• Using a powerful flashlight, examine the circular screen
installed in the end of the exhaust port.There should be
no rips or tears in the screen.There should be little or
no accumulated soot on the screen.
• Replace the screen if torn, perforated or otherwise
damaged. Do Not use a defective screen. Consult
Generac Technical Services for assistance in changing the
screen.
• If screen is not damaged, it may be cleaned in place with
a gentle brushing from a wire brush or bottle brush.
