A nozzle mix, open power burner includes an air housing for receiving pressurized air from a blower. A flame retention plate including a plurality of openings therein is adapted for placement at the outlet of the air housing, so that air supplied to the housing is outletted therefrom through the flame retention plate openings. A gas tube extends through the air housing and includes a gas discharge outlet downstream of the flame retention plate. Gas is discharged from the gas outlet in a direction radially outwardly relative to the longitudinal axis of the gas tube, so that gas is discharged into the flow path of air passing through the flame retention plate. A hot surface igniter is provided downstream of the flame retention plate for igniting the mixed gas and air.
