Because there are so many variables affecting the size of the incoming fuel line, we cannot provide you with a specific answer. We can tell you, however, the fuel consumption rates (as you asked) and fuel pressure that will help your installer determine the correct size gas line. For this unit, the required fuel pressure to the generator fuel inlet at all load ranges is 5 - 7 inches of water column for natural gas and 10 - 12 inches of water column for LP fuel. Regarding fuel consumption, at full load the 14kW Guardian Series uses 220,000 BTU/hr of natural gas or 211,680 BTU/hr of LP fuel. For additional fuel consumption information, please consult the spec sheet for this unit at http://www.generac.com/SpecSheets/0...
