Start by making sure your Thermacell device is on a flat, stable surface. Slide open the battery/mat compartment, and insert an insect repellent mat if it's not already in place. Next, remove the cap from the fuel cartridge, screw it into place, and slide the compartment closed. Move the switch on your Thermacell unit to the “ON” position—this will allow gas to flow. After that, firmly press the “START” button about 2-3 times in rapid succession. Look through the small viewing window to check for a blue glow, which indicates the unit is ignited and working. Wait a few minutes for the repellent mat to heat and begin dispersing protection. If you do not see the blue light, try pressing the START button again or reviewing the fuel connection. Safety tip: Always use your Thermacell outdoors and avoid inhaling the vapor directly.Tips 1:As a designer, I always consider both function and ambiance in outdoor spaces.
