I think you really need to read the whole policy and the context is clear:
Approved Chemical-Fueled Equipment—Commercially manufactured equipment, including stoves, grills, burners, heaters, and lanterns that are designed to be used with chemical fuels.
Prohibited Chemical-Fueled Equipment—Equipment that is handcrafted, homemade, modified, or installed beyond the manufacturer’s stated design limitations or use. Examples include alcohol-burning “can” stoves, smudge pots, improperly installed heaters, and propane burners with their regulators removed.
Recommended Chemical Fuels—White gas (Coleman fuel); kerosene; liquefied petroleum gas fuels, including propane, butane, and isobutane; vegetable oil fuels; biodiesel fuel; and commercially prepared gelled-alcohol fuel in original containers.
Chemical Fuels not Recommended—Unleaded gasoline; liquid alcohol fuels, including isopropyl alcohol, denatured ethyl alcohol, and ethanol; and other flammable chemicals that are not in accordance with the manufacturer’s instructions for chemical-fueled equipment.
Its clear as a bell. Alcohol IS NOT a recommended fuel. Period. They state the recommended fuels for people who do not understand plain english of the "not recommended " ones.
It is not prohibited in a commercially produced stoves, but it is not recommended either.
Most every denatured alcohol has marine stove fuel use on its label. Kleenstrip, slx, Sunnyside, look at them all.
Fuel safety has a lot to do with how its used. A very safe alcohol stove can be made, that wont tip or spill, uses wicks to deliver. Hey , thats how a marine stove works. It will also be heavy enough to negate any potential advantage.
