A thermostatic gas heater which permits the user to mechanically select the number of active heating elements, ranging from one to the total number of heating elements. The thermostat mechanically regulates gas flow to all active heating elements. No electricity is necessary for operation because al

대표청구항 ▼

A gas heater comprising: (a) at least four independently operable heating elements with each heating element adjoining at least one other heating element; (b) manually operable control means connected to each of said heating elements for activating a preselected number of said heating elements, said number being selected from any natural number ranging from one through the total number of heating elements in said plurality; (c) thermostatically operable valve means connected to said manually operable control means and serving as the sole means for supplying gas to said preselected number of said heating elements as determined by operation of said manually operable control means, whereby said preselected number of heating elements may be modulated between off and a desired heat setting; and (d) a pilot light system mounted in the vicinity of said heating elements such that the pilot flame is disposed at the juncture of two of said heating elements, whereby gas admitted adjacent each one of said two heating elements will be ignited directly by said pilot light system and gas admitted adjacent the other of said heating elements will be ignited by the gas burning adjacent the surface of an adjoining heating element.
