Re: First Fires in the Nightmare Build - long
After the teleconference with Forno Bravo, the oven will be stripped down to the base, top cap reset, exterior inspected and remortared, and at least 4 inches of insulation blanket installed over the dome.
Additional photos wil be sent of the hidden portion of the build so they can inspect the concrete base and foam board under the floor.
Will the mason be able to pull it off? We shall see. He has a large financial incentive from the builder.
I am at 5 months of the build. My last house took less time. That was only a 1900 sqft brick ranch - nothing as complicated as a kit pizza oven with available video instructions.

Re: First Fires in the Nightmare Build - long
Aftert talking to Forno Bravo and emailing them pictures of the build, and then talking to their production engineer(Sam, I believe), he and Maria told me to stop curing the oven. Sam's words were "bad build". No kidding
Insufficient insulation blanket, bad cap on the dome were the two things he mentioned. I called the builder and told him that don't take my word, take the manufacturers. Allegedly all photos of the build have now been sent to the production manager by the mason and they will have a teleconference tomorrow morning that I have been invited to attend. I will be thereto make sure the conversation covers ALL design concerns.
I am not worried about being left in the lurch. My wife sleeps with a trial lawyer with 25 years of experience. I am most concerned that when/if this goes final bad, I have ensured he has had every opportunity to cure his failures. After being a trial judge, I have learned the art of patience and allowing one to hang themselves.
In the end, if the current guy can do it, great. If he can't? I have a contract, a warranty, and a trial lawyer with far too much time on his hands and who is rabid on the issue. : ). I will have the oven I bargained for at the price I bargained for. The rest of the guys work is wonderful according to another mason who did some unrelated work on the house. This? We shall see.

-Only partially replacing the plywood floor (in front) and then replacing it on the last rebuild
-Not having the oven square on the platform.
- Additionally I was told by the mason FB did not sending the correct floor causing the door not to fit.
At 337 degrees inner dome temp, the outside stucco was 120 degrees. Is this normal or is there insufficient insulation on the dome? At full heat, it would seem the outside would be over 600 degrees.
I see some what looks like hairline cracks on the inside of the oven dome (lower part, not at the peak) that developed today (today's was even a lower heat than yesterday). People say don't worry about cracks, is that inside or outside cracks or both?
I see major water spots on the stucco. I cannot say if the insulation was installed dry or wet. The insulation was exposed to the elements. Is this a dome issue or potentially an insulation issue.
I lost faith in the mason long ago and wish my builder would use a different mason and start from scratch, but as always it is a money thing (not for me, I have paid for an installed oven). In the end, I don't care who builds it, I just want it right and somewhat soon, I closed on the house in July.

Re: First Fires in the Nightmare Build - long
The floor looks to have rather wide mortar gaps between the sections. If so that would be incorrect, and would explain why the mason thought the floor was wrong.

Re: First Fires in the Nightmare Build - long
Generally, if someone builds something wrong, I will try and help them figure out how to make it work.
However, when money changes hands to build something, it should be done right. Make them take it down and do it right, including a properly sized base. The FB instructions are simple, as is the general construction of a pre-cast dome oven.

Re: First Fires in the Nightmare Build - long
so sorry to hear of your troubles!!
My oven is built from scratch using firebrick, but like Kenny, when I am at 1000 degrees inside the oven I have never seen above 100 degrees on the roof above the insulation, so I tend to agree that there is likely an insulation problem.
Good luck!

When things go like this from the start, expect to always have problems with your project. They should make it right, not hope for the best....until you are standing there watching their taillights going down the driveway.

Third fire went well until the end. I had no weeping of the stucco until the flames went out and was allowing the fire to die. My handy analog thermometer next to the fire was at 350 and the weeping began and the dome was 121 on the outside.
I plan to call FB today about the top heat today

First, let me say that I am a novice builder & will let the experts chime in on this as well. I do however own a Professionale 120 (48" hearth) that I attached to a trailer so I have some minimal build experience.
I can tell you that after my curing fires, and having my oven up to 900F-1000F my outside dome on a hot Florida day (90F) registers around 98F which is mostly from the sun heating the dome up and not the fire inside. My belief is that either your insulation under the stucco may be compromised or the mortar joints are defective which has allowed moisture up through the stucco in the one picture.
As far as cracks (inside or outside), my rig which has traveled on the road to at least 10 events with around 100 miles of travel all with a hot oven, show very little to zero hairline cracking externally and minimal cracking internally.
Another area or possible issue could be the stucco as well.
Hope this helps. If you are having issues at low temps then my suggestion before major damage is done is to contact FB and see what they say. You might have to deconstruct your build and start over with new mortar on your joints & fresh insulation & stucco. It really is hard to find not "good" help these days but competent help these days.
Sorry to hear about the shoddy workmanship.
Best,
Kenny

First Fires in the Nightmare Build - long
I have finally started the first small fires in my nightmare build.
My oven is part of my new house build, a Premio2G 110. I was out of town when they did build 1.0 in August so I have no idea what the dome insulation is.
The mason contractor had not built a FB kit before, but has claimed to have built pizza ovens before. His masons did not read the instructions which resulted in (among other things):
-A platform too small for the oven (first picture).
-The fire brick and insulation sitting on plywood floor
-Only partially replacing the plywood floor (in front) and then replacing it on the last rebuild
-Not having the oven square on the platform.
- Additionally I was told by the mason FB did not sending the correct floor causing the door not to fit.
The dome has been moved and slid around at least 3 times. I am concerned that the mortar lost its integrity as well as the dome itself. The mason has now said he has done everything to FB specs and has documented it with pictures (I do not have them). The oven has been done for a month.
All of that as background, I have fired the first two fires and see potentially trouble brewing. I kept the fires low (I think I attached a picture of the fire), and the oven thermometer I have next to the fire never went above 320 degrees although the flames would lick up and get where it would touch to 400-500 with a laser thermometer, but I knocked the fire down and the heat would quickly go back down. I spread the coals out to try and get an even heat. I kept it up for 4 hours each day. I did not try and bump up to 350 but tried for 2 300 degree fires.
Here are my questions:
At 337 degrees inner dome temp, the outside stucco was 120 degrees. Is this normal or is there insufficient insulation on the dome? At full heat, it would seem the outside would be over 600 degrees.
I see some what looks like hairline cracks on the inside of the oven dome (lower part, not at the peak) that developed today (today's was even a lower heat than yesterday). People say don't worry about cracks, is that inside or outside cracks or both?
I see major water spots on the stucco. I cannot say if the insulation was installed dry or wet. The insulation was exposed to the elements. Is this a dome issue or potentially an insulation issue. I have attached pictures .
I lost faith in the mason long ago and wish my builder would use a different mason and start from scratch, but as always it is a money thing (not for me, I have paid for an installed oven). In the end, I don't care who builds it, I just want it right and somewhat soon, I closed on the house in July.
