A burner assembly including a housing having an air inlet and a burner end, a motor, and an impeller mounted in the housing. The impeller is in fluid communication with the air inlet, in mechanical communication with the motor, and adapted to direct air from the air inlet towards the burner end of the housing. The burner assembly also includes at least one pre-mix gas injection nozzle mounted in the housing. Each of the at least one pre-mix gas injection nozzle has at least one orifice adapted to direct gaseous fuel into the housing. The burner assembly further includes a spin vane comprising at least one spin vane blade. The spin vane is mounted in the burner end of the housing and adapted to direct the flow of air in the burner end. The burner assembly still further includes a flattening screen located in the housing downstream from the impeller and an igniter mounted in the burner end of the housing. The igniter is adapted to ignite the air and fuel mixture in the burner end of the housing to produce a main flame.
