The combustion air nozzledirects the combustion airinto the third chamber. A fuel inletcoupled to a burner nozzlesecured to a burner mounting platehas a recycle portfor receiving hot exhaust gas provided to an exhaust gas path. A jet pump located entirely inside the burner housing is configured to receive the hot exhaust gas from the exhaust gas path. The jet pump operates by flowing the combustion air through the combustion air nozzlewhich suctions in the hot exhaust gas through the recycle port into the exhaust gas path then into a gas mixing zonefor mixing the hot exhaust gas and the combustion air.
