IGNITOR | IDXIGN1930

The Hayward Ignitor (IDXIGN1930) is a hot surface ignitor (HSI) used in Hayward H-Series Ground-Induced Draft Heaters to ignite the gas burner and start heating.

• Heater Call for Heat:
• When the pool thermostat detects the water is below the set temperature, it signals the control board to start the heating process.
• Ignitor Heats Up:
• The control board sends electrical power to the ignitor.
• The ignitor is made of a silicon carbide or silicon nitride material that glows red-hot (around 1200-1800°F) within seconds.
• Gas Valve Opens:
• Once the ignitor reaches the required temperature, the gas valve opens, allowing natural gas or propane to flow into the burner.
• Ignition Occurs:
• The hot ignitor ignites the gas, creating a steady flame in the burner assembly.
• The flame heats the heat exchanger, transferring heat to the pool water.
• Flame Sensor Verification:
• A flame sensor detects the flame to ensure proper ignition.
• If the flame sensor does not detect a flame, the control board shuts off the gas and retries ignition (to prevent gas buildup).
• Heating Continues Until Desired Temperature is Reached:
• The heater continues to run, heating the water, until the pool thermostat reaches the set temperature.
• The ignitor turns off, and the gas valve closes until the next heating cycle.
