Hi
ttony604 welcome to Pizza Party family
the gas ovens use LPG and i advice bottle 10kg
LaLabbo heating time 20 minutes, cooking time of neapolitan pizzas 40-70secondi

an expert on gas cylinders, have say me ù, in winter to maintein good working of LPG, change the mix of the gas in the bottle, so that even when it is very cold in winter, the gas burn without problem, try to contact a gas bottle retailer near to you, is this what you wanted to know?
