Used on the Country Flame Crossfire Pellet unit. This board uses the new style wiring harness that eliminates the variable speed control and the on/off switch that was on older models of the Crossfire pellet unit (wire harness is ordered separately, part # PP-1029). This board allows the function of the igniter for lighting the fuel as well as upgraded settings for better fuel burn.  This board would be used if you are upgrading from the NPS-1005-CF control board or have the Post 2008 or newer Pellet fired unit with igniter.
