KIT-NG FUEL/AIR MIXER, HDF400 | HDXFMXN400

Hayward Natural Gas (NG) Fuel/Air Mixer Kit (HDXFMXN400) is designed for use in the Hayward HDF400 pool heater to properly blend natural gas and air before combustion. This balanced mixture is essential for efficient heating and safe operation.

• Mixes Air with Gas for Combustion:
  The mixer combines a precise amount of natural gas with air to create an optimal fuel-to-air ratio. This mixture is necessary for stable and efficient burning in the combustion chamber.
• Regulates Airflow:
  The mixer controls the amount of air entering the system to ensure it matches the gas supply. Too much or too little air can result in inefficient combustion or safety hazards.
• Supports Complete Combustion:
  By providing the correct balance, the mixer ensures the gas burns completely, minimizing emissions and maximizing heat output.
• Prevents Carbon Build-Up:
  Proper mixing helps prevent the formation of carbon deposits, which can reduce efficiency and require more frequent maintenance.
