IGNITOR, IDL 120VAC | IDXLIGN1931

The Hayward IDXLIGN1931 Ignitor (120V) is a component in Hayward Universal H-Series Low NOx pool heaters, responsible for igniting the fuel-air mixture in the combustion chamber. It ensures reliable and efficient heater operation.

• Power Activation:
• When the heater is turned on, the control board sends 120V power to the ignitor.
• The system runs safety checks to confirm proper airflow, gas pressure, and other conditions.
• Ignitor Heats Up:
• The ignitor, made of durable silicon nitride, quickly heats to around 1,800°F or higher.
• This high temperature is required to ignite the natural gas or propane.
• Gas Valve Opens & Ignition Occurs:
• Once the ignitor reaches the required temperature, the control board signals the gas valve to open.
• The released gas comes into contact with the hot ignitor, creating a flame.
• Flame Sensor Confirms Ignition:
• A flame sensor detects whether ignition was successful.
• If the flame is detected, the heater continues to operate, heating the water.
• If no flame is detected, the system shuts off the gas for safety and attempts re-ignition.
• Heater Runs & Cycles as Needed:
• The burner remains active to heat the water as it flows through the heat exchanger.
• Once the set pool temperature is reached, the heater turns off, and the cycle restarts when needed.
