• providing a hollow housing having a fuel chamber defined by a closed bottom plate, a continuous upright sidewall secured to the bottom plate and extending upwardly therefrom, and a top plate resting on said upright sidewall, said top plate being provided with a generally rectangular opening;
• providing a substantially rectangular baffle cage mounted in the fuel chamber and extending to about one-half depth of the fuel chamber, said baffle cage being provided with a plurality of perforations in a bottom and side walls of the baffle cage and an open top substantially aligned with the rectangular opening of the top plate;
• providing a ceramic fiber filler deposited in the fuel chamber in a surrounding relationship to the baffle cage, said filler being permeated with liquid alcohol;
• allowing alcohol vapor to escape from the fuel chamber into the baffle cage and admix with air;
• providing a protective enclosure configured to receive the housing therein, said enclosure comprising a top peripheral portion, and wherein the flange is configured to rest on the top peripheral portion suspending the housing within the enclosure, wherein the enclosure comprises a closed bottom member, an open top and an upwardly extending sidewall member secured to the bottom member, said bottom member comprising an inner bottom part and an outer bottom part spaced from the inner bottom part, and wherein the sidewall member comprises an inner sidewall part and an outer sidewall part spaced from the inner sidewall part, said inner sidewall part being secured to the inner bottom part, and the outer sidewall part being secured to the outer bottom part.
