Just remove or loosen the drain plug under the vaporizer and wait for the accumulated liquids to finish dripping out of it. Replace the drain plug.

With most installations, the vaporizer would be more accessible. But in my case, it's installed between the engine and firewall, so access is limited. To make my life easier, I just bring it to NAIADSS (the installer for my kit) and have their guys drain it for me.
