Abstract
Abstract An electronic spark ignition system for a heating apparatus which does not have a means of attempting repeated ignition attempts if prior attempts at ignition fail is forced into a recycling mode by an independent, self-contained electronic spark ignition recycler. The recycler includes a temperature sensor for detecting output temperature of the heating apparatus, an on/off circuit for activating and deactivating that circuit, a timing determines the length of time allocated for recycling, a triggerable bidirectional switch to force the electronic spark ignition into a repeat mode, and a means for deactivating the recycler after a predetermined condition is met. The temperature sensor activates the timer which periodically triggers the bidirectional switch until ignition occurs or until the recycler is deactivated. Installation of the recycler requires a simple connection of the two terminals of the bidirectional switch to either a wire from the heat demand switch (or thermostat) or a wire from the electronic spark ignition reset switch.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
218 words
In a heating apparatus that relies on an electronic spark ignition system, the system being such that the system's logic will be recycled to its initial state by temporarily lowering the system's temperature activated switch (or thermostat), by temporarily interrupting a power source or control line, or by short circuiting a specific control line, the improvement comprising: an independent, self-contained, easily installed electronic spark ignition recycler means that periodically causes the electronic ignition to attempt a heater apparatus ignition if a previous attempt failed to achieve ignition and proper operation, the recycler means including a power supply means to allow the recycler means to be self contained, a termperature sensor means for allowing the recycler means to be activated or deactivated independently of the logic or electronics contained in the heater apparatus, a timing circuit means for providing periodic positive voltage pulses of predetermined time which determines a time allocated for recycling, an on/off circuit means for activating and deactivating the timing circuit means according to the needs of the temperature sensor means, a bidirectional switch means responsive to said voltage pulse to cause said system's logic to recycle to its initial state, and a means for deactivating the recycler after a predetermined number of ignition attemps have been made or after a predetermined temperature drop has occured.
