A. Exhaust Venturi
B. 1/4" (6.35 mm) minimum clearance all around.
C. 3/4" (19.05 mm) minimum engagement
D. Exhaust Pipe Outlet
NOTE: The outlet pipe must be centered within 1/4" (6.35 mm)
minimum clearance to the exhaust venturi all around the
venturi’s perimeter. If the exhaust pipe touches the venturi,
it will transfer heat and melt the hood. If the exhaust pipe
is not centered, adjust the muffler or outlet as needed to
achieve the necessary clearance.
