This special main valve action has tremendous feel and gives you the option to independently operate the normal main action part of the burner by engaging the first phase only. However if you then press the valve action an extra step you then engage phase two of the burner giving you the “plus” part of powerplus. The Powerplus Maxi is larger than the Powerplus and has a unique roundbreaking coil design. This is a very powerfull burner designed especially with the commercial balloon pilot in mind.
