Gas-fired heater means
Improved gas-fired space heater means, comprising in combination: (a) a first duct-like member being provided within an interior and an exterior, the front end being provided with a combustion supporting gas plenum, and plenum having an inlet and an outlet, the outlet being in flow communication with means for receiving, mixing and igniting a mixture of pressurized fuel gas and a combustion supporting gas; (b) a second duct-like member, surrounding the first duct-like member and the exhaust conduit means and having opposite forward and rearward ends, with the forward and rearward ends of the second duct-like member being respectively located adjacent to the front and rear ends of the first duct-like member; (c) the second duct-like member having a fluid inlet opening located proximate to one of the opposite front and rear ends of the first duct-like member and a pressurized fluid outlet opening located between the opposite front and rear ends of the first duct-like member; (d) means for supplying a stream of the pressurized fluid to the inlet opening of the second duct-like member for discharge through the outlet opening of the second duct-like member; (e) combustion supporting gas intake means are provided with an inlet adjacent to the fluid outlet opening of the second duct-like member and positioned adjacent the second baffle plates and between the first and second duct-like members; and (f) temperature-responsive control for the flow of the combustion supporting gas through the combustion supporting gas intake means in inverse proportion to the temperature of the combustion supporting gas, the temperature-responsive control means including a valve means in the plenum outlet, the vale being operable in response to a temperature sensing means.
