I've recently purchased a wood oven seen here - http://aromaticembers.com/Pages/MediumSteel.htm
It's got a number of advantages over the a brick oven I've used before, as its quicker and easier to heat up and use.
However I am having a bit of trouble getting my pizzas anywhere near where I want them. As the title says, they are burnt on the bottom, have some a raw dough middle and there is little rise or bubbles in the dough.
I suspect that it is due to the fire being below the deck, causing it to be too hot on the bottom, hence the burn. So my current technique is to cook the bottom deck for about 1 min, then transfer it to the top rack, to be closer to the roof of the oven to cook the top. This addresses the burnt bottom, but I am still getting raw dough in the middle. The top is throughly cooked though.
Where should I be looking in my process to get a better cooked pizza?
For those interested, here is my process at the moment -
Dough is pretty much the same as Jeff Varsanos recipe (65% hydration, no oil or sugar, sourdough culture, wet kneaded, cold fermented for 1-3 days)
I take the dough out of the fridge approximately 2-3 hours before baking. It's winter here is Australia at the moment, so the house isn't particularly warm (16-20C).
I start the fire in the oven about an hour before baking. During this time, the internal oven temp reaches about 300-350C(570- 660f) and the floor is about 350-400C (650f- 750). By then the coals will have burnt down, and i push them to either side of the oven's fire box.

This is not my photo. Usually my coals are a bit smaller and more burnt down
When the deck is down to 350C (660f) I put my first Pizza in. After about a minute, I transfer it to the top wire rack and finish it off.
I am thinking of replacing the wire rack with another level of fire bricks. This will hopefully lower the deck temperature and increase the heat to the top. However, it will take some time and money to do this, so I want to see if there are other issues with my process that I can address first.
