Hey Danny,
I know a lot about this situation and the oven, and everything you have said sounds right to me. Basically, you are in great shape.
On the details:
1. Yes, we provide commerical length tools. Our premium tool line has 59" handles, and there are placing peels, turning peels, a brush, rake and shovel. You're lucky, the tools that come with the oven when you buy it new are really cruddy, so you'll be in better shape. Our tool producer is the biggest in Italy.
2. You don't need to insulate the oven. It's done. If you were to cook really hard with it commerically, you might get some heat in the enclosure -- which is what Peter in LA is seeing with his Italian made (different company) oven. He has beefed up the insulation using Insulfrax and SuperIsol from us. But for you home, you're done.
3. You can get a metal door fabricated easily. Sheet metal face and handle (and perhaps a wood cover on the handle). The handle can stand the door up.
4. I have never attached a chimney to that oven. It has a 20cm round opening -- which is slightly thinner than 8". You should try to attach a Duravent chimney system -- double wall UL103 insluated stainless steel. I would try to stick to the 8" pipe for draw. The largest angle that UL allows is 30 degrees, you are limited to two angles (back and up) and a 24" run between the angles (you can download the DuraTech installation guide at
http://fornobravo.com/installation-e...essories.html).
That said, the spec is based on UL certification for wood burning appliances, including fireplaces, which put out a lot more smoke than a pizza oven. I have been pizza oven installations with 90 degree angles that work just fine. Draw typically is not a big issue -- I think it is nature's way of saying that pizza ovens are a good thing.I can't imagine why two 45s would help the oven draw better. Does anybody have a theory on that?
You don't need to go very high to get a good draw, and you want/need a spark arrestor and cap to keep out water.
Let us know how you hook the chimney up.
Have fun!
