<p>In a fryer, a conduit extends through a frypot so as to be immersed in a frying oil. Combustion occurs in an inlet portion of the conduit. Products of combustion are exhausted through an outlet portion of the conduit and through serpentine channels along certain walls of the frypot. Insulative panels form outer walls of the channels, In a burner for the fryer, a vortex of air is provided, and a minor portion of gas is ignited before a valve controlling a major portion of gas is opened. Means provide a minimum delay of one to three seconds, when it has been sensed that combustion has been established, before the valve is opened.</p> |
