This invention provides novel means for supplying pilot and main fuel gas to the fuel gas-combustion air mixing area of a gas-fired space heater employing pressurized combustor means. The pressurized combustor means include an elongate trough having an imperforate base wall and long side walls that are pierced by a plurality of pressurized combustion air inlet apertures, and a fuel gas supply conduit which extends generally longitudinally through the trough. The fuel gas supply conduit has a long surface that is pierced by a plurality of apertures through which fuel gas can enter the trough and be turbulently mixed with pressurized combustion air in a fuel gas-air mixing area, defined by the apertured trough side walls and the apertured fuel gas supply conduit surface, and can be ignited therein to produce an extremely intense heat source flame that is discharged into the space heater heat exchanger means via hollow interconnecting conduit means. The present invention preferably provides its novel pilot and main fuel gas supply means by installing partition means which divide the hollow fuel gas supply conduit into a pilot and a main gas supply potion. And, control and igniter means are also preferably pivoted in accordance with the present invention such that fuel gas will be first supplied to the mixing area via the pilot portion and ignited before any fuel gas is supplied via the main portion.
