What kind of gas does a Dometic fridge flame use?
In this case, the gas is a mixture of air & LP gas. For the flame to ignite the ark should pass from the air into the air/fuel mixture. 2) The gas in the space between electrodes becomes ionized (positively charged by removal of one or more electrons). 3) Ionized gas is called plasma.
