Abstract
A method of initiating regeneration of a filter assembly is disclosed. The method includes determining when regeneration of a filter assembly is to be initiated. The method also includes opening a first air valve configured to permit air flow to a regeneration assembly below a predetermined flow rate and at a sufficient flow rate to achieve ignition. The method further includes detecting ignition, and after ignition, opening a second air valve configured to supply air flow to the regeneration assembly above the predetermined flow rate and at a sufficient flow rate for regeneration.
