Abstract
The invention consists of a colored flame system for illuminating water fountains. A burner assembly, comprising a main burner, a pilot burner, an igniter, a flame sensor and multiple colorant nozzles is located adjacent to one or more water nozzles of the fountain. A control unit oversees operation of the system. Upon commands from an operator, the control unit causes the pilot and main burners to light and injects the desired colorants into the main burner flame. The colorants are concentrated solutions of metallic salts. The flame sensor acts as a safety device insuring that gas and colorants are emitted only when the pilot and main burners are lit. 7
