Locate exhaust outlet far from air inlet to avoid
recirculation. The engine exhaust is tapped for
1-1/2
inch thread. Use flexible tubing to connect theengine
exhaust to rigid pipe or muffler. Shield the line
if
it
passes through a combustible wall (Figure
4).
If turns
are necessary, use sweeping (large radius) elbows. If
pitched upward, install a condensation trap at point of
rise, Figure
