摘要： An operating and control package for at least one pressurized burner. The operating and control package comprises a controller and a gas control device. The controller is an integrated packaged unit for supplying and controlling a pre-mixed air/gas pressurized burner. A housing is provided for containing the controller. The housing is preferably located at the end of the burner manifold. The gas control device comprises a gas control valve for receiving gas entering the control package and a premix blower located within the housing for receiving gas from the gas control valve and air entering the control package. The gas control device mixes the air and gas to form a pressurized combustible mixture which is fed into the burner.
