A gas-heatable appliance for personal use receives an inflammable gas reservoir and comprises a combustion chamber and a valve assembly mounted between the inflammable gas reservoir and the combustion chamber. The valve assembly comprises a valve housing defining a gas passageway, a sealing member mounted in the gas passageway and movable between a first position allowing flow of the inflammable gas and a second position blocking the gas passageway, a movable member mounted in the gas passageway in a position other than the sealing member, and a temperature-responsive member disposed in the valve housing. The movable member is movable by the temperature-responsive member in response to a temperature of the combustion chamber to thereby vary an area of cross section permitting gas flow.
