A method for operating a pulse-fired burner, comprises (a) modulating a fuel supply rate between a pilot and a main level to provide a flame, the level of which flame modulates respectively between a pilot level during a non-firing phase and a main flame level during a firing phase, (b) supplying air at a pilot rate for premix with the fuel before ignition, the pilot air rate being sufficient to support combustion of the fuel at the pilot rate of fuel supply but not at the main rate of fuel supply, (c) and premixing the air with the fuel and terminating the supply of fuel if no flame is sensed.
