Claim 15:
16. The method of claim 15, further comprising the step of:
adjusting at least one of the first fuel injection rate and the first flowrate after the pre-determined start-up period has concluded to produce a second air/fuel ratio within the combustion chamber of the burner assembly that is more lean than the first air-fuel ratio; and
passing the emissions generated by the burner assembly through a filter element located in the connecting tube to trap particulate matter generated by the burner assembly during the pre-determined start-up period and initiate a chemical reaction between the particulate matter trapped in the filter element and nitrogen di-oxide (NO2) in the emissions generated by the burner assembly after the predetermined start-up period.
