starting a new build would appreciate any info

[dstiltz]

I am starting a new build. It's a 5ft propane with a 24" diameter. The Firefox is going to be 24-24-18deep . I have a couple questions on where the door should go , the Firefox air intake ,and where should the stack go? I ran some numbers on the calculator. It's going to have 4" chimney that should be 41 " . Is it better to put the chimney right on top or should it go on the side grate level? The fb to cc suppose to have a 83 cubic in opening . Will 16-7 half moon work?

is a calculating tutorial for you to look at....   I would use the plenum exhaust starting at grate level.... 

461 cu. in. exhaust.......  4" X 37" tall....   41" height would work....

Is it best mount the Firefox on the tank so it is easier to weld on the bottom before you putt legs ? Then cut the hole to the cc. I did learn a trick on cutting the lid, used skill saw with metal blade . Instead of cutting all the way in and then following the line , it worked better by cutting the grove and just following the grove on top and go back and forward till you cut through. I was surprised we only used 2 blades to cut lid. Took about 2 hrs to cut .

I was going to put a upper grate in cc. How far up do most people put their grates?

 

[dstiltz]

The opening from fb to cc should it be what the calculator suggests or is bigger ok and if you go bigger is there a rule by how much?
