of the radiant heat values.
Tuning plates could possibly work for this rig but I would want to go with a full size firebox. Keep in mind that most of the calcs I have seen are set up for Reverse Flow.
I am with Franks thinking on the specs that you are close but with out running the numbers myself its had to make a good guess on the stack end of things.
As said I would go full RF, meaning that the stack has to move to the firebox end.
On the air intake, I'm not sure which way I would go without seeing the available space. Either 2 smaller round vents or 1 thats around 10 inchs.
When you ran the numbers for the air intake, did you calculate the full circle? I'm thinking, Yes. Only because thats how most calcs do it. Yes full circle
When it says you need say 1 round vent thats 8 inchs, then you need to look at the square inchs and then do the math for the butterfly shape that will actually be the openings. Been there done that, is the only reason I know. My thought was a full circle with a plate on the end of it that with a center screw could move in and out.
My 16"x42" rf with a 20" long firebox needed 1 butterfly vent that was almost 8 inchs. Since you won't get the full area for air flow.
You could maybe use rectangle sliding vents and make it work tho.
No problem get on the soapbox anytime if you see me going in the wrong direction. I've already made mistakes as you can see and would not like to repeat things again.Rick wrote:Yeah you can type that DC - I've been called worse!
And grabber, I always look at the few bucks to get it calced dead-on as insurance against the big bucks to get her built.
After 15 weeks of nights, weekends, and dollars building Edgar, the first time I lit him it was 28 degrees outside and freezing rain. In about an hour he was holding 238 degrees.
A lot of the other addicts on this site will confirm - THAT is a great feeling!
And now I will get off my soapbox... sorry
