The EU2000i, EU2200i and EU3000is use 4 and 5 inch flexible, aluminum tubes respectively. Because the aluminum tube carries hot exhaust gas as well as emitted, heated cooling air, it can get hot and must be mounted to material that can withstand high temperature. The separate exhaust pipe on the EU6500is and EU7000is must also be routed along material that can withstand high heat to prevent damage or even fire
The cooling air intake for the EU series generators is at the control panel side and emits with exhaust at the opposite side around the muffler (EU2 & 3) and separate upper rear vent on the EU6500is/EU7000is.
Exposed view of generator “enclosure” for depiction only in utilization of directional cooling air flow and exhaust. Use heat resistant material for the construction of your enclosure. An air intake vent must be provided most preferably on the control panel side of the generator.
