The next thing was to actually bake the pizzas. I have set the SmokeFire to 600f / 315c and it reached there quite fast (outside temp was around 0c/32f). I left the SmokeFire around 15minutes and then used an infrared meter to check steel temperature. The temp was around 300c/572f.
I put the pizza in the "oven" and checked it 90 seconds later. The bottom was burnt too much and the top of the pizza was still quite raw. So I put pizza on to the top shelf and tried to rescue what was left. I kept it a few more minutes and cheese started to melt and I removed the pizza from the smoker. Parts were just perfect and parts were burned.
For the next pizza, I put another pizza stone next to steel and started cooking with it. It started good but then I tried to put it on pizza steel which burned the bottom instantly (30seconds). So I went salvage mode again
.
While I was making third pizza I noticed that temps were dropping. The reason was I was out of the pellet. I added more but nothing happened. Pellets kept disappeared inside the smoker but temp did not recover. Then it hit me that the fire has gone out. So I started the shutdown procedure as there is no way currently start the smoker again (or if there is a way please tell me how). Weber should and that function to firmware in case you run out of pellets.
So the third pizza was out of the question. But what happened next was a bit of a surprise. The shutdown mode moved some pellets and the pellets which were piled up inside started to burn. First normally with a little bit a smoke, then a bit more. And around 1 minute later I heard a whooping sound (like a blast) and smoke was everywhere ( I think what happened was that every piece of pellet started to burn same time or something like that). It smokes like hell for 30 seconds or so and then gets back to normal.
Edit: This was due the user error. The I did the shutdown procedure wrong way (thanks goes to Abmet to point me this).
Correct way to shutdown from the manual
1. When your food is cooked to your desired internal temperature, using heat resistant barbecue mitts or gloves, open the grill lid, remove and unplug any food temperature probes from the food and cookbox, and remove all food off of the cooking grates (A).
2. With the grill lid open, push and hold the dial to shutdown your grill (B). Alternatively, you can push the main menu button . Using the dial on the controller, scroll through the main menu and push to select “Shutdown”.
CAUTION: Always engage the shutdown procedure with the grill lid open to properly shutdown your grill when finished cooking. Frequently interrupted cook cycles could cause component failure.
3. Your SMOKEFIRE grill will run through a series of steps in order to properly and safely shutdown your grill. Once the shutdown procedure is complete and the grill has cooled, power off your grill (C) and unplug from the power source.
4. Close the grill lid (D).
