Valoriani baby 75?

[ilya_n]

I only put the one on mine and it barely gets the hose out while burner is centered, working well though and on day 2, starting to sweat now a tiny bit with temps around 400

Nice. Glad it’s working. Do you find that the dome spot right above it heats up significantly faster than the rest of the dome and especially the floor? Do you move the burner around?

I think it’s just a small enough diameter that no one runs long because of friction and pressure loss. You run as thick as possible before you have to downsize to what you actually need. I’m no plumber but with physics background so take it for what it’s worth lol

I’ve seen that longer black pipes start off 1/2 or 5/8”.

1/2”, 3/4”, 1”, 1 1/4”,  I have a 1 1/2”  feeding my 400k pool heater, I think I’m going to tap into that run with a 5 foot 1/2” extension to pop out through the wall that surrounds the equipment, from there I’ll just use a 1/2” flex line with quick disconnects to hook up the oven.

The problem with residential gas lines needing to be so large is that while you may have a 1/2" poly line feeding your meter at 40 psi that's capable of delivering over 1,000,000 btu, after the meter it is regulated down to approx. 1/3 psi so just to feed a tankless water heater with a max 199,000 btu on the average run you need 1" to 1 1/4" pipe, SoCal Gas (and others I'm sure) have started a program with new construction where you can apply to run 2 psi pressures in the home so these ridiculously oversized (and expensive) gas runs can be down sized.

Yes it hits a 100 degrees higher than high up on the back wall, I’m just leaving it centered and I’m doing 10 min  at a time with 20 min or so off in between with the door closed to let it saturate with heat better

Very nice. It should do the trick.

Been slowly curing the oven.

Day 1, 5 hours maxed at 300
Day 2, 6 hours maxed at 400
Day 3, 9 hours with small steady flame now and max dome temp 480

On day 2 started noticing water dripping, closed the oven door at 11pm with 380 dome temp and 11am it was still 175 with a bit of water coming out all night long

On day 3 its been steadily draining now all day, just drips but adding up to a bit, even after 9 hours it has not slowed down

I am afraid to raise temps tomorrow as I think it should slow on the seepage first, I think? never had an oven before so not sure.

[ilya_n]

As they say, slow and steady is much better. Repeat the previous day temp for a few hours.

I always stay low and slow till dripping stops.  It can sometimes take a week at 24 hours a day for my big boys!   better safe than sorry (cracked!)

So under 500 is safe? I'm using that small flame on constant in the last pic now and the very top of dome is at about 525 while 4 to 5 inches off center is in the 460 to 480 range, its only the center 5 to 6" circle that hits over 500.

If you search for 3/8 black pipe on the Home Depot web site, they have nipples in 6" increments from 6" to at least 36" and I would also suggest putting an elbow at the end so the hose goes straight down and is more out of the way. Thought if the burner is only to season it, I guess none of that matters.

Yeah just for curing, I was just going by what was available in store and noticed that the plumbing supply houses did not even carry 3/8", Home Depot only has up to 6" nipples in my area so that worked for this purpose.

I think you will be fine as long as flame is not large.  Thats only 460 on the surface.

Day 1, 5 hours maxed at 300
Day 2, 6 hours maxed at 400
Day 3, 9 hours with small steady flame now and max dome temp 480
Day 4, rained out but I covered with a tarp first just to make sure I did not take a step back
Day 5, went 30 hours straight into day 6 at the same 480 to maybe 500 dome temp measured at 4 to 5" off center
Day 6, noticed water was barely dripping so turned up the heat with about 100f bump, few hours later another bump and getting to 650-680 range
after another 10 hours water back to dripping more like earlier, man this thing wont quit! and my wife says I have no patience, PLEASE!

You have no patience
Keep going at the same range as the last one before it stops dripping and then some. Bump up when you are in the clear.

[scott r]

im sure your getting close... no problem curing 24 hours a day now.  It will eventually stop.   again... what an oven... wow!

I see you are on her side! Haha, it is slowing a little and still holding in the upper 600’s 4 to 5” out from center of the dome

I hope so, I promised to make pizza for 12 people Friday night, well if we get rid of all the moisture by then that is

Nice! Finally got my SC80 today!!! Yay!

When you were curing with the burner, and say on day one you were keeping 300F for 5 hours, do you recall the temp of the floor? I've tried keeping the top of the dome around 150C and the floor is roughly around 40. I know it'll get much warmer when I get to higher temps but just thinking if I should do it differently somehow...

Sweet! that one was really the only other option on my list and not available with gas for months so that was a good score for you, when I first started at 150c the floor was only 40c for a couple of hours but soon warmed up to about 60c,  I had the cover in place with a 1" gap for the hose and small amount of air, I ran the burner for 10 to 15 min at a time, pulled it out and closed up the door for 15 to 20 min, had to repeat that for a while as I could not leave the burner on or the oven would get too hot, after about 3 to 4 hours I was able to get temp a little bit higher and the floor started heating up to 200f to 240f while top of dome at about 400f

[GilScales]

So i'm on day 7 and flame has been on since day 5 with steady increase in temps, top of dome well past 800f and 4 to 5" off center at 750f, floor temps up to 550f with bottom edge of dome at floor around 450f to 500f, this thing just won't stop dripping!

The curing instructions from Mugnaini is saying a 2 day cure with day one a 4 hour cure to max 300f with a 50 to 70 degree rise per hour
Day 2 says warm up for 15 min then start where you left off with a 4 - 6 hour cure raising temps at the same 50 to 70 an hour until you reach 650 to 700 floor temp in center.

Valoriani's curing schedule is a constant 2 day cure with 100c to 150c first day and on the second day raise temps about 50c every 4 hours until dome starts to whiten and then you are done.

Both of these seem way too aggressive compared to what I'm seeing with all of this water coming out, gotta be over a gallon by now!

Wow... you can start making NY style pizzas while curing at these temps
Did you connect the gas line yet?
