I bought a 10k stand by generator, the guardian series by generac...We are having different talks about where it can be installed...We placed it 5ft. on the sides where any windows are,,,18" or alittle more away from the house...now the question is,,.where we placed it 18" from the house to the back of the unit on the house is a outdoor faucet and a 1ft.x3ft. basement window and a oil tank vent...can the generator go there??? 1 person said yes because the window in the basement is stationary and doesn't open and the vent will not bother the generator...what do you think?? I would really like a correct answer
