Abstract

A flame-emitting apparatus is provided, whereby a burner has an inlet connected to a fuel source. Fuel burned by the burner provides a flame extending from an outlet of the burner. A flame ignition system detects the presence of the flame during operation of the apparatus and controls supply of fuel to the burner in response to flame detection.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a Continuation application and claims the benefit of U.S. patent application Ser.
