Abstract
A control mechanism for a gas-fired hot water heater, which operates without a permanent burner pilot, has an electrical circuit for selectively operating an igniter in response to gas pressure in the heating system. The water heater has a main chamber for providing gas to the igniter pilot and the burner element, and a secondary chamber for providing gas to a safety pilot. Circuitry responsive to a high gas pressure in the main chamber activates the igniter and circuitry responsive to a high gas pressure in the secondary chamber interrupts operation of the igniter. Continuous operation of the igniter element is thereby prevented, for example, due to a low gas pressure condition.
