Depth of FB into CC

Post by Newsmoke » June 24th, 2019, 3:22 pm

Dear All,

Every build i have new questions! I'm planning to have the throat of fb at 2.6 inch below the grate for my 132 gallons tank.
At which depth in the CC should I install the throat?

I'm not exactly sure what you're asking but the throat needs to be at the highest point on the side of the FB and I like to keep it as low as possible on the end of the CC. Don't forget that you'll need to leave a 1'' grease dam at the throat to keep the grease out of the FB.

That's a good question and not one that's been asked often...

My 2 cents...no more than is needed to marry the firebox to the cook chamber. If it is nested too far under you'll get a real bad hot spot on that side of the cook chamber. You'll already have one without any overlap at all which more and more folks are combating with a shadow plate.

Good luck!

Yes, yes....put in a shadow plate. I didn’t during the build and then faced some real challenges adding it later.

Thanks a lot for your insight, For the shadow plate I intend to put a plate at grate level that will be drilled a little on top of which I will put my water pan.

I have experimented with shadow plates quite a bit. I found that one mounted above the baffle plate is not nearly as effective as one below it. My current setup is 1 inch ceramic insulation between 2 pieces of 0.25 plate and mounted below the baffle plate. Pretty extreme but it works incredibly to keep my temps even and all but eliminated the hot spot on the firebox end.

Nope...lol.

I had to size it to fit thru the throatand then blindly wiggle it in with one hand, wedge it in place and tack it. No way a picture is going to be of any use now that it is covered in black smoke. I’m happy to answer any questions you might have tho.
