Re: Alcohol stove
It's probably an Origo model... Lift up the entire stove unit burners and all (not just the top part that covers the burners). There should be a little button or lever that you pull or slide to release it, then the entire stove unit lifts up on its back hinge.
Once open, you should see a silver canister for each burner. It will have a metal wire mesh over the middle area, covering what looks like wool or cotton.
Take the canister OFF THE BOAT and carefully pour APPROVED STOVE ALCOHOL ONLY thru the mesh, slowly, so it soaks into the cotton. For occasional use, just add about a quarter cup or so because it will evaporate before the next use.
Put it back in the stovetop, close the unit, open the burner cover, move the heat control to full-blast, and stick a fire stick or match into the hold. Woof... You'll see a light blue flame (that can be nearly invisible). Modulate the control to achieve proper desired heat output. Move control to off in order to snuff it out.
At my marina we only have 15a service and our electric stoves continually blow the circuit. Alcohol has been great in my experience -- works very well in all but the windiest conditions (you really shouldn't close all the cabin windows when using the stove).
Hope this helps and good luck.
