Abstract:
1. A system for a gas-fired water heater, the system comprising: a gas valve actuation device configured to actuate a gas valve for establishing operation of a burner of a water heater; an igniter actuation device configured to actuate an igniter for initiating burner operation; and a controller coupled to the gas valve actuation device and igniter actuation device for control thereof based on sensed temperature, the controller being configured to detect the occurrence of an idle time duration in which the burner has been idle for more than a predetermined time, and configured to respond to the occurrence of the idle time duration by actuating the igniter actuation device and the gas valve actuation device for initiating and establishing operation of the burner, to thereby avoid a low temperature condition associated with the water heater as a result of the idle time duration.
