    • Ensure the heater is powered off and has completely cooled down before attempting any cleaning.
    • Disconnect the heater from the power source to prevent any accidental starts during the cleaning process.
    • It’s crucial to work with a cold heater to avoid burns and injuries.
  2. Clean the Burn Chamber and Components:
    • Remove the Burn Chamber:
      • Identify and locate the burn chamber within the heater. Refer to the user manual if needed.
      • Carefully detach the burn chamber from the heater. This may involve removing screws or following specific instructions outlined in the manual.
    • Scrape off Loose Carbon and Soot:
      • Use a soft brush or a vacuum cleaner with a nozzle attachment to remove loose carbon and soot from the burn chamber and surrounding components.
      • If the carbon is stubborn, you can use a small, non-metallic scraper to gently scrape away the deposits. Be cautious not to damage any sensitive components.
    • Soak in Cleaning Solution (Optional):
      • Prepare a mild cleaning solution using a mixture of warm water and a gentle cleaning agent. Avoid using harsh chemicals that may damage the heater.
      • Submerge the burn chamber in the cleaning solution for a sufficient amount of time to loosen and dissolve stubborn carbon deposits.
      • Use a soft brush or cloth to gently scrub the chamber and remove any remaining residue.
    • Inspect and Replace Parts:
      • Inspect other components, such as gaskets and seals, for signs of wear or damage. Replace any parts that show significant wear to ensure proper sealing and prevent future issues.
    • Reassemble and Test:
      • Once the cleaning is complete and all components are thoroughly dry, reassemble the burn chamber and any removed parts.
      • Power on the heater and run it briefly to ensure that it ignites properly and there are no unusual smells or issues.
