Would someone be willing to take a look at mine Ave ten me why the smoke is coming out of the feed tube?

No, I did not know I needed to. The paper caught just fine, check it out here: https://youtu.be/WMxx-VuU4VA

Can you help me? Testing my build and smoke comes out the feeder. Riser is curing, but wanted to test a burn with some newspaper before I weld on the rest of the tank.

All is 6 inch round ducts. The feeder and burn are thick steel. The riser has no metal, it's a mix of 7 parts vermeculite, 7 parts perlite, 4 sand, 2 mortar cement. It's only a day old in this video, so it's not cured, but it should burn properly, I think.

Riser is double the burn and double the feed tube in length, all 6 inch. I read above that the feeder should be 1/3 the riser so I'll shorten it and try again.

Please see picture and help!

Im I'm sorry but I'm still confused on how to make the heat riser. I thought I wasn't supposed to use metal, but one of you said I need to use steel as a liner and someone else said fire brick,someone el se said you don't want any metal inside by the heat riser.

Is there not a cut and dry way to make the inside heat riser using perlite clay?

Firebrick would be difficult because it seems like it would fall apart since it's just bricks on top of each other.

What diameters should the heat riser be? 4" inside/8" out, 4 in/10 out, 6/10, or 6/12?

How do I make the vermiculite/perlite clay slip? Can someone tell me ratios and ingredients? Is perlite or vermiculite better? It still seems odd to me that it is going to be solid enough to withstand that much heat and not burn/melt/crumble.

Ok, so from all the info you given me (which is awesome), I've drawn a design on how I think best to build it. Please take a look.

I've written questions on it, I'd love for you to answer. Anything that looks wrong or improvable, please let me know.

This is one of the coolest forums I've ever joined. So glad so many are willing to help!

Yes, I'm trying to heat a small 2 bedroom home, no cooking, and no mass around the exhaust. I live in the sw USA. Fire brick would not work because the propane tank that surrounds the chimney is only 14 in.

So in Kurt's video he has steel iner pipe I surrounded by about 2 inches maybe 3 of inflation which of those I'm guessing is like that Clay slip with vermiculite or perlite and then he has another pipe around it. that is the same as what I was trying to do, but you're saying not to. I think what you're trying to say that it's better just to have the insulation alone and not have a pipe on the inside or the outside? In order to do so, what you use chimney duct pipe say 6 inch and 10 inch and then fill in the in between with the vermiculite or perlite clay and then once it's hardened remove the metal piping and just use the hardened insulation as the chimney/ heat riser?

If you can't make the internal chimney with metal pipe, what should it be made with then? All videos I've seen on how to make all hace metal chimney's. I'm trying to make this type:https://youtu.be/UBWSNjvO4cc
