We recommend that you use a butane torch lighter for optimal results. To ensure even heating, apply the heat to the cap, away from the end, and rotate the device steadily until you hear/feel a click. Directly heating the end of the cap will cause it to click prematurely, causing reduced vaporization.
DO NOT appy heat past the click.
Overheating will premenantley damage the cap.
With a torch lighter and a titanium tip, the typical heat-up phase takes 3-6 seconds and remains at vapor production temperature until the cool-down click about 30 seconds later. After the cool-down click, it is safe to begin another heating cycle. When using a soft flame lighter, the heat-up phase takes about 15 seconds. The stainless steel tip requires a longer heat-up time than the titanium tip.
