g. A provision of 0-900 mmwc manometer is made after the engine gas manual valve, where the minimum positive pressure should be 50 mmwc at full load (A slightly higher value of 100 mm will give more stable operation). In case, it goes below this limit, then check the pressure drops of the gasifier and filters and if they are within the specified limits then increase the gas by opening the gas control valve at the blower delivery. If the pressure drops of the gasifier increases (refer gasifier troubleshooting section) or if filter drop increases, then action should be taken as per instructions in the gasifier manual.
