Disassemble the Patio Heater

  1. Remove the Emitter Grid: Begin by removing the emitter grid, which is the protective mesh covering the burner. Locate the screws securing the grid and use your Phillips head screwdriver or drill attachment to remove them.

  2. Access the Pilot and Burner Ports: With the emitter grid removed, you’ll have direct access to the pilot and main burner ports, which need to be cleaned.

Clean the Pilot and Burner Ports

  1. Clean the Pilot: Using your air compressor or computer duster, point the nozzle directly into the pilot body and engage the air source to clear out any debris or dust that may have accumulated.

  2. Clean the Main Burner Ports: Similarly, point the air source directly into the main burner ports and engage the air source to dislodge any debris or blockages.

  3. Tip: For stubborn debris, you can use a soft-bristled brush or a toothpick to gently remove any remaining particles.

Reassemble the Patio Heater

  1. Reinstall the Emitter Grid: Once the pilot and burner ports are clean, carefully replace the emitter grid and secure it with the screws you removed earlier.

  2. Reinstall the Reflector: If your patio heater has a separate reflector, make sure to reinstall it properly.

Perform a Leak Test

  1. Check for Leaks: Use the soapy water solution to check for any gas leaks around the connections and fittings. Apply the solution to the connections and look for bubbles, which indicate a leak.

  2. Tighten Connections: If you detect any leaks, turn off the gas supply and tighten the connections using a wrench. Reapply the soapy water solution to ensure the leak has been addressed.

Clean the Exterior

  1. Wipe Down the Housing: Using a soft, damp cloth and mild cleanser, gently wipe down the exterior housing of the patio heater. Avoid using abrasive cleaners, as they can damage the finish.

  2. Polish Stainless Steel: If your patio heater has stainless steel components, use a dedicated stainless steel cleaner/polisher to restore the shine and luster.

Maintain Regularly

To keep your propane patio heater in top condition, it’s recommended to perform this cleaning routine at the beginning of each season or every few months, depending on the frequency of use. Regular maintenance will not only extend the lifespan of your patio heater but also ensure safe and efficient operation.

Remember, always follow the manufacturer’s instructions and safety guidelines when cleaning and maintaining your propane patio heater. If you encounter any issues or have concerns, it’s best to consult a professional for assistance.
