I bought the Model M-1 gas appliance from Vamparossa a year ago for my Forno Bravo 39” Artigiano pizza oven. It lets us cook with gas, wood, or both.
The best results come from using gas with a little aged wood, adding just the right amount of heat and smoke for pizza, meats, bread, and veggies.
Unlike a full wood fire, which creates a lot of smoke at startup, the gas option keeps heat steady and avoids smoke issues for neighbors.
I highly recommend the Vamparossa gas burner for a better pizza oven experience.
