Because we are asking the Ignis burner to operate throughout the world including places which are either hot or cold and with variable propane quality we have designed the burner to be simple to adjust. The Ignis is fitted with a number of fixed jets and 6 removable jets that stand a little higher than the others. One or more of these jets can be replaced with blanks to change the fuel flow and optimise the burner‘s performance. Your Ignis will be set up for your operating area and it will come with a small bag of blank and regular jets in case you change your flying area.
