Exhaust Hose Connection
1. Connect exhaust system tubes and hoses using at least two hose clamps at each
connection. Tighten hose clamps securely.
NOTICE
Exhaust hoses must be connected to exhaust elbows so that they do not restrict
the flow of discharge water from exhaust elbow. If hoses are connected incorrectly,
discharge water from exhaust elbow will not flow around entire inside diameter of
hose. This will cause a hot spot in the hose which may eventually burn through.
