ABSTRACT:
A modular ignition assembly for use in a direct fired make-up heater, includes a hot surface igniter disposed adjacent the discharge ports of a pilot tube for providing a pilot flame. The hot surface igniter is surrounded by a tubular shroud for minimizing the effects of cold air and high humidity on the performance of the ignition assembly. A flame sensor is provided for detecting and a sensing the existence of pilot flame and for controlling the gas flow to the burners accordingly.
