ABSTRACT:
A direct ignition system for a fuel burner of the type having an igniter, which is mounted proximate to a burner, connected electrically in series with the fuel valve actuator. The system utilizes a voltage sensitive thermal switch which electrically bypasses the fuel valve actuator until a predetermined voltage has been applied to the switch and the igniter for a period of time sufficient to heat the igniter to the ignition temperature of the fuel. When the igniter has reached the required ignition temperature, the thermal switch opens permitting actuation of the fuel valve which allows fuel to flow to the burner.
