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.
