QUESTION on the FB vent openings......
Where should they be placed in relation to the fire grate - even with, below, above?
I'm guessing if the vents are too low then ash and coals might fall out. Too high and intake air doesn't hit the fire.
I'm thinking that since the bottom of the grate is 4" then the bottom of the vent should be 4" as well.
Any other theories or advice out there?
I put my vent openings right at the fire grate level (about 1/4" above if you want to get technical). Works great for me.
As Dave always suggests, make sure you add a small vent in the FB directly across from your FB/CC opening. The vent helps pull air evenly into the CC. Mine is 3"x3" and we have about the same size FB & CC.
