ELECTRONIC IGNITION MODULE
The electronic ignition module provides pilot and main gas valve control, pilot burner ignition, and flame monitoring
for the pool heater. The ignition module monitors and controls the function for the pilot gas valve, main gas valve,
and flame status. The ignition module will remain in steady state heating mode until the thermostat opens the water
temperature set point, or the flame being lost. If the call for heat is lost, power is removed from the control,
de-energizing the pilot gas valve and main gas valve.
