Propane fogger operation instructions

Preparation of the fogger

  1. Lock the fogging trigger – Check if your propane mosquito fogger has a trigger lock button. This button locks the fogging trigger so you don’t accidentally press the trigger, while setting up the fogger. This lock button is used for additional safety, because releasing fog unintentionally may be dangerous for the person operating a fogger. Lock the trigger before setting up your mosquito fogger.
  2. Fill container with insecticide – Next step you should do before fogging is to fill the container with an insecticide. To do this, unscrew the plastic or metal vessel that is located under the body of the fogger. The vessel should come off easily. Use only such insecticide or other fogging liquid that is recommended by the manufacturer of the fogger. Insecticides my contain different chemicals and some liquids may be more dense than others which can damage parts of the fogger while fogging. Do not overfill the container, and also make sure that you fill enough liquid for fogger to be able to operate. The pumping tube of some insect foggers may not reach to the bottom of the container, so you need to make sure that the amount of liquid filled in the tank is enough for the fogger to be able to pump it into the coil of the fogger. When you have filled the tank with an insecticide, screw the vessel back to the fogger and hand tighten it firmly so it does not come off in the fogging process. Do not over-tighten the vessel as it may damage thread of the vessel (especially plastic vessels).
  3. Close the fuel valve and insert the propane cylinder – The last thing to do in preparation phase is to insert the propane cylinder. Before this it is important to make sure that the fuel valve is closed. Fuel valve of a propane fogger is usually located on of the sides and closer to the back of the fogger. Turn the valve clockwise (for most propane foggers) to close it and make sure it is properly closed before inserting the propane cylinder. Next thing to do is check for any dust and other debris that is sticking on the cylinder or the back of the fogger where propane cylinder will be inserted. If there are any debris, clean both units before inserting the propane cylinder.

Lighting the fogger

  1. Check if there aren’t flammable materials around – Make sure there aren’t any flammable materials around the fogger before igniting the fogger. Place the fogger on a flat surface.
  2. Check if the fogging trigger is locked – If your fogger is equipped with a trigger lock button make sure that it locks the trigger before lighting the fogger.
  3. Open the fuel valve – Slightly turn the fuel valve counter clockwise to open the gas flow from the propane cylinder to the coil of the fogger. The gas flow should be minimal and you need to hear a gas flow from the cylinder.
  4. Ignite the burner – If your propane fogger has an ignite button, press it. If your fogger does not have an ignite button, light a match or lighter and place under the coil of the fogger. If the igniter does not light the coil of heater after multiple ignition times, close the fuel valve, wait for 2 minutes and than open the fuel valve and try to ignite again. If the burner still does not light, open the fuel valve a bit more, as gas flow might not be large enough. If the burner coil still does not light up check if the gas cylinder is properly attached to the fogger and also check if the cylinder is not empty and replace the cylinder if needed.
  5. Allow fogger to heat for couple of minutes – This step is very important and must be done with all propane foggers. Allow the fogger to heat up for 2 minutes before starting to fog. If you fail to do so the fogger may spit out unwanted fire or the fogger might get damaged.

Operating the fogger

  1. Release the trigger lock – Before starting to fog you need to release the trigger lock by pressing button on your fogger.
  2. Pump the trigger to start fogging – When the burner is heated up for about 2 minutes, you can start fogging. Press the fogging trigger every 4 seconds, this will inject insecticide into the coil, heat it up and turn it into a fog which then sprays out trough the nozzle. You might face some problems in the fogging process:
  • Flame from the nozzle – If unwanted flame appears from the nozzle, stop fogging immediately, place the fogger on a flat surface and turn of the fuel valve. Let the fogger cool down for 10 minutes and repeat the lighting steps.
  • Liquid starts to drip from the nozzle – If you notice that insecticide is dripping from the nozzle this means that your are fogging in too short intervals and need to wait for couple more seconds before next trigger pump or let the burner heat up.
  • Fogger produces a fog in yellow to brown colors – If fog produced by the fogger is in yellow to brown color the fogger is overheated. In this case you need to fog in shorter intervals till the fog reaches white color. But remember no to fog with too short intervals as insecticide could start dripping from the nozzle of the fogger.

Turning the fogger off

  1. Lock the fogging trigger by pushing the trigger lock button
  2. Wait till all insecticide is fogged out – You will have to wait about 2 minutes till all the insecticide will fog out of the coil. In this time you will see fog coming out trough the nozzle of the fogger. After few minutes all the insecticide will be fogged out and you wont see any fog.
  3. Turn off the gas supply – Turn off the gas supply by turning the fuel valve (mostly in clockwise direction). When the fuel valve is closed the fogger burner will burn for few minutes so you will see a little flame around the coil.
  4. Leave the fogger to cool down – Before making further operation with the fogger allow it to completely cool down. This process can take 10 and more minutes and can vary for different products.

Storage of the fogger

  1. Remove the container and propane cylinder – Remove the insecticide container and the propane cylinder from the fogger and store them in a dry, cool and ventilated area.
  2. Empty the container from an insecticide – Do not store the container with an insecticide for longer time and empty the insecticide container after each usage. Clean the container and the fogger from any dust and debris. Storing the container with an insecticide inside may damage the container and the fogger.
