So my dryfit oven has been working nicely. It has a 4"+ perlcrete floor under firebrick (single layer all around, sailor course) with a dome height of about 12" and a door height of about 8". The side walls have 4" of rocwool insulation and the roof has 8". The insulation is covered with cosmetic dryfit paver bricks on the sides and a piece of durock on the top. Covered with ugly plastic when not in use until I figure out a better roof style. Anyway, I had an aluminum door made that has 8" of rocwool inside and I would like to know if it matters how the door should fit. I can place it one way where there will be about 1" of space between the door and the throat bricks (with 1/4" on each left and right side) or I can turn it onto its end and that will reduce the top gap down to about 1/4". Does it matter how well the door fits between the 2 options I have, obviously some air needs to get in to feed the fire. I also assume there are other ways for air to get in as this is a dryfit. Thanks in advance for your comments.
