GZ 2 - GZ 4 / 100 - 1450 kW Installation-Operation-Maintenance Rating of the gas ramps Depending on the available gas flow pressure, a correspondingly rated gas compact ramps or gas ramp system will be installed in the factory. If the minimum connection pressure is not achieved under rated heat load, a gas ramp system will have to be used with a larger rated width; the gas pressure must be increased at the utility company's gas transfer point, or the cross section of the supply line between the gas transfer point and the gas ramp system must be enlarged. Before the gas fan burner starts up...
